Classification. 1 03 



* 

 On dung. Rare. 



Mixed with 3Iucor muceclo. Closely resembling* 



Chwtocladium Jonesii in general appearance, but 



distinguished by the smaller sporangia and spores. 



SUBFAM. 4. MORTIERELLE^. 



Vegetative hyphse slender, anastomosing ; sporangia 

 globose, polysporous ; columella absent. 

 Mortierella. The only British genus. 



Mortierella, Coemans. 



Mycelium slender, dichotomously branched and 

 anastomosing; sporangiferous hyphje erect, often 

 originating in small clusters, thick at the base and 

 tapering upwards, simple or branched, branches 

 terminated in a single spherical sporangium without a 

 columella. Zygospores and chlamydogonidia present 

 in some species. 



Mortierella, Coemans, Bull. Ac. Belg. ser. ii. part 

 i. p. 536, t. 15.; Sacc. Syll. vii. p. 220. 



The leading features of the present genus are the 

 anastomosing mycelium, and the absence of the colu- 

 mella in the many-spored sporangium. The branches 

 are frequently arranged in a verticillate or corymbose 

 manner, and taper upwards. 



Mortierella poly cephala, Coemans (figs. 29, 30). 



Mycelium aseptate, dichotomously branched, 

 branches elongated, very slender ; sporangiferous 

 hyphge erect, fasciculate, fusiform, 260 /jl high, 

 branched in a racemose manner ; sporang'ia globose, 

 hyaline, wall difiluent, containing 4- — 20 ovate or 

 globose hyaline gonidia, 9-14 /n diameter. Chlamy-
