THE AGARICACEAE OF MICHIGAN 



3.5 cm. long, thickened at the base where it is spongy and fulvous- 

 hairy, elsewhere furfuraceus-pulverulent." SPORES 7-9 x 3-4 micr. 

 (Morgan); 4-5x3 micr. (Glatfelter). 



Reported by Longyear, as under oak trees among grass. Also 

 said to grow among fallen leaves, and around stumps in rich soil. 



I have not seen it 



Section II. Tergini. STEM tubular, rooting, cartilaginous. 

 , Pileus hygrophanous. Gills seceding. 



*Stem glabrous except the mycelioid-hairy base.

33. Marasmius glabellus Pk. 

 N. Y. State Mus. Rep. 26, 1874. 



PILEUS 1-2 cm. broad, convex-expanded, obtuse, often distantly 

 striate, dingy ochraceous, uneven on disk. FLESH membranaceus. 

 GILLS adnate-seceding, broad, distant, ventricose, white or whit- 

 ish, intervenose. STEM 2-5 cm. long, 0.6-1 mm. thick, slender, 

 equal, homy, tubular, glabrous, shining, whitish at apex, reddish 

 brown or chestnut elsewhere, mycelioid-thickened at base. SPORES 

 (10x4.5 micr., from one of Peck's collections). 



Var. bellipes={M. bellipes Morg.) Jour, of Myc, Vol. XI, 1905. 



PILEUS pale tawny-brown to pink-purplish, distantly sulcate or 

 plicate, subpapillate, glabrous or minutely velvety. STEM with di- 

 lated apex, varymg above from whitish to bright wine-purple wr 

 pink. SPORES elliptical oval, curved-apiculate, 10-12x4-5.5 micr., 

 smooth, white. BASIDIA 30-42x6 micr., slender. ODOR and 

 TASTE none. (Otherwise like M. glabellus.) 



Gregarious or' scattered, among fallen leaves on the ground in 

 frondose woods. Ann Arbor. August-September. Infrequent. 



As no authentic spore-measurements are published, it is impos- 

 sible to say whether M. bellipes is entirely distinct. The latter, 

 however, seems to be the form that occurs in our region. Inas- 

 much as the plant, as it occurs here, varies considerably in color, it 

 would not be surprising if Peck's species had the colors men- 

 tioned for both. The variety is a beautiful plant when in the fresh 

 state, due to the highly colored stem. M. pulcherripes Pk. differs 

 from the latter apparently only in its narrow gills and very filiform 

 stem ; the spore-size is not given.
