7M THE AGARICACEAE OF MICHIGAN 



attachment of the gills shade into the genus Trichololna. C. multi- 

 ceps appears after prolonged rainy weather, and when developed 

 rapidly it is quite tender and sweet. The clusters are often densely 

 crowded and may usually be recognized by their firmness and dull 

 white color. 



775. Clitocybe cartilaginea Bres. 



Fungi Tridentini, 1892. 

 Illustration: Ibid, PL 111. 



PILEUS 4-8 cm. broad,, convex, obtuse, dry, provided with a 

 cartilaginous cuticle, smoky-tan or whitish-tan, tinged with gray 

 or brown, glabrous, even, margin splitting. FLESH white, thick. 

 GILLS crowded, attenuate subdecurrent, sometimes adnate and 

 becoming sinuate or almost free when old, narrow, tough, sub- 

 cartilaginons, attenuate at both ends, sordid white to pale straw 

 color. STEM 5-7 cm. long, tapering upwards or subequal, 1-2 cm. 

 thick at apex, stout, paler than pileus, somewhat spongy-clavate 

 at base, cuticle toughish, solid, pruinose above, subfibrillose, bases 

 somewhat connate. SPORES globose, 5-7 inicr., nucleate, smooth, 

 white. CYSTIDIA none; basidia 30-32x0-7 inicr. ODOR and 

 taste mild. 



Caespitose. In woods. June, etc. 



Sent in from outside the southern boundary of the State, and 

 apt to occur within the State. The darker colors of the' cap, and the 

 straw-colored, truly crowded gills seem to be the only characters 

 besides the cartilaginous cuticle of the pileus, by which to separate 

 pale forms of C. cartilaginea from C. multiceps. Superficially, the 

 habit, etc., of the two species are much the same. It was placed 

 among the Tricholomas by Fries as T. loricatum. When quite young 

 the color of the pileus is smoky-black.
