8 22 THE AGARICACEAE OP MICHIGAN 



found covered with hyaline hairs, 50-60 niicr. long. The gills are 

 narrow and deeply decurrent, running up the inside of the unex- 

 panded cap and down below it on the stem. The cap often becomes 

 top-shaped instead of cucullate. Stevenson (British Fungi) and 

 Massee (Fungus Flora) say the gills are broad, a statement which 

 is clearly an error.

 Epicrisis, 1836 (as var. of 0. fibula).

PILEUS 4-7 mm. broad, rather firm, soon campanulate, obtuse 

 or at first umbonate, at length slightly umbilicate, even or striatu- 

 late, subpruinose, whitish with a slight fuscous tinge, disk fuscous- 

 brownish, FLESH thin, pale fuscous. GILLS adnate-decurrent 

 to strongly decurrent, arcuate, moderately broad, subdistant, whit- 

 ish. STEM 2-3 cm. long, filiform, hollow, equal, pallid below,. 

 tinged violaceous above, pruinose, even. SPORES oblong-elliptical, 

 5-6x2.5-3 micr., smooth, white. CYSTIDIA on sides and edge of 

 gills, scattered, subventricose, subcapitate at apex, some cylindri- 

 cal above, 40-45 x 9-12 micr. 



Gregarious on moss (Mnium, etc.) in hemlock woods. New Rich- 

 mond. June. Infrequent. 



O. schwartzii is constantly distinct from O. fibula to which Fries 

 joined it as a variety. Peck (45th Rep. N. Y. State Mus.) considered 

 it an independent species. Patouillard (Tab. Analyt.) had already 

 pointed out that it was distinct from Bulliard's O. fibula, giving 

 figures of spores and cystidia as evidence. It seems to be limited 

 to regions of coniferous forests. 



882. Omphalia fibuloides Pk. 

 N. Y. State Mus. Rep. 24, 1872. 



"PILEUS 1-2 cm. broad, convex, deeply umbilicate, glabrous, 

 hygrophanous. dull orange and striatulate when moist, paler when 

 dry. FLESH thin. GILLS strongly decurrent, arcuate, rather 

 close, white, the interspaces venose. STEM 3-5 cm. long, scarcely 

 2 mm. thick, equal, glabrous, hollow, colored nearly like the pilens. 

 SPORES elliptical, 7.5x5 micr."
