(310), 
where Pseudomeliola has been placed. On the other hand, the 
perithecium is evidently complete, the upper and lower walls 
being both fully developed, in which it agrees with the Peri- 
sporiaceae. The spores are shorter than in the type of Pseudo- 
meliola and it is possible that they ultimately become 2- 
septate. 
MICROTHYRIACEAE. 
Asterina Sidae sp. nov. 
Mostly epiphyllous, forming poorly defined, thin, blackish 
patches 2-4 mm. in diameter; mycelium scanty, of zigzag 
radiating threads about 4 4 thick; hyphopodia sessile, irreg- 
ular and conspicuously three- or four-lobed, 7-8 3 perithecia 
aaa scatiered, 80-100 #, convex-applanate, of dar 
e, Closely agglutinated, radiating hyphae, subostiolate, 
eanae stellately ; asci subglobose, 8-spored, 20-25 #4; asc 
spores inordinate, ovate, somewhat unequally one 
strongly constricted, fuliginous, 14 x 
On living leaves of Svda carpinifolia, pauses: Earle, no. 
366 (type); Porto Rico, Heller, no. 6333. 
Parasitized by Dzmerosporium Se ee sp. nov.* 
The parasite is much more abundant on the Porto Rican 
specimens. 
Asterina triloba sp. nov. 
Epiphyllous, forming black patches 2-4 mm. in diameter or 
often confluent; mycelium rather scanty, of dark fuscous 
threads, about 4 # in diameter, hyphopodia scattered, sessile, 
irregular, but usually three-lobed, about 7-8 4; perithecia 
abundant, shield-shape, consisting of radiating threads, some 
of which exceed the margin, forming an irregular Lemdbosza- 
like subiculum, 30-50 # wide, rupturing stellately, 90-120 
in diameter; asci broadly ovate to suborbicular, about 25— 
30 yt, ascospores hyaline to full maturity, then dark brown, 
about equally uniseptate, constricted, elliptical, ends obtuse, 
about 20-25 x 8-9 p. 
On living leaves of Croton discolor. Limestone hills, 
along the coast west of Ponce, Porto Rico, Heller, no. 6216. 
This differs from Asterzna crotonicola Pat. in the three- 
lobed hyphopodia and smaller spores. The specimens also 
show abundant dark brown, opaque, obovate conidia, about
