There are two varieties of this species, one with larger, pointed perithecia, 

 as figured by Greville and by Albertini and Schweinitz ; the other with smaller 

 and more obtuse perithecia. The sporidia vary a good deal in size, as does the 

 colour of the subiculum, which is sometimes nearly absent. Sometimes it is al- 

 most white, but mostly rose-coloured, with a whitish circumference. Fuckel's H. 

 roseus does not seem to differ from the typie species except in the size of the 

 sporidia. This species is totally distinct from the species pointed out by Messrs. 

 Berkeley and Broome in the Annals of Natural History, No. 971, and described in 

 this monograph as Hypomyccs Berkleyanus.

6. Hypomyces aurantius, Tul. Conidia: Mycelium creeping, 

 branched, septate, white (becoming orange), sending up erect branched, verti- 

 cOlate, conidiiferous threads, which bear upon their apeces ovate or obovate, 

 hyaline, unequally uniseptate, slightly constricted conidia "016 to '018 mm. long 

 by -008 --01 mm. wide. 



Perithecia springing from a more or less abundant effused, floccose, 

 ochraceous subiculum, which is often white circumferentially, crowded, subcon- 

 fluent, sphaerical, with a conoid-attenuate apex, golden yellow or orange, '3 mm. 

 in diameter. 



Asci cylindrical ; '11 to '14 mm. long by "006 mm. wide. 



Sporidia eight ; uniseriate, linear lanceolate, acute, often apiculate at either 

 end ; uniseptate or bipartite ; hyaline, curved ; '015 to '024 mm. long by '004 to 

 •006 mm. wide.
