106 Journal of the Mitchell Society [December 



Notes by Bcardslee follow: 



Cap 0.5 cm. to 2 cm. broad, rounded convex, at times slightly raised ' 

 at the center, becoming more expanded with age and somewhat de- 

 pressed, hygrophanous, pale brown or brownish-olive, paler when dry, 

 and becoming opaque, and with a slight silky luster, margin thin, 

 striatulate when moist, even when dry; flesh thin. 



Stem slender, Aveak, 3-6 cm. long, a little lighter in color than the 

 cap, attached by abundant white mycelium to the mosses in which 

 the plant grows, smooth, and hollow. 



Gills grayish brown, rather distant, adnate, rather narrow, venous 

 connected. 



Spores elliptic, 7-9 by 4-5 [x. 



Odorless when fresh, but developing a slight disagreeable odor. 

 Growing in beds of sphagnum. 



This interesting plant was found in abundance in Sweden in 1905. 

 I have since seen it in similar places in Maine. When first found it 

 could not be determined with certainty, though its abundance in one 

 of Fries' collecting grounds indicated that it could not have escaped 

 him, especially as it is more than usually striking. Lange's excellent 

 notes on Collybia made it possible to identify it as above. Schroeter 

 has an excellent description as Lange points out in Pilze Schlesiens, 

 page 642, which exactly fits our plant. Fries' description does not 

 fit as well. Cooke's figure is not a good representation of our plant. 

 Ricken's description presents some difficulties. There seems little 

 doubt that our plant is C. clusilis in the sense of Lange and Schroeter. 



As it occurred in Sweden good opportunities for studying it were 

 given. Successive crops of specimens appeared after rains in the same 

 moss patches and its variations could be observed. The shape of the 

 cap seemed to vary considerably. What seemed to be the typical form 

 uniformly showed a slight umbo, or papilla. Other plants were 

 rounded or even depressed at the center, though scarcely so as to be 

 called umbilicate. The type material of Mycena palustris (Pk.) Sacc. 

 has been carefully compared with our specimens and found to be iden- 

 tical, though the description seems to indicate a discrepancy in regard 

 to the gills. 



1532. In a thick, dense bed of a large moss (Dicranum scoparium), woods south of 

 cemetery, December 4, 1913. It has also appeared in a similar bed of 

 the same moss near the sphagnum bed east of athletic field.
