NEW NORTH AMERICAN FUNGI. 



101 



Spores oblong-elliptical or obovate, 4-septate with a short, narrower, 

 subcorneal, hyaline cell at each end, intermediate cells brown. Crest of 

 3 hyaline, spreading bristles about 7—10 long. Basidia about as long 

 as the spore, slender. Colored part of the spore 12—16 x 6—7 p-. Differs 

 from P.funera, Desm, in its constantly smaller spores. 



AsTERiNA DiscoTDEA, E. & M.., in Am. ivTat. This occurs also on 

 leaves of Olea Americana, not differing specially from the form described 

 on leaves of Quercus laurifoUa. It may be that this is the A. oleina, Cke.. 

 Grev. XI, p, 38. The description there given is not inconsistent with this 

 supposition. In that case, A. discoidea, E. & M., is a synonym of A 

 oleina, Cke. Unfortunately, the specimen of this latter species in Rav. 

 F. Am., no. 757, in our copy, does not show even a perithecium. 



MiCKOSPH^RA DENSISSI3IA, Schw.— What appears to be this species 

 was found on leaves of Quercus laurifoUa, at Green Cove Springs, in 

 January and February, 1885. Mycelium thick, gray, persistent, confined 

 to definite spots on the lower surface of the leaf, 8—10 mm. in diameter. 

 Perithecia black, globose, then depressed, 120 /^-. Appendages stout, con- 

 tinuous and subhyaline, twice dichotomous, ultimate divisions curved. 

 96 — 120 X 7 Asci 6. Sporidia 6—8, oval, granular and nucleate, 21 — 

 25 X 12 P: The branched tips of the appendages are often of a pyramidal 

 shape, the main axis running through and bearing a second set of 

 branches shorter than the first.

 and sporidia.
