Based on a half specimen (270) from A. Yasuda, Mikawa, Japan. The habitat not stated. 

 It appears to have had a short stem which was enlarged above, the cup-shape pileus adnate 

 and prolonged above the stem. There is no analogous species in Europe or America, in fact 

 it could be made a new genus based on the white context of the hymenophore, different from 

 the hymenium and the distinct, well formed papillae, and it might be classed in the Hydna- 

 ceae. However, the spore character is typically that of Thelephora, and one European species 

 (T. terrestris) has a blunt, granular hymenium. I think it better to stretch the limits of the 

 genus to include it than to multiply the genera. 



NOTE 223. Isaria (unnamed), received from A. Yasuda, Japan. This is what passes 

 in Japanese literature as "Isaria arachnophila Ditm." and a bad misdetermination, for Isaria 

 arachnophiia is a little species not 2 millimeters long, and this is a large club-shape specimen 

 6 centimeters or more. It is an example of what errors can be made in naming fungi from 

 descriptions. The species should be renamed, for it is something unique. It grows on a large 

 spider, or the specimen looks to me more like a cocoon. It is compact and has a general 

 resemblance of being a Cordyceps, but the spores are conidial. I do not know of any other 

 Isaria that has any resemblance to it. It was sent as a "conidial form of a Cordyceps," but 

 no Cordyceps corresponding to it has been named from Japanese material and I doubt if the 

 connection can be traced. It is assumed generally that conidial bodies en insects are conidial 

 forms of Cordyceps, but in most cases it is principally a deduction. Tulasne was quite posi- 

 tive that Isaria farinosa is a conidial form of Cordyceps militaris, which De Bary at first dis- 

 puted and then virtually admitted. I am under the impression it has been demonstrated re- 

 cently in the laboratory. They are different phases of the same fungus, but the Isaria form 

 does not change into the Cordyceps form. They are developed under different conditions 

 from the host.
