POLYSTICTUS (OR TRAMETES) CUNEATUS, FROM 

 J. M. GRANT, WASHINGTON (Fig. 848). I took the types at 

 New York, as Mr. Grant suggests, to be 

 same as Polystictus Sequoiae, but these 

 are better specimens and show them to be 

 quite different. This species has same 

 surface, texture and similar pores to Tra- 

 metes hispida, and should be classed to- 

 gether, though Trametes hispida is a bet- 

 ter Polystictus than Trametes. The con- 

 text is pure white, and at first I considered 

 the probability of it being a white form of 

 Trametes hispida. But I found the spores 

 globose, 5-6 mic. transparent with a large, 

 opaque gutta, with no suggestion of the 

 cylindrical spores of Trametes hispida. I 

 therefore consider (now) Polystictus cun- 

 eatus to be a good species, though the 

 name has no application whatever to these 

 specimens. 



GUEPINIA OCCIDENTALIS, FROM 

 J. M. GRANT, WASHINGTON (Fig. 

 849). Color light yellow, pale lemon yel- 

 low when soaked. Obconic with a short 



stipe. Disc flat, 3 mm. Stipe short, merging into the cup. Exter- 

 nally glabrous, but under the glass surface of hyaline, palisade, inflated 

 cells. Basidia forked, with yellow, guttulate contents. Spores sub- 

 cylindrical, arctuate, 5-6 x 20 

 mic., septate when old, with 

 granular, pale yellow con- 

 tents. 



The genus Guepinia con- 

 sists of stipitate, tremellaceous 

 plants with forked basidia, 

 and subcylindrical spores 

 which are septate when old. 

 It has the hymenium on one 

 face only. We have in the 

 eastern United States one 

 common species, G. spathu- 

 lata, one fairly common, G. 

 elegans, one very rare, G.
