So THE AGARICACEAE OF MICHIGAN 



titious. SPORES lanceolate, 6-8x2.5-3 micr., smooth, white. ODOR 

 none. 



Gregarious, attached to fallen leaves, twigs, pine needles, etc. 

 Houghton, New Richmond and probably throughout the state. 

 July-September. 



Not to be confused with M. perforans Fr. which has a similar ap- 

 pearance, but differs in possessing a strong, specific odor (not of gar- 

 lic), and in its minutely-velvety stem covering. 



54. Marasmius epiphyllus Fr. 

 Syst. Myc, 1821. 



Illustrations: Cooke, 111., PI. 1137. 

 Patouillard, Tab. Analyt., No. 219. 



PILEUS 2-8 mm. broad, convex, at length flattened and depressed 

 or subuinbilicate, subpruinose or glabrous, milk-white rugulose. 

 FLESH membranaceus. GILLS adnate, few, very distant, white. 

 STEM 14 cm. long, filiform, equal, reddish-broirn, paler or whitish 

 at apex, pruinose, pubescent toward base, instititious, tough. 

 SPORES narrowly fusiform-lanceolate, 9-12x34 micr., smooth, 

 white. CYSTIDIA moderately abundant, on sides and edge of gills, 

 10-50x7-8 micr., subacuminate, narrowly lanceolate. BASIDIA 30x7 

 micr., 4-spored. ODOR none. 



Gregarious, on fallen leaves of oak, etc., attached to midrib and 

 veins. Ann Arbor. October. 



Distinguished from the preceding by the pruinose stem. M. in- 

 stititious Fr. is said to differ by the sulcate-plicate pileus and the 

 thicker stem which tapers downward. The spore-sizes given by 

 various authors clash here as in many other cases. Massee and 

 Cooke give them as 3x2 micr. ; Morgan (ex Saccardo) as 6-7x2. Our 

 plants appear to be those of Ricken. 



55. Marasmius capillaris Morg. 

 Ann. Soc. of Nat. Hist. Jour., Vol. 6, 1883. 



PILEUS 2-6 mm. broad, convex, umbilicate, plicate-sulcate, alu- 

 taceus sometimes darker, with ivhite umbilicus, glabrous. FLESH 

 membranaceus. GILLS adnate to a free collar, moderately broad, 

 white, distant. STEM 3-5 cm. long, capillary, equal, long, black ; 

 scarcely whitish at very apex, glabrous-shining, tubular, tough,.
