Tlate LIU of this Report. 



PILECS 3-10 cm. broad, convex then broadly campanulate, some- 

 times obtusely umbouate, finally plane, at first covered by a hairy 

 tomentum, then oppressed fibrillose-scaly, not striate, tawny to yel- 

 lowish, darker to umber on center, sometimes radially rugulose, 

 margin at first appendiculate from the veil, at length split. FLESH 

 thick on disk, soft, watery-brown to sordid yellowish. GILLS ad- 

 nate-seceding, broad behind but sinuate, narrowed toward front, 

 crowded, not reaching margin of pileus, at first pale yellowish then 

 innber and dotted by spore masses, edge white-flocculose, beaded 

 with drops. STEM 2-8 cm. long, variable in length, 4-10 mm. thick, 

 equal, soon hollow, fibrillose to floccose-scaly and tawny up to the 

 obsolete annulus, whitish above; veil soft-fibrillose, soon breaking, 

 dingy, white, remnants clinging to the margin of the pileus. 

 SPORES oval to broadly elliptical, 9-12x7 micr., tuberculatc, dark 

 purplish-umber under microscope. CYSTIDIA few or scattered on 

 sides of gills, cylindrical, in groups of several, about 00 x 9-10 micr., 

 abundant on edge, cylindrical-subcapitate, 45-55 x 0-7 micr. ODOR 

 and TASTE earthy. 



Caespitose, scattered or solitary on alluvial soil or swampy 

 grounds in woods. Throughout the State. July-October. Fre- 

 quent. 



This is the E. lachrymabundum Fr. of most authors. See notes 

 on the preceding. It is distinguished by its tawny or darker color, 

 very characteristic, tuberculate spores and cylindrical cystidia. 

 The gills usually distil drops from their edge in moist weather. 

 These drops are often dark colored from the spores, hence Fries
