194 THE AGARICACEAE OF MICHIGAN 



PILEUS 1.54 cm. broad* convex with obtuse umbo, finally tur- 

 binate and plane to depressed, hygrophanous, with, a thin, separable, 

 subviscid pellicle, even or at length pellucid-striate, glabrous, livid 

 rufescent then brownish- flesh color, margin soon spreading. 

 FLESH thin except disk, rather fragile, concolor. GILLS decur- 

 rent from the first, distant, not broad, acuminate at ends, very 

 veiny, whitish, tinged grayish-brown, trama of interwoven hyphae. 

 STEM 3-6 cm. long, 3-6 mm. thick, equal or subequal, elastic, in- 

 nately fibrillose-striatulate, apex naked, stuffed or at length hollow, 

 whitish. SPORES broadly elliptical, smooth, 6-9x5-6 micr., white. 

 BASIDIA slender, 40 x micr., 4-sp'ored. < JYSTIDIA none. ODOR 

 none. TASTE mild. 



Gregarious or solitary. On the ground in mossy or grassy moist 

 places, in low woods or edge of swamps. Ann Arbor, New Rich- 

 mond. Infrequent. 



Bresadola gives a good figure, though our plants average smaller 

 than his. It has the shape of H. pratensis but is hygrophanous and 

 thinner, and must not be confused with the gray variety of that 

 species. It prefers springy or moist places. The entire lack of odor 

 separates it from //. foetens Phil, and H. peckianus Howe.

PILEUS 2-(! cm. broad, couvex-campanulate, then expanded- 

 plane to subdepressed, subturbinate, hygrophanous^, glabrous, 

 smoky-violaceous or smoky-lilac when fresh and moist, fading to 

 pale gray, with a thin gelatinous pellicle, subviscid when moist, soon 

 dry and shining, even. FLESH white, rather thin. GILLS arcuate- 

 adnate to decurrent, distant, not broad, intervenose, colored like 

 the pileus when moist, at length whitish or grayish-wdiite, trama of 

 interwoven hyphae. STEM 3-6 cm. long, 2-8 mm. thick, slender or 

 stout, equal or narrowed downwards, slightly fibrillose or glabrous. 

 apex naked, at first stuffed by a large soft pith which disappears, \ 

 at length hollow and easily splitting, white or pale silvery-gray. 

 SPORES ovate-subglolnose, smooth.. 5-6.5x4-5 micr. BASIDIA 

 short, 30x6-7 micr. ODOR none. TASTE mild.
