406 THE AGARICACEAE OF MICHIGAN 



pallid or dingy. CORTINA whitish, thin. UNIVERSAL VEIL 

 white at first, leaving thin subannular shreds or a slight annulus 

 on the lower part of stem, soon sordid brownish. SPORES ellipt- 

 ical, slightly rough, 8-10 x 5-G micr., pale ochraceons under micro- 

 scope. ODOR and TASTE slight. 



Gregarious. Bulb imbedded in wet moss and soil under spruce 

 and balsam trees. North Elba, Adirondack Mountains, New 

 York. August-September, 1914. Collection Kauffman. Frequent 

 locally. 



Well marked by the dense tomentosity of the cap when young 

 and by the pallid gills. Even under the most favorable conditions 

 the violet-bluish tint of other parts than the stem was scarcely no- 

 ticeable. It agrees well with the Friesian description, but is not the 

 plant of Quelet (Grevillea, Vol. 7, PL 112, Fig. 1), nor that of 

 Ricken. At times the hygrophanous character is deceptive as the 

 cap becomes darker with age. The universal veil is thin in small 

 plants and the species could be looked for under Inoloma. It differs 

 from C. cahesceus by its spores and by the violaceous stem when 

 young. It is possible that G. catskillensis is a dry weather form of 

 this species.

PILETJS 3-10 cm. broad, fragile, conico-campanulate, prominently 

 umbonate when expanded, hygrophanous, sometimes irregular or gib- 

 bous, purple-fuscous to brownish-vinaceous (Ridg.), faded and silky 

 in dry weather, margin soon wavy, at first incurved and silky from 

 the veil, glabrescent. FLESH thin, concolor or violaceous when 

 moist. GILLS emarginate, adnate, thickish, broad, rather distant, 

 ventricose, at first violaceous-purple then cinnamon-brown, edge 

 whitish. STEM 10-15 cm. long (rarely 15-20 cm.), 8-20 mm. thick, 

 cylindrical or a II en noted toward base, sometimes flexuous, pale 

 lavender to deep violet, more deeply colored at the base, marked by 

 annular shreds of the violaceous then whitish universal veil over 

 most of the surface, spongy and solid, concolor within. SPORES 

 elliptical, slightly rough, 8-9.5 (rarely 10) x 5-6 micr. ODOR slight- 

 ly of radish. CORTINA fibrillose. whitish, evanescent. 



Gregarious or subcaespitose. On moss, decayed debris and humus
