Var. .1. PILEUS L-2 cm. broad, conic-ovate then campanulate 

 <>r subhemispherical, obtuse, subviscid by a thin, separable pellicle, 

 hygrophanous, at first yellowish-gray ihin gray t<> fuscous, gla 

 brous, striate on the margin which is at first straight. GILLS 

 arcuate-adnexed, uncinate, rather broad, ventricose, subdistant. 

 whitish at first, grayish-rufescenl in age, edge entire. STEM In 

 cm. long, 2 mm. thick, yellowish or pellucid pale yellow, tough, 

 equal, straight <>r flexuous, tubular, sometimes twisted or com 

 pressed, viscid by n thin, separable pellicle, rooting. SPORES 



broadly elliptical, 9-10x6-6.5 mice, si >th, obtuse, white. 



CYSTIDIA aone. ODOR none or slightly farinaceous. BASIDIA 

 attenuated downward, clavatej to \ 6-7 micr., t-spored. 



On the ground in low, elm woods. Detroit. October. 



Form typical. This is a much inure slender-stemmed plant, de 

 scribed and illustrated by Atkinson and Sard. The pileus is elon 

 gated-conical al first and the stem filiform. The colors are similar 

 to Var. l. I have seen this form rather frequently in northern 

 Michigan, but have no notes on it. 



v.-ir. H. PILEUS 5-8 Dim. broad, obtusely conic-campanula te. 

 glabrous, with a viscid, separable, thin pellicle, obscurely striata- 

 late, grayish-brown. GILLS adnate-arcuate, uncinate, rather nar 

 row. subventricose, white, intervenose. STEM filiform, 3-8 cm. 

 long, 0.5 mm. thick, equal, i>isoid, flaccid, shining, glabrous, even, 

 pruinose at apex, pallid with brown tinge, rooting and mycelioid 

 at base. SPORES broadly elliptical, 8-9x5-6 micr., smooth, ob 



tuse, white. CYSTIDIA i •. BASIDIA about _J micr. long 



ODOR none or slightly nitrous. TASTE aone. 



Oe decorticated, half-decayed logs. Wu Richmond. Septem

Mycena epipterygia, like the following, is probably .i compoe 

 species, as Maire has pointed out. (Bull. Soc. Myi France, Vol 

 p. itin. i Fries placed a series of previously described species under 

 this one and considered the colors insufficient to differentiate them.
