PREFACE.
The term mycology is here used in the broad sense including
not alone the study of fungi, but also the slime-moulds and bacteria.
During Spanish occupation of Porto Rico, little attention was
given to mycology, the earliest recorded collection being that of
Carl Schwanecke made during his residence in Porto Rico, 1847-
1850. The fungi of this collection, consisting of seventeen species,
were determined and published by J. F. Klotzsch. A second and
larger collection was made by P. Sintenis, 1884-1887, the determina-
tions being made by J. Bresadola, P. Hennings and P. Magnus.
Since annexation by the United States the work has been
greatly extended through the operations of the Insular Depart-
ment of Agriculture and by a number of botanists who have
visited the island for longer or shorter periods. Among these are
A. A. Heller and Mrs. Heller, during the early part of 1900; G.
P. Clinton in 1904; and E. W. D. Ilolway in 1910. Numerous
collections of fungi have also been made by Dr. and Mrs. N. L.
Britton and other collectors from the staff of The New York Botani-
cal Garden at intervals from 1906 until the present time.
Bruce Fink of Miami University, Ohio, visited the island in
1915 primarily for the collection and study of lichens but brought
back a goodly number of fungi. The same year H. II. Whetzel
and E. W. Olive spent several weeks in Porto Rico devoting most
of their time to researches on the rusts. Their collections have
been studied and reported on by J. C. Arthur.
Probably the largest single collection of fungi was that obtained
by F. L. Stevens during the years of his residence as Dean of the
College of Agriculture at Mayaguez. His collection of rusts was
also studied by J. C. Arthur and reported by him. Other groups
of fungi have been studied by Professor F. L. Stevens and his
collaborators at the University of Illinois and reported on at various
times.
In 1923, Dr. Seaver, at the request of the Porto Rican govern-
ment, spent several weeks in company with Dr. and Mrs. N. L.
Britton, exploring Porto Rico and the Virgin Islands. Mr. Chardon,

then connected with the Insular Experiment Station at Rio Piedras,
collaborated with us during our stay in Porto Rico. More than a
thousand collections of fungi were made including many additional
species for the region.
In 1924 H. H. Whetzel of Cornell University made a second
trip to Porto Rico, this time accompanied by F. D. Kern of The
Pennsylvania State College to continue work on plant rusts. On
most of their excursions they were accompanied by Rafael A.
Toro of the Experiment Station at Rio Piedras. This expedition
again resulted in adding much new material to the store already
accumulated. Part of the results of this work has been reported
in preliminary papers and the remainder is incorporated in the
present work.
Local students, especially those connected with the Depart-
ment of Agriculture, have added their contributions, so that the
fungi of Porto Rico are now probably better known than those of
any equal area in the American tropics. Our knowledge of the
plant rusts is particularly complete. But notwithstanding this,
some groups of the fungi have scarcely been investigated and are
still in need of intensive study.
While the fungi of Porto Rico have been rather carefully
studied, the Virgin Islands were, so far as we are aware, unexplored
by American mycologists until our visit in 1924, although a few
species had been reported by European students. For this reason
the two weeks spent on the larger islands, St. Thomas and St.
Croix were full of interest. About fifty per cent of the fungi col-
lected were new to the islands and a fair number new to science.
The results of this work have been reported in preliminary papers
and incorporated in the present work with detailed citations.
In 1918, J. A. Stevenson, at that time Pathologist at the Insular
Experiment Station, published "A check list of Porto Rican fungi
and a host index." This was a very complete summary of our
knowledge of the fungi of Porto Rico up to that time, and has
been invaluable to us in the preparation of the present catalogue.
For the determination of hosts we are indebted to Dr. N. L.
Britton and Mr. Percy Wilson and for bibliographical aid to Dr.
J. H. Barnhart.
DESCRIPTIVE FLORA.
Phylum 4. THALLOPHYTA.
Plants not differentiated into leaf and stem, one to many-celled, with or
without chlorophyl, reproducing by direct cell-division (fission) or by means of
special reproductive bodies known as spores which may be formed either sexually
or asexually.
Plant tissues partially or entirely chlorophylless.
Thallus entirely chlorophylless.
Vegetative stage devoid of cell-wall.
Vegetative stage possessing cell-wall.
Reproducing by fission, without mycelia
structure.
Reproducing by means of spores, usually
possessing mycelium.
Thallus consisting of chlorophylless fungouss)
tissue and chlorophyl-bearing (algal) tissue.
Plant tissues chlorophyl-bearing.

Class 2. SCHIZOMYCETES.
Class 3. FUNGo.
Class 4. LICHENS.
Class 5. ALGAE.
Class 1. MYXOMYCETES.*
The Myxomycetes, commonly known as slime-moulds, comprise a large
group of living organisms of doubtful affinity. Some include them with the
animal kingdom, others with the vegetable. While the vegetative stage is
animal-like, consisting of living, moving protoplasm, the fruiting stage is fungus-
like so that the group is often treated with the fungi. The most of the forms are
saprophytic and of no known economic importance while a few are known to be
the cause of serious diseases of the higher plants.

The Chytridiales are parasitic fungi of simple structure often consisting of a
single cell. They live on other plants and animals such as protozoans, desmids,
algae and other fungi. Some also occur as parasites on the stems and leaves of
the higher plants.

species of Dolicholus.
Order 2. PERONOSPORALES.
The Peronosporales represent an order of parasitic fungi including the
"white rusts" and "downy mildews." This group includes two of the most
destructive parasites known, the "grape mildew" and the "potato blight," the
latter often being responsible for the destruction of a large per cent of the potato
crop wherever this plant is grown. Both of these species have been reported
from Porto Rico.

This sub-class comprises one of the two great groups of the fungi and the
many species are characterized by having their spores produced in closed sacs or
asci from which they are forcibly ejected at maturity. The group includes a
large number of parasitic species although many are saprophytes of no known
economic importance.

Order 1. SACCHAROMYCETALES.
Family 1. SACCHAROMYCETACEAE.
This order of plants includes the yeast plants and other low fungi. The
yeasts are concerned in alcoholic fermentation and in the manufacture of bread.
They are unicellular plants which reproduce by budding. Under rare conditions,
however, they reproduce by the formation of spores endogenously. On account
of the resemblance of these spores to those of the ascomycetes the order is usually
included with the latter.

16 ASPERGILLACEAE
Dr. Bailey K. Ashford, of the Institute of Tropical Medicine of Porto Rico,
has kindly supplied the writers with the following information regarding this
interesting human pathogen: "I consider this organism to be the definite factor in
producing the sympton-complex known as "sprue." It colonizes in the human
intestine, however, apparently only when a certain degree of acidity and an
abundance of starch and sugar is furnished. It seems generally to require func-
tional derangement of digestion, with a peculiar variety of food unbalance to
provide an ideal intestinal enriching medium."

Order 3. ASPERGILLALES.
This order includes plants of very diverse habits, such as the underground
fungi, none of which have been reported from Porto Rico, also such forms as the
green moulds belonging to the genus Penicillium and the similar genus Asper-
gillus. Both of these genera have been placed here because some of the species
have ascigerous stages. Whether all of them produce the perfect stage is a
question which cannot be answered.

Order 5. PERISPORIALES.
The order includes the powdery mildews, few of which occur in the tropics,
and the sooty molds which are very abundant in tropical lands, occurring mostly
as epiphytes following insects and often destroying them.
Vegetative mycelium white. Fam. 1. ERYSIPHACEAE.
Vegetative mycelium dark or occasionally
wanting.
Mlycelial hyphae not slimy, septate, branch-
ed net-like; peridium parenchymatous,

4. Erysiphe Malachrae Seaver, sp. nov.
1Mycelium scant but covering the greater part of the upper side of the leaf,
giving it a whitish appearance, the tissue of the leaf being slightly discolored;
perithecia numerous. at first white, becoming pale brown, subglobose, reaching a
diameter of 60-75 p, almost devoid of appendages, usually containing three
asci; asci ellipsoid, about 30 X 40 p., apparently 5-spored; spores ellipsoid, about
14 X 20 I, hyaline.
On living leaves of Mealachra capitata L., Porto Rico: -endemic.
This species is unique in many ways so that its position in the genus is open
to question although it is undoubtedly one of the Erysiphaceae. The perithecia
are unusually small, almost devoid of appendages and at most only pale brown
instead of black. So far as we are aware this is the only member of the family
reported from Porto Rico with the ascigerous stage developed at all. Later col-
lections may give us more detailed information on the species and its relationship.

Order 6. CORYNELIALES.
The plants comprising this order are typically parasitic although one or two
species usually placed here are saprophytes. The family Coryneliaceae is usually
included with the Perisporiales or the Sphaeriales but according to Fitzpatrick
(Mycologia 12: 206-237) does not fit either order well and is here treated as a
separate order.

Order 7. PSEUDOPERISPORIALES.
RAFAEL A. TORO.
Family 1. PSEUDOPERISPORIACEAE.
Aerial mycelium, colored, septate; perithecia superficial on the mycelium, os-
tiolate, parenchymatous, with or without appendages; asci globose or elongate,
spores various; paraphyses present or absent.
The order differs from the Perisporiales in having perithecia with definite
ostiolum.

On Meliola Panici Earle, on Panicum glutinosum Sw. Herbarium University
of Illinois, Porto Rico Fungi (Stevens) 6796, (Type) Arecibo, Jan. 17, 1914.
This fungus has been referred to Dimcrium piceum (Berk. & Curt.) Theiss. by
Stevens (Bot. Gaz. 65: 229). It is not a Dimerium, because the perithecia are
ostiolate. It further differs from D. piceum in the absence of paraphyses and
much smaller spores.
PSEUDOPERISPORIUM gen. nov.
Mycelium superficial, brownish, non-hyphopodiate; perithecia globose,
membranous, leathey, parenchymatous, setose; asci 8-spored; spores 4-celled,
hyaline; paraphyses wanting.
The genus is related to Dimeriella Speg. from which it differs in the presence
of ostiolum.

collapsed at the top and slightly pezizoid, smooth, with an ostiolum present; asci
clavate to subelavate, 8-spored, 40-60 X 12-15 p; spores inordinate in the ascus,
fusiform to subeylindric, 7-9-septate, with greenish contents, 22-26 X 4-6 p.
42 NECTRIACEAE
This species was determined in the herbarium as Nectria episphaeria, but a
microscopical examination of it showed that the determination is incorrect. It
possesses multiseptate spores, a character which makes it fall under Calonectria.
In the treatment of the Hypocreales by Scaver (N. Am. Fl. 3: 12-13. 1910),
only three species of Calonectria are reported from North America. Our species
differs from all three of them in the size and septation of the spores and also in
the complete absence of a mycelium at the base of the perithecia.

material is scant and its identity, rather doubtful.
6. Creonectria rubrosulphurea Seaver, sp. nov.
Perithecia thickly congested, forming clusters about 4 mm. in diameter,
each cluster containing few to many perithecia, the individual perithecia red,
but covered with a beautiful coat of sulphur-yellow hairs; perithecial hairs,
short, about 6-10 p in diameter, several septate, blunt and often curved or
hooked at the ends, minutely rough; asci clavate, 25-30 X 6-8 g; spores partially
2-seriate, narrow ellipsoid, 4-6 X 8-12 p, at maturity distinctly striate.
Type collected on dead cane, Rio Piedras, Feb. 3, 1914, J. R. Johnston 1346;
also on dead stick, 5696, Porto Rico:-endemic.
In external appearance the species very closely resembles Nectria flavociliata
to which name it was first referred. The plants, however, on closer examination
are found to differ in the stromate character of the perithecia and the spores which
are broader and distinctly striate. In this latter character it resembles Nectria
rhytidospora. -,-:
NECTRIACEAE 43
7. Creonectria macrospora Chardon, sp. nov.
Perithecia in cespitose clusters, 2-3 mm. in diameter, densely crowded,
surrounding a yellowish to orange colored stroma, the clusters containing 20-30
or more perithecia, individual perithecia large, 400-500 M in diameter, dark
red and possessing a brownish disk around the region of the ostiolum; asci clavate,
8-spored, 90-120 X 15-24 p; spores biseriate, seldom uniseriate above or below,
oblique elliptical to subfuscoid, 1-septate, large, 21-29 X 9-11.5 p, hyaline, densely
granular.
This interesting fungus has been referred to Nectria Balansae Speg. and pub-
lished as a new combination under the genus Creonectria. Dr. Spegazzini has
kindly supplied the author with a portion of the type of his species, from which
the Porto Rican species seems to differ widely. The spores are much larger and
the perithecia are provided with a conspicuous brown disk on which the ostiolum
is centrally located. Furthermore, the perithecia never become pezizoid, while
in N. Balansae, they are characteristically so. This last character, however,
might be due to the old age of Spegazzini's material.
The species being essentially different from Spegazzini's and also from all
the species of Creonectria given by Seaver from North America is given here as
new. Prof. F. L. Stevens' No. 2965, collected in Caracas, Venezuela, is also to
be referred to this new form. The perithecia and spores are somewhat larger,
but otherwise, the fungus agrees with the above description. The species pos-
sesses larger spores than any other Creonectria known from North America.

2. Sphaerostilbe mammiformis Chardon, sp. nov.
Stromata consisting of several slender stalks, 1-2 mm. high, of a pale orange
color, with several globose heads (Stilbum); conidia ellipsoid, 1-septate, with
hyaline, granular contents, 23-26 X 8-10 j; perithecia in dense, cespitose clusters,
following the crevices of the bark, 15-30 in each cluster, pale yellow, provided with
a distinct red, mammiform ostiolum, the individual perithecia 500 A in diameter,
subglobose and not collapsing; asci cylindrical clavate, S-spored, 90-100 X 12-
15 y; spores mostly biscriate, subfusoid, 1-septate, not constricted, 22-23 X 5-6 /A;
provided with several greenish oil drops.
This species is characterized by the possession of a very conspicuous, mam-
miform ostiolum of a different color than the perithecia.

During a recent collecting trip in Porto Rico this species was found to be very
abundant on the above plant host. No attempt was made to identify the insect
host. It is possible that this fungus might be successfully used in checking the
insect parasite.

110-112 X 10-12 p, with a pedicel 10 p long; spores obliquely uniseriate, fusi-
form or subfusiform, 16-20 X 6-8 p, continuous, hyaline; paraphyses filiform.
On Cyperus ligularis L. Cornell University Explorations of Porto Rico
(Whetzel, Kern & Toro, 264S type). Vieques, July 17, 1925.
This fungus is unique for several reasons. The stromata are formed in the
upper portions of the big air cavities of the host leaves. From the base of each
stroma a compact weft of brown mycelial hyphae arise and penetrate the host
PHYLLACHORACEAE 55
cells below the cavities. In this respect it resembles Phyllachora Thwaitesii
(Berk.) Sace. The generic position of the fungus is also questionable. Possessing
mostly uniloculate stromata it is difficult to decide whether we are dealing with a
Dothideaceous or a Sphaeriaccous fungus. However, since most of the Phyl-
lachoras on grasses are of this type the fungus is placed in this genus for the
present. It also suggests Puiggarina Speg. a genus which has been established
for uniloculate species of Phyllachora devoid of paraphyses. Our species, how-
ever, has paraphyses and it will necessitate the establishment of a new genus.

This species is characterized by the possession of a very irregular, confluent,
black stroma on the upper surface of the leaves. It is a true Trabutia since its
stroma is located between the cuticle and the epidermis.

The genus Trabutia Sacc. & Roum. has been transferred to the Dothideales by
Theissen.and Sydow because its type species T. quercina has a distinctly dothide-
aceous stroma, no cell wall being present. So far as the writers are aware all
the known species of the genus belong in the Dothideales. The new genus
Clypeotrabutia is proposed here to take care of the 1-celled, hyaline-spored forms
of the Clypeosphaeriaceae. A cross section of the type species of this genus,
Trabutia portoricensis shows the presence of a true perithecial wall bordering the
perithecia and shows also a distinct clypeus bordering the region of the ostiolum.

Spots numerous, subcircular in outline, light colored in the center with a dark
brown border, reaching a diameter of 1 mm.; perithecia few to each spot and
usually located near the center of the infected area; asci clavate 40-45 X 8 p,
4-spored (so far as observed); spores fusoid, 1-septate, hyaline 12-14 X 3-4 s.
On living leaves of Commelina elegans 11. B. K.
Type collected at Mayaguez, February, 1923. No. 418. All spots do not
show perithecia and it is not easy to get asci and spores. After some persistence,
however, several mounts were made. Only four spores could be detected in the
asci examined. Some ascomycetes which normally produce eight will sometimes
show only four mature ones. So some allowance should be made in case the
number should be found to vary.

2. Hypoxylon citrinum Shear, sp. nov.
Stromata subpulvinate, very irregular in shape, erumpent, gregarious or
scattered, occasionally confluent, with somewhat irregular surface but thin and
fragile, gray at first on the outside becoming dark chestnut to black with age and
bright lemon yellow to golden within; 1-3 mm. across, frequently only 2 or 3
perithecia in a stroma and occasionally with separate perithecia; perithecia de-
pressed-globose, mostly embedded in the scanty stroma, about /2 mm. in di-
ameter, with a thin, fragile wall; ostioles papillate, small, black; asci cylindrical,
stipitate, 75-85 p long; paraphyses not seen; ascospores overlapping-uniseriate,
short elliptic to subglobose, continuous, smooth, dark brown, 10.5-12 X 7-8 p.
Type, No. 378 Seaver & Chardon on dead corticate branches, Porto Rico,
1923, in Pathological Collections, U. S. Department of Agriculture and New York
Botanical Garden.
The most striking character of this species is the bright light golden color of
the inside of the stroma, which is usually noticeable in the specimens on account
of their fragile character. The plant might have been referred to Rosellinia on
account of the perithecia being occasionally separate, gregarious or only slightly
united in stromata, but no description of it could be found under that genus.

4. Hypoxylon leucodermium Shear, sp. nov.
Stromata subpulvinate, discoid or irregular in outline, superficial, appressed
to the surface of the bark and attached at the center by a narrow base, gregarious
or somewhat scattered, occasionally confluent, surface smooth or slightly rough-
ened by the ostioles, carbonous without but soft within when fresh, whitened
without when young with a thin, compact conidial layer which gradually disap-
pears with age, apparently finally becoming black, white within, Y4-1 cm. in
diameter, 2-3 mm. thick; perithecia black, globose to subglobose, entirely em-
bedded in the stroma, %4-1 mm. diameter; ostioles black, very slightly elevated,
small; asci cylindrical, stipitate, p. sp. 180-200 X 13-15 ; paraphyses doubtful.
The asci appear to be embedded in a hyaline gelatinous layer lining the inner
surface of the perithecia. Spores uniseriate or slightly overlapping, elliptical,
inequilateral, smooth, continuous, dark brown, 23-30 X 10-11.5 p.
Type, No. 632 Seaver & Chardon on decaying corticate branches, Porto
Rico, 1923. In Pathological Collections, U. S. Department of Agriculture, and
New York Botanical Garden.
The nearest relative of this species with which we are acquainted is Hypoxylon
Berterii MIont., which we also have from Porto Rico and which is readily distin-
guished by the size of its ascospores, which are only 10-12 X 5-7.5 ;, according
to the type specimen which we have examined. Both species are somewhat
intermediate in character between Hypoxylon and Xylaria in having the substance
of the stroma of the structure and color of Xylaria and being attached at the
center of the base.
