subiculum spreads widely, producing only here and there a few 
scattered perithecia. Some of Greville’s specimens of Crypto - 
sphceria aurantia (t. 78) are undoubtedly this species.

7. Hypomyces ochxaceus, Tub Conidia: Tufts effused, wooly, 
white ; flocci erect, septate, pellucid ; branches and branchlets 
subulate, verticil late, patent ; conidia diaphanous, ovate, obovate, 
or oblong, straight, usually simple, sometimes uniseptate ; *05-*06 
mm. long by *004-*006 mm. wide. 
Chlamydospores produced by the deeper and larger flocci in linear 
series of 2-4 ; each chlamydospore is globose, *02-*03 mm. wide, 
slightly rough, at first white, becoming dirty or vinous-red. 
Perithecia crowded, roundish, yellowish, universal, with a short, 
thick, obtuse exserted mouth, seated upon a subiculum, which is at 
first white, then straw-coloured, ochraceous, and yellow. 
Asci linear, cylindrical ; *025-*03 mm. long by *0065 mm. wide. 
Sporidia eight ; oblong-lanceolate, uniseptate, constricted, 
mucronate at each end ; *035 mm. long by *0065 mm. wide.

I have never met with this species, which seems more inclined 
to affect the fleshy Agaricini. Tulasne records it upon Russula 
emetica , and advsta. Ditmar’s figure of the conidia is upon a 
Russula as well as Greville’s figure of the conidia (t. 126) and of 
the perithecia (t. 78.) It is only right, however, to state that 
some of Greville’s specimens now extant in the Kew Herbarium
