CLASSIFICATION OF AGARICS 



at margin. iilLLS adnate becoming emarginate with decurrent 



tooth, niirrmr, crowded, yellow then ferruginous, edge iiiiinilil;, 



floccose-fimbriate. STEM stout, I LO cm. long, 7-15 mm. thick, 

 compact, often hard, solid, subventricose, peronate-scaly, fibril]* 

 in age, concolor to fuscous below the ring, pruinose and paler above. 

 ANN! l.i s near apex of stem, membranaceous, persistent, thin, 

 mostly entire, yellowish. SPORES broadly-elliptical, 7-9x5-G 

 micr., ferruginous, tuberculate-rough. CYSTIDLA cone, I >u t <■ 

 of gills are tufted with sterile cells. TASTE markedly bitter. 



Growing 1'nmi the base of yellow birch trunks. Marquette, V 

 bish Island. August-September. Infrequent. 



A very imposing and elegant plant. Its colors, narrow gills, 

 apical ;iuiiiiliis. bitter taste and rough spores separate this from 

 all others. P. adiposa has similar colors l>ut differs widely in ;ill 

 other respects. The figures of European authors Bhow the plant 

 with a peronate stem in ils best condition and they are excellent, 

 but somewhat misleading after the annulus has become pendant. 

 The spores are similar to those of many Oortinarii.
