Mycologia 
margins with neighboring fruit bodies is more or less characteristic 
of the species. It was evident in many of the plants collected, 
has been described before, and is not to be regarded as due to the 
presence of the parasite. Nearly one hundred fruit bodies of the 
Claudopiis^ the majority of them in the “ button ” stage, may be 
counted on the single sporophore pictured. They are shown en- 
larged to approximately two diameters. The lower figure in the 
plate illustrates the parasite in somewhat more detail, the en- 
largement here being nearly four diameters. 
The fungus must be regarded as a member of the genus Claud- 
opus. The stipe is definitely lateral. The spores, salmon-colored 
in mass, when viewed under the microscope exhibit a distinct pink 
tint. However, no previously described species of the genus 
posesses the characters of the fungus on Polyponis perennis. 
No described species of Pleurotns or Crepidotus resembles it even 
remotely. The pileus is white, the lamellae are salmon-colored 
in even the young fruit bodies, and the spores are definitely angu- 
lar (see text figure i). Few species of the genus have been 
described as having angular spores. Only one of these, Claudopus 
dephiens Batsch, has a white pileus, and it is described as being 
sometimes tinged with pink or gray. The minimum measur- 
ment (one-half inch) given as the diameter of the pileus of C. 
depluens is three times greater than the maximum of the species 
under consideration, while average pilei of C. depluens are much 
larger. The fruit bodies of C. dephiens occur on the ground or 
on decaying wood, and arise from saprophytic mycelium. The 
lamellae are at first white, later becoming salmon-colored. The 
species has been collected in New York and was described by 
Fig. I. Spores of Claudopus subdepluens Fitzpatrick.
