moist and often obscurely striatulate on the thin soon spreading 

 margin, white when dry, sometimes slightly colored in the center, 

 flesh white, taste mild ; lamellae thin, moderately close, adnate or 

 slightly decurrent, white or whitish; stem equal or slightly tapering 

 upward, stuffed, fibrillose-reticulate, whitish, often with a whitish 

 mycelioid tomentum at the base ; spores elliptic, .00024-.0003 of an 

 inch long, .00016-.0002 broad. 



The saucer clitocybe is gregarious and grows among fallen leaves 

 under alders and white birches, and occurs late in the season. Its 

 cap is 1-2 inches broad; its stem 1-1.5 inches long and 2-4 lines 

 thick. It is generally white throughout. In the character of the 

 stem the species is related to the cup shaped clitocybe, C. c y a t h i - 

 f o r m i s Fr., but in its white color, in its thin quickly expanding 

 margin, and closer gills it is more closely related to C. dealbata 

 Sow. The central depression of the cap is partly due to the eleva- 

 tion of the thin margin. The upper surface of the cap is therefore 

 concave or saucer shaped and does not become funnel form. The 

 margin is sometimes wavy or irregular. The small size and rarity 

 of the species detracts from its importance as an edible species, but 

 its agreeable flavor and harmless character make it worthy of a place 

 in our list of edible species.

 OAK LOVING COLLYBIA 



PLATE III, FIG. I-II 



Pileus thin, convex or nearly plane, sometimes depressed in the 

 center with the margin elevated and often wavy or irregular, 

 glabrous, obtuse, variable in color, pale alutaceous, yellowish, dark 

 tan or chestnut, flesh white; lamellae thin, close, narrow, rounded 

 behind, slightly adnexed or nearly free, white or whitish, rarely 

 tinged with yellow ; stem equal, thickened toward the base or bulb- 

 ous, glabrous, hollow, commonly colored like the pileus; spores 

 elliptic, .00024-.0003 of an Inch long, .00012-00016 broad. 



The oak loving collybia is one of our most common mushrooms. 

 It occurs in woods, groves, open places and pastures and appears at 

 any time from early spring to late autumn, when there is a sufficient 

 degree of warmth and moisture. A favorite place of growth for 

 it Is among fallen pine leaves or under pine trees. It also grows 

 on decaying wood. It may be solitary, gregarious or tufted. In 

 dense tufts the caps are usually very irregular on account of mutual
