ENDOTHIA PARASITICA AND RELATED SPECIES. 21 
the septum, hyaline with a gelatinous envelope, 7.5 to 10.5 by 3.5 to 5 wu, mostly 
8 to 10 by 4 to 4.5 uw. 
CULTURAL CHARACTERS.—Cultures one month old on white corn meal show 
small numerous, thickly scattered pycnidia and ‘spore masses very similar to H. 
parasitica. The mycelium is orange buff to apricot orange. This species differs 
from #. parasitica in culture, chiefly in the brighter color, of its mycelium. 
Host.—Rotten logs and stumps of Hlaeocarpus glandulifer. 
TYPE LocaLity.—Hakgala, Ceylon. 
GEOGRAPHICAL DISTRIBUTION.—Only known from Ceylon at present. One 
other collection of this species, No. 290 G. H. K. T. [Thwaite], N. Eliya, 
Ceylon, 6,000 feet, has been examined in the Kew Herbarium. 
Through the kindness of Mr. T. Petch, of Peredeniya, the writers 
have received two large collections of this fungus. Some of the 
material was in a living condition and enabled the writers to obtain 
pure cultures for comparison with the other species of Endothia. 
This species is closely related to £. parasitica, but is readily sepa- 
rated by its larger ascospores and larger and more variable pycno- 
spores and its nonparasitic habit.

TYPE SPECIMEN.—Herbarium N. Y. Bot. Garden, on Castanea dentata, Bronx 
Park, New York City, Nov. 26, 1905, Coll. W. A. Murrill. 
- Pycnip1a.—Stromata corticular, slightly erumpent to truncate conical, usually 
separate and gregarious, frequently confluent in more or less linear series 
especially in old rimose bark, 0.75 to 3 mm. in diameter by 0.5 to 2.5 mm. 
high, varying from capucine yellow when young to auburn when old and 
weathered ; pycnidia consisting of irregular cavities in the stroma, 100 to 300 
# in diameter ; sporophores mostly simple, subclavate, acute at the apex, usually 
12 to 20 by 1.5 wu, more elongated filaments sometimes reaching 50 « or more 
being frequently found among the normal sporophores; pycnospores, oblong to 
sylindric, rounded at the ends, 3 to 5 by 1.5 to 2, mostly 3.5 to 4.5 by 1.5 to 
2 w, pale yellowish in mass under the microscope; old spore tendrils coral red. 
PERITHECIA.—Stromata the same or similar to the pycnidial stromata; peri- 
thecia dark, membranous, globose to flask shaped, collapsing when dry, 5 to 50 
or sometimes more in a stroma, 300 to 400 uw in diameter, irregularly arranged 
in one to three layers and bearing slender necks projecting above the stroma, 
300 to 600 », colored like the stroma on the outside and terminating in acute 
ostioles ; asci oblong elliptical to subclavate, nearly sessile, 30 to 60 by 7 to 9 By 
mostly 40 to 50 by 8 »; ascospores irregularly biseriate, ellipsoid, obtuse, some- 
times constricted at the septum, hyaline, with a gelatinous envelope, 7 to 11 
by 3.5 to 5», mostly 8 to 9 by 4 to 4.5 wu. 
CULTURAL CHARACTERS.—Cultures one month old on white corn meal have a 
white to pale orange yellow surface mycelium and produce numerous minute
