THE AGARICACEAE OF MICHIGAN 



debris. Ann Arbor, New Richmond, etc. Probably throughout the 

 state. June- September. Frequent. 



Known by the reddish covering of the stem. Hard says the plants 

 are very small, which is scarcely correct. The name is deceptive, 

 since the tomentose covering of the stem more often extends 

 nearly or quite the whole length of the stem and the species could 

 with equal propriety be referred to the next division.

Epicrisis, 1836-38.

PILEUS 2-2.5 cm. broad, convex then expanded or depressed, ob- 

 tuse, pale brown with tinge of flesh color, to pale isabelline, rugose- 

 sulcate, glabrous. FLESH submembranaceus, tonghish. GILLS 

 adnate, seceding, sometimes with tooth, rather narrow, close to 

 subdistant, concolor or paler than pileus, thick somewhat 

 crisped. STEM 5-7 cm. long, 2-3 mm. thick, equal, hollow, horny- 

 tough, dilated at apex, dark rufous-brown downwards, white and 

 glabrous above, clothed- by a whitish or pallid villosity which is 

 denser below, attached by incurved or straight base to veins of oak 

 leaves. SPORES narrowly lanceolate, curved, accuminate at one 

 end, 12-15 x 3-4 inicr., smooth, white. ODOR strong, of garlic. 



On midribs of fallen oak leaves, in rich woods. Ann Arbor. 

 September. Infreqttent. 



This differs from M. scorodonius in the villose coating of the 

 stem, and from M. alUaceus by its habitat on leaves and by the 

 spores; both of those have a garlic odor. Cooke (111.) gives the 

 width of spores as 8 niicr., and this appears to have been copied by 

 most authors who give the spore size. Ricken departs from this in 

 assigning to it minute spores, 7x1 inicr. This last discrepancy 

 points to a different species, and may represent M. polyphyllus Pk. 

 in Europe.
