348 THE AGARICACEAE OF MICHIGAN 



maple, etc. August-September. Ann Arbor, Detroit. Rather 



rare. 



This magnificent species lias only been seen thrice. It was at 

 liist passed by as G. purpurascens but a careful examination re- 

 pealed important differences. It may be considered as a segregate 

 of thai species, although very likely it is a native of this country. 

 \u European author seems to have referred spherical spores to 

 G. purpurascens or G. subpurpurascens, and in the European plants, 

 both of these species entirely or partly lack the purple color of the 

 cap. No very young specimens were found, and it needs further 

 study. Both this species and the preceding approach the next sub- 

 genus in i lie scarcely marginate bulb. 



331. Cortinarius purpureophyllus sp. nov. 



PILEUS 5-8 cm. broad, convex-expanded, dull tawny-red, fading 

 to ochraceous-fulvous, glabrous, even, with a viscid, separable pelli- 

 cle, margin incurved. FLESH whitish, thick, compact. GILLS 

 rounded behind and adnexed, deep lilac-purple, color persistent, 

 narrow, crowded, thin, edge entire or suberoded. STEM 4-6 cm. 

 hnig, L2-18 mm. thick, equal or slightly narrower upwards, pallid 

 or slightly tinged lilac-violaceous at first, spongy-stuffed or solid, 

 fibrillose from cortina, apex violaceous within, with a marginate-de- 

 prcssed, flattislt bulb, which is white throughout, attached to a 

 white mycelium. CORTINA copious, whitish (?). SPORES al- 

 mond-shaped, elliptical, tuberculate, 10-12x6-7 micr., rusty-cinna- 

 mon in mass. BASIDIA 3642x8-9 micr., t-spored. ODOR slight 

 or none. TASTE slowly disagreeable, somewhat bitter. 



Gregarious. Among fallen leaves in frondose woods of maple, 

 oak, etc Ann Arbor. October-November. Infrequent. 



Known by the contrasting colors of pileus, gills and stem, and 

 the size of the spores. The flesh is scarcely tinged with violaceous 

 excepl ;it the npex of the stem. The young gills have a deep color 

 as in G. purpurascens, but the flesh has none of the characteristics 

 Of that species.
