172 THE AGARICACEAE OF MICHIGAN 



154. Gomphidius flavipes Pk. 



N. Y. State Mus. Rep. 54, 1901. 

 Illustration: Ibid, PL I, Fig. 1-4. 



PILEUS 1-2.5 cm. broad, convex or plane and sometimes uin- 

 bonate, viscid, dingy pink or yellowish, tinged reddish, minutely 

 tomentose on center, slightly fibrillose on the margin. GILLS 

 decurrent, arcuate, subdistant to distant, scarcely forked, whitish 

 then pale smoky-brownish. STEM 3-5 cm. long, 3-7 mm. thick, 

 equal or tapering down, solid, slightly fibrillose, whitish at apex, 

 elsewhere yellow within and without. SPORES elongated-fusi- 

 form, 20-30x6-7.5 micr., smooth, smoky-brown to brownish black. 

 CYSTIDIA present. 



Solitary or gregarious. On the ground in mixed woods. Harbor 

 Springs. September. Rare. 



Only one collection has been made of what seems to be this plant. 

 The spores were clearly immature and had not yet attained the 

 size given by Peck. 



Hygrophorus Fr. 

 (From the Greek hugros, moist; and phero, to bear.) 



White-spored. Consistency of the gills waxy; of pileus and stem 

 waxy-fleshy or fleshy. Hymen ophore continuous with the trama of 

 pileus and stem. Stem central. Gills variously attached, soft, not 

 membranous, edge acute. Hymenium loosely adherent to the trama 

 of the gills. Trama of gills various: parallel, divergent or inter- 

 woven. 



Putrescent, soft, terrestrial mushrooms, growing in woods, 

 meadows, etc., and uniformly harmless. They are medium or small 

 in size and often brightly colored. The gills are usually distant or 

 subdistant, characters which ordinarily distinguish them from the 

 species of Clitocybe for which those with decurrent gills might be 

 mistaken. The genus corresponds to Gomphidius and Paxillus of 

 the ochre-spored group, but is distinguished from them by the gills 

 not easily separating from the trama of the pileus. 



The PILEUS varies from conical to convex at first, in most cases 

 becoming plane at maturity, with or without an umbo and some- 

 times umbilicate. In a great many species the expanded pileus is 

 obversely subcorneal, pulling the gills into an ascending position,
