REPORT OF THE STATE BOTANIST 5 1 



In size and shape this fungus resembles Collybia dryop/iila, but its color, 

 which closely resembles that of Lactarius lignyotus, is far different. It 

 has been found but once. It is apparently related to C. phwopodia, but 

 has no umbo and no fuscous tint to flesh pileus or stem. 



CoUybia butyracea Bull. 

 Buttery Collybia. 



(Hym. Eur. p. 113. Syl. vol. v. p. 209.) 



Pileus fleshy, thin, convex becoming expanded, umbonate, smooth, 

 redciish-brovvn, becoming paler with age, moist in wet weather, flesh dingy 

 or whitish when moist, white when dry ; lamellae thin, crowded, crenulate, \ 

 adnexed or almost free, white ; stem commonly tapering upward, glabrous, 

 striate, reddish or reddish-brown, usually with a white tomentum on the 

 thickened base, white within and stuffed or hollow; spores elliptical, 

 .00024 to .0003 inch long, .00012 to .00016 broad. 



Pileus 1.5 to 3 inches broad; stem 1.5 to 3 inches long, 2 to 3 lines 

 thick at the top, thicker at the base. 



Woods in hilly and mountainous regions. Not rare. June to October. 



The umbonate pileus, slightly uneven or crenulate edge of the lamellae 

 and the more distinctly striate and upwardly tapering stem serve to 

 separate this species from C. dryophila. It grows especially under or 

 near coniferous trees. 



Collybia maculata A of S. 



Spotted Collybia. 

 (Hym. Eur. p. 112. Syl. vol. v. p. 207.) 



Pileus fleshy, firm, convex or nearly plane, even, glabrous, white or 

 whitish, sometimes varied with reddish spots or stains, flesh white; lam- 

 ellae narrow, crowded, adnexed, sometimes nearly or quite free, white or 

 whitish; stem generally stout, firm, equal or slightly swollen in the middle 

 striate, white, commonly narrowed at the base and praemorsely radicating, 

 often curved at the base, rarely slightly thickened and blunt; spores sub- 

 globose, .00016 to .00024 inch broad, sometimes showing a slight 

 apiculus at one end. 



Pileus 2 to 4 inches broad; stem 2 to 4 inches long, 3 to 6 lines thick. 



Woods. Catskill and Adirondack mountains. July to September. 



Var. immaculata Cke. This differs from the type in having no reddish 

 spots or stains. 



This species is easily recognized by its large size, firm or compact sub- 

 stance and white color. It grows in soil filled with decaying vegetable 

 matter or on much decayed wood.
