REPORT OF THE STATE BOTANIST 6 1 



Collybia confluens Pers. 

 Confluent Collybia. 



(Ilyni. Eur. p. 1 1 7. Syl. vol. v. p. 222.) 



Pileus thin, tough, flaccid, convex or nearly plane, obtuse, rarely some- 

 what umbonate, glabrous, hygrophanous, reddish grayish-red or reddish- 

 brown and often striatulate on the margin when moist, pallid, whitish or 

 grayish when dry; lamellae narrow, crowded, free, whitish or yellowish- 

 gray; stem equal, cartilaginous, hollow, clothed with a short dense some- 

 what pulverulent whitish pubescence or downy tomentum; spores minute 

 ovate or subelliptical, slightly pointed at one end, .0002 to .00024 inch 

 long, .0001 to .00014 broad. 



Pileus 8 to 18 lines broad; stem 2 to 5 inches long, i to 2 lines thick. 



Among fallen leaves in woods. Common. July to October. 



The plants commonly grow in tufts, but sometimes in lines or arcs of 

 circles or scattered. They revive under the influence of moisture and 

 thereby indicate an intimate relationship to the genus Marasmius. The 

 pileus varies much in color, but commonly has a dull reddish or russety 

 tinge when moist, sometimes approaching bay- red. It fades in drying 

 and becomes almost white or grayish-white, but sometimes the center 

 remains more deeply colored than the margin. The stem is commonly 

 rather long in proportion to the width of the pileus. Occasionally it is 

 somewhat flattened either at the top or throughout its entire length. 

 Sometimes the stems become united at the base which union is sug- 

 gestive of the specific name. The spores are described in Sylloge as 

 "subglobose, 7-9 mm." In our plant they are as described above. 



Collybia Familia Pk. 



Family Collybia. 

 (Rep. 23, p. 79.) 



Pileus thin, rather fragile, convex or hemispherical, glabrous, somewhat 

 hygrophanous, often striatulate on the margin when moist, whitish, yel- 

 lowish-gray or brownish, sometimes darker or brown on the disk; lamellae 

 narrow, close, rounded at the inner extremity and almost free, white; 

 stem slender, glabrous or under a lens minutely pruinose-pubescent, 

 hollow, white or whitish, commonly with a white mycelioid villosity at 

 the base; spores globose, .00016 to .0002 inch broad. 



Plant densely ctespitose; pileus 6 to 12 lines broad; stem 2 to 4 inches 

 long, about i line thick.
