 Nov., 1879. 



This species varies very much in the amount and colour of the subiculum. 

 Sometimes this is nearly absent, it being invisible to the naked eye. The peri- 

 thecia are then often crowded together in clusters, as Greville's figure (t. 47) 

 represents. At other times the 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 ochraceus, Tul. Conidia : Tufts effused, woolly, 

 white ; flocci, erect, septate, pellucid ; branches and branchlets subulate, verti- 

 cUlate, patent ; conidia diaphanous, ovate, obovate, or oblong, straight, usually 

 simple, sometimes uniseptate ; "05- "06 mm. long by '004- 'OOG mm. wide. 



Chlamydospores produced by the deeper and larger flocci in linear series of 

 2-4 ; each chlamydospore is globose, "02- '03 nun. 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, ochraceus, and yellow. 



Aid 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.
