198 THE AGARICACEAE OF MICHIGAN 



Gregarious or solitary. On the ground, in moist places, bare 

 ground, woods, thickets, etc. August-October. Ann Arbor, Detroit. 

 Infrequent. 



This species is similar to the preceding in general appearance. It 

 is separable from it by its large spores, the slightly adnexed gills 

 and the white base of the stem ; it has also a more viscid cap and a 

 somewhat fibrillose stem. It also differs from H. chlorapanous in 

 its red colors and dry stem. 



Var. flavescens Kauff. (8th Eep. Mich. Acad, of Sci., 190G.) 



PILEUS smaller, 2-6 cm. broad, "luteus" yellow, varying to 

 orange tints in places, then citron yellow, fragile, convex-campanu- 

 late, expanded, glabrous, even, viscid, sometimes wavy. GILLS 

 adnexed, rather broad, close to sub-distant, pale yellow or white, 

 subveiny. STEM 4-7 cm. long, 3-G mm. thick, hollow, compressed, 

 sulphur or citron-yellow, base white, moist, pellucid-shining, gla- 

 brous, sometimes pellucid-striate. SPOKES smaller, -i-T.") x 4-5, 

 elliptical. 



Gregarious, in wet places, moss, etc., in cedar swamps or low 

 woods, in northern Michigan. Rather frequent. 



The viscidity of the pileus is not very marked. It has much the 

 habit and coloring of H. chlorophaiwus, but the stem is never viscid 

 and varies in color to a distinct citron-yellow with white base, and 

 is usually compressed. It is a distinct species as shown by its 

 spores.

PILEUS 2-5 em. broad, convex or campanulate, then nearly 

 plane, obtuse, viscid, citron, sulphur or golden yellow, glabrous, 

 sometimes pellucid-striate on margin. FLESH fragile, not becom- 

 ing black when bruised. GILLS adnexed, rentrieose, becoming 

 emarginate, thin, subdistant, rather broad, pale citron-yellow, trama 

 of parallel hyphae. STEM 3-7 cm. long, 4-8 mm. or less in thickness, 

 equal or nearly so, sulphur or pale citron-yellow, unieolorous, hoi-
