6. Hypomyces aurantius, Tul. Conidia : Mycelium creeping, 
branched, septate, white (becoming orange), sending up erect 
branched, verticillate, conidiiferous threads, which bear upon their 
apices 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 circumferen- 
tially, crowded, subcontluent, spherical, 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 apicu- 
late at either end; uniseptate or bipartite ; hyaline, curved ; *015 
to '024 mm. long by *004 to *006 mm. wide.

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 perithecia are then often crowded together in 
clusters, as Greville’s figure (t. 47) represents. At other times the
