-1 



On leaves of box (Buxus). Not uncommon. 



Forming an exceedingly tliin white film on the under 

 surface of tlie leaves. Cooke first detected the 

 present species mixed with Pemcillium roseum, which 

 he considers to be the gonidial form of the Mucor, but 

 there is no evidence of such connection, unless the

 substratum is considered as such, which cannot 

 possibly be accepted. 



Phycomyces, Kunze. 



Sporangiferous hyphas at first erect, simple, 

 aseptate, shining, often very long; sporangia 

 spherical or piriform, very delicate, brown, ruptured

Mucor, Berk. OutL p. 307 ; Cke. Hdbk. p. 630. 



Remarkable for the dry glistening nature of the 

 hypha3. Distinguished ivomMucor by the base of the 

 sporangium remaining as an irregular ring or frill 

 round the columella, and by the arcuate, or arched^ 

 spiny branches of the zygospore. 



Phycomyces nitenSj Kunze. 



Hyphasma dense, effused, dry, olive-brown, shining ; 

 sporangiferous hyph^e often springing in clusters of 

 3- — 4 from a mycelial hypha, when 1 — 2 are usually 

 sterile, brown, shining, decumbent, aseptate ; spor-
