ceptibl^ to the attacks of insects or snails and are usually almost 

 entirely eaten away before maturity. 



Stem up to 6 cm. long, often bent at the base, in our plants usually 

 fused with others into a solid basal mass, sometimes nearly equal 

 above the base, again strongly expanding near the cap; when not 

 fused with others the individual stems are usually decidedly swollen 

 or bulbous below, but base not enlarged in the fused stems except 

 as they expand into the mass ; surface smooth, generally with ridges 

 and grooves, almost silky-shining, dull or sordid white; flesh rather 

 fragile, fibrous, solid, but softer-fibrous inside. 



Spores white, short elliptic, lateral apiculus at one end, smooth, 

 4-5.4 X 5.4-6.8^. 



In Chapel Hill this species grows only in ashes, usualb^ where 

 piles of trash have been burned, a fact I have not seen mentioned by 

 others. 



Cooke's illustration of C. tumulosa (pi. 105) and Schaeffer's of A. 

 multiformis (pi. 14) leave little doubt that their figures repre- 

 sent our plant. This is also true of Bresadola's pi. 32 in Fungi Tri- 

 dentini, published as C. conglohata but later said by him in a letter 

 to Beardslee to represent C. cinerascens. Clitocybe fumosa Fr. is lighter 

 in color and has a more expanded cap. Peck's C. multiceps might 

 well be this, but is described and figured (Bull. N. Y. St. Mus. 139: 

 pi. 117) as being much whiter, and photos by Kauffman (Agaricaceae 

 of Michigan, pi. 157) and Clark and Kantor (Mycologia 3: pi. 52. 

 1911) show a denser mass of plants. From these interpretations it 

 would seem that C. multiceps is nearer C. conglohata than C. tumulosa, 

 if indeed the two latter are really different. Ricken considers them, 

 as well as Tricholoma pcs-caprae Fr., the same. Gillet's pi. 689 under 

 the last name is just like our Chapel Hill plant. Clitocybe tnulti- 

 formis Pk. does not seem to be different from C. multiceps (see 

 Mycologia 7: pi. 164. 1915). 



Beardslee agrees that our Chapel Hill plants are C. tumulosa and 

 that C. multiceps Pk. is the same. He believes that C. conglobata is 

 different and we are giving his notes and photographs of this species 

 as he understands it.
