cell cavity, the other remaining in the beak and disintegrating. 

 One of the pair of parent cells then enlarges, a pore opens into 

 the adjoining smaller one, the protoplast from the smaller flows 

 over into the cavity of the larger, and the t^vo nuclei finally fuse. 

 Soon a thick \\'all is formed around the zygote. 



Fig. 43. Massospora cicadina. A. Conidial formation from conidiophores 



that extend to the exterior of the body of the parasitized cicada. B. 



Conidium. C. Early stage in formation of resting spore within the 



cicada's body. D. Mature resting spore. (Adapted from Speare.) 



Comdiobohis iitriciilosiis also forms zygotes, but neither their 

 germination nor that of any other of this assemblage of fungi has 

 with certainty been observed. 



Kevorkian (1937) regards Comdiobohis inllostis, commonly 

 held to be saprophytic, as a parasite on termites in Cuba. He 

 also concluded that its minute conidia, borne at the appendage 

 tips of the resting conidia, are like those which characterize 

 Delacroixia coronata and therefore placed the latter name in 

 synonymy w'lxh C. viUosiis,
