without regard to the color of the pileus or lamellje, for this seemed to 

 me to be a much more simple and natural classification. 



I.amellie brownish-lilac myriadophylla. 



LamelliTS yellow or yellowish, changing to brownish-red in drying . colorea, 



Lamelliis having neither of the above characters i

4 Pileus dark-brown when moist, lilac-brown when dry fuscolilacina.

CoUybia myriadophylla Pk. 



Many-leaved Collybia. 

 (Rep. 25, p. 75.) 



Pileus very thin, broadly convex plane or centrally depressed, some- 

 times umbiHcate, hygrophanous. brown when moist, pale ochraceous or 

 tan-color when dry ; lamellae very numerous, narrow, linear, crowded, 

 rounded behind or slightly adnexed, brownish-lilac ; stem slender, but 

 commonly short, equal, glabrous, stuffed or hollow, reddish-brown ; spores 

 minute, broadly elliptical, .00012 to .00016 inch long, .00008 broad. 



Plant scattered or somewhat casspitose; pileus 8 to 12 lines broad; 

 stem I to 1.5 inches long, about half a line thick. 



Decaying wood and mossy humus in woods. Not rare. July to 

 September. 



This is a small but very distinct species by reason of the peculiar color 

 of the lamellae. In the dried specimens these assume a more brownish- 

 red hue, as in the next following species. They sometimes appear to 

 have a glaucous reflection, probably from the abundance of the spores. 

 The stem is generally more or less radicated and often slightly floccose- 

 pruinose toward the base. The basidia are very short, being only .0006 



to .0008 inch long. 



CoUybia colorea Pk. 



Colored Collybia. 



(Rep. 26, p. 54) 



Pileus thin, convex or nearly plane, obtuse or subumbilicate, subglab- 



rous, hygrophanous, yellow or yellow tinged with red, the margin usually 



shghtly surpassing the lamellae ; lamellae rather close, narrow, emarginate, 



adnexed, yellow or yellowish, changing to brownish-red in drying ; stem
