540 THE AGARICACEAE OF MICHIGAN 



remote, not broad, pruinose, white then bright piuk from spores, 

 edge concolor. STEM about 2 cm. long, equal, curved, silky, white 

 or tinged fuscous, striate. SPORES oblong, G-G.5x3 micr., smooth, 

 pink. CYSTIDIA about 50 micr. long, slender, sometimes curved 

 and rounded al the apex, abundant on sides and edge of gills. 



Solitary. On rotten logs, in woods. New Richmond. Rare. 



The fibrillose pileus allies this form with this section. The oblong 

 spores, characteristic of the species according to Massee, induced 

 me to place it here although the absence of "bluish down" which 

 Pries italicises may indicate that it is a different or undescribed 

 species. It seems to be close to var. drepanophyllus Schultz, the 

 status of which is uncertain. 



578. Pluteus tomentosulus Pk. 



X. V. State Mus. Rep. 32, 1879. 



Illustration: Atkinson, Mushrooms, Fig. 133, p. 139, 1900. 



PILEUS 3-7 cm. broad, thin, soon expanded, obtuse, umbonate, 

 ■floccose-tomentose, more densely so on disk, white or tinged with 

 pink, especially on the margin, margin even. FLESH thin, white. 

 GILLS free, rather remote, crowded, broad, white then rose-colored 

 from the spores, edge fimbriate. STEM 5-10 cm. long, 4-8 mm. 

 thick, equal, solid, GbriHose-striate, subbulbous at base, slightly 

 tomentulose, bulb tomentose, white. SPORES subglobose, or 

 broadly short elliptical, 5-7x4.5-5.5 micr., smooth, rose-flesh color 

 in mass. CYSTIDIA stout, 85-95x22-25 micr., not horned, bottle- 

 shaped on a rather slender stalk, scattered, more numerous on edge 

 of gills. 



Solitary or scattered. On rotten logs or prostrate trunks, es- 

 pecially in hemlock, tamarack or cedar swamps. Throughout the 

 State: Marquette, Houghton, Sault Ste. Marie, New Richmond, 

 A.nn Ailx.r. July, August, September. Frequent in the northern 

 pari of State. 



This is a beautiful species but prefers deep swamps. In Europe 

 P. pellitus !•>.. a more glabrous species, takes its place. Accord- 

 ing to Peck, the pileus often has a pink tinge.
