ROLAND THAXTER ON THE 



This species which is said to occur on grasshoppers seems to be peculiar from its col- 

 ored conidial spores which, according to Sorokin, are reddish brown, round and resemble 

 those of E. Muscae except in color. The protoplasm from the basidium is discharged 

 with the spore. Sorokin states that it closely resembles E. Grylli, differing, however, 

 by its round and colored conidia. It is in this species that Sorokin has observed peculiar 

 amoeboid bodies within the host which produce resting spores laterally or terminally. 

 For some further account of this species a review of Sorokin 1 may be found in J ust's 

 Bot. Jahresbericht (1881), p. 292, by Batalin. 



Entomopldlwra Tipulae, Fresenius I. c, B p. 206, figs. 46-50. Sorokin I. c. C, p. 211, 

 fig. 651. 



I find no mention of the occurrence of this species since it was described and figured 

 by Fresenius. The conidia are described as ovoid, with a short, broad, rounded, pro- 

 jecting base ; measuring 33-40/7. in length. The figures represent a broad almost truncate 

 base and ovoid body which gives the spore a characteristic outline. The species was 

 found on a large Tipula which was wingless and adhering to a rush. The mass of spores 

 and hyphae had a greenish brown color. The form should be readily recognized by the 

 large size and peculiar shape of its spores, yet I have seen nothing like it on similar hosts 

 in this country. 



Entomoplithora Callip7iorae, Giard I. c. 



Entomophtliora muscivora (E. Calliplwrae Giard?), Schroeter I. c, p. 223. 



The species described by Giard on large flies ( Calliplwra) can, I think, hardly be dis- 

 tinct from the E. muscivora of Schroeter since the rare peculiarity of a deep chestnut- 

 brown (pnarron fonce) resting spore, the measurements of which are the same (30// in 

 Calliplwrae and 24-28// in muscivora) is common to both. The hosts and habit corre- 

 spond in the two forms, E. muscivora differing only in the fact that its conidia are also 

 described, while in E. Calliplwrae they were not observed. Schroeter describes the co- 

 nidia of his species as ovoid, with a blunt papilla; 20-24// long by 11-13,* broad. On large 

 flies which are attached by numerous rhizoids. The conidia are slightly smaller than in 

 the form that I have described as E. Americana from which it is separated by the pecu- 

 liarity of the resting spores.

 C, p. 235. 



The conidia of this species almost exactly resemble those of E. echinospora and E. Amer- 

 icana, being somewhat long-ovoid with papillate base and rounded apex. Like E. Amer- 

 icana they contain numerous small oil globules of very regular size ; but the species is 

 at once separated from either of the forms just mentioned by its peculiar cystidia which 

 are very large, resembling those of E. sepulchralis (fig. 306). The conidia measure from 

 22,u to 28// in length by 14// in breadth. The resting spores are zygospores produced by 

 a Spirogyra-like conjugation and are of the usual type, 31// in diameter. The species 

 occurs on flies: Lonchaea vaginalis, Syrphidae, Sapromyza, etc., and is found in wet 

 situations on damp ground, planks, etc.
