Fitzpatrick: A Parasitic Species of Claudopus 37 
Peck.* The spores of the two species are approximately the 
same size, and are both typically uniguttulate. The fungus on 
Polyportis perennis is evidently closely related to C. depluens. 
It cannot, however, if the differences enumerated are taken into 
consideration, be regarded as identical with it, and the following 
name is proposed : 
Claudopus subdepluens sp. nov. 
Pileo e convexo expanso, minuto, 1-4 mm. maximam diam., 
albo, minute tomentoso, margine sulcato; lamellis ex primo sal- 
nioniis, distantibus, adnatis, acie integerrima ; stipite albo, lateral!, 
flexuoso, adusque 2 mm. longitudinem, crassitudine minore quam 
0.5 mm. ; basidiis 4 sterigmatibus praeditis, clavatis ; sporis an- 
gulosis, i-guttulatis (raro 2-plus-guttulatis), parum atqui definite 
roseis, 7-12 X 6-8 /j..
