6 4 THE AGARICACEAE OF MICHIGAN 



This species is considered identical with the preceding by Ricken r 

 Massee and Romell. Even Fries was loath to separate it, and con- 

 sidered it a var. of M. peronatus. (See note under M. urens. Epi- 

 crisis, p. 373.) According to Mcllvaine, M. peronatus is edible, 

 while M. urens is marked poisonous. If the two are identical this 

 can hardly be true. There is a remote possibility that Collybia 

 hariolorum has been confused with M. peronatus while testing its 

 edibility. In any case one needs to be careful. M. urens if distinct, 

 seems more abundant locally than M. peronatus. The latter alone 

 seems to have been differentiated by Peck, who does not report the 

 first. Moffatt (Nat. Hist. Surv. Chicago) reports only M. urens and 

 says it is frequent. Morgan (Myc. Flora. Miani.) reports both. 



29. Marasmius subnudus (Ellis) Pk. 

 N .Y. State Mus. Rep. 51. 



•'PILEUS 2-5 cm. broad, convex or nearly plane, glabrous, tough, 

 flexible, often somewhat irregularly uneven, dull brownish red or 

 dingy bay, more or less striate on margin. FLESH thin. GILLS 

 rounded behind, nearly free, narrow, subdistant, whitish or creamy- 

 yellow, becoming darker on drying. STEM 4-8 cm. long, 2-4 mm. 

 thick, slender, equal, tough, inserted, solid, reddish-brown above, 

 blackish-brown below, everywhere clothed with a grayish down or 

 tomentum, which is commonly a little more dense near the base. 

 SPORES 10 x 4.5 micr. (Pennington.) TASTE of dry plant bitter." 



On the ground in mixed woods. New Richmond, Ann Arbor. 

 August-September. 



This is apparently a variety of the preceding, if that species is 

 distinct, and not of M. peronatus us Ellis considered it. It is prob- 

 able that all three run into each other. The description is that of 

 Peck. Our plants had a bitter taste when fresh, otherwise not very 

 different from .1/. urens Fr. Glatfelter (Trans. Acad. Sci. St. Louis, 

 Vol. 16) gives spores 6-8x4-5 micr. which agree with those of 

 1/. urens.
