rounded by sharply defined concentric lines." The figure represents a spore of the 

 Grijlli type which bears little resemblance to that of TS. Muscae, so that any determina- 

 tion based upon the figui'c and description is not possible. 



TaricMa tivella, Krassilstchik I. c, p. 95. 



Under this name Krassilstchik has described a fungus, growing in coleopterous lar- 

 vae, which is characterized by the production of a mass of brick-red " Taricliiuni''' spores 

 produced by a process not observed, and cohering in small, grape-like clusters as indi- 

 cated by the specific name. The spores are described as round, papillate, 8-10/^ in di- 

 ameter, surrounded by a wall of no great thickness. In a nutritive fluid they germinated 

 in four days, producing septate hyphae which after a week grew out of the culture fluid 

 and produced single, terminal, cylindrical, colorless spores, 9 X 3//. 



This does not appear to be an Empusa from the course of development described, al- 

 though it might possibly be related to 31assospora. Concerning this, it is, however, im- 

 possible to judge without figures or more detailed information concerning the species.-'

Comdia{?) produced from short hyphae or hyphal bodies, tvithm the host; nearly spher- 

 ical to ovoid, tapering towards a small basal papilla of attachment; smooth or papillate- 

 verrucose, 10 X 18,a-18 X 25,^, forming a yellowish mass in the abdominal cavity ex- 

 posed as a coherent mass by the falling away of the abdominal rings. Resting spores (?) 

 spherical, roughly i-eticulated, slightly colored, 38-50/^ in diameter (Peck). Host not 

 attached to substratum.

This singular form should, I think, imdoiibtedly be placed among the EntomopMhoreae, 

 although it is decidedly anomalous in some respects. Professor Peck is inclined to place 

 it near Protomyces among the Coniomycetes ; owing perhaps to the fact that the origin 

 of the spore mass from the characteristic entomophthoroid bodies (figs. 415-419) was 

 not apparent in the types. Whether these spores which fill the whole abdominal cavity 

 are morphologically similar to the conidia of Empusae, or are a kind of azygospore or 

 chlamydospore I am unable to say, having examined only dried material in which it 

 was, of course, impossible to discover the exact process of formation and separation. 

 Their general appeai'ance is certainly that of conidia; yet, unless a columella can be 

 demonstrated in connection with their formation they must be regarded as of a difierent
