784 THE AGARICACEAE OF MICHIGAN 



late, obtuse, at first purplish-maroon then livid-reddish or paler, 

 glabrous, striate, stained darker in age; the sterile margin extends 

 beyond the gills and is crenate. FLESH thin, bleeding when cut. 

 GILLS narrowly adnate, ascending, narrow, subdistant, whitish 

 soon reddish-stained, edge flocculose. STEM 4-8 cm. long, 1.5-3 mm. 

 thick, rigid, fragile, hollow, white-pruinate when young, at length 

 glabrous except the hairy base, even, rufous-tinged, exuding reddish 

 juice when broken. SPOKES elliptical. 8-10 x 5-6 micr. (few larger) r 

 smooth, white. CYSTIDTA none. Sterile cells on edge of gills 

 numerous, with swollen-ventrieose base and tapering to a narrow 

 acuminate point, about 50 micr. long. ODOR and TASTE mild. 



Caespitose or subcaespitose, sometimes confluent, on decaying 

 wood. In frondose and coniferous woods throughout the State. 

 June to September. Lather frequent. 



Known by the reddish juice of the flesh, the crenate flaps on the 

 margin of the cap and the caespitose habit. The juice is not always 

 equally abundant depending on weather and vigor of plant. All 

 the parts of the plant become stained darker reddish in age. Fries 

 does not mention the striations on the cap, which are sometimes 

 quite marked. 



A variety occurs on hemlock logs whose pileus is often markedly 

 umbonate, at first striate, very rugose striate in age, its margin 

 scarcely crenate. The gills at length secede ami remain attached 

 to each other behind by a false collar, often very veiny ami staining 

 reddish after being bruised. The stem and cap also become reddish- 

 stained from the watery juice contained in the liesh. The juice 

 itself seems uncolored but causes the bruised parts to assume the 

 reddish stains. The base of the very caespitose stems is imbedded 

 in cracks in the logs and is strigose with white hairs. It was col- 

 lected during several seasons at New Richmond. It occurs in dense 

 clusters. The spores are like those of M. haematopa.

PILEFS small. 4-0 mm. broad, soft, campanulate, obtuse or sub-
