This species is founded on material sent from Maine by 

 Mr. F. L. Harvey. Professor Harvey, upon the authority of 

 Mr. Morgan of Ohio, quotes the species, Bull. Tor. Bot. Club, 

 24, 67, as B. vcrna (Somm.) Rost. But the specimens cer- 

 tainly do not conform to description of B. verna as given by 

 Fries, Syst. Myc., III., 146, or Rostafinski, Mon., p. 145. Fries 

 describes the peridium as properly white; fuscous, black only 

 because of the contained spores. Here the wall corresponds 

 with what is seen in B. rubiginosa. In fact the present spe- 

 cies resembles, suggests, a large sessile form of B. rubiginosa; 

 but the spores are much larger, and the capillitial structure 

 very different. Rostafinski's description and notes suggest 

 the propriety of Lister's disposition of B. verna (Somm.) Rost., 

 i.e. combination with B. panic ea. 



Rare. On mossy logs, Maine.

 1875. Badhamia lilacina (Fries) Rost., Mon., p. 145. 

 1892. Crater mm lilacinum Mass., Man., p. 271. 



Sporangia globose, sub-globose, or obconical, sessile, gregari- 

 ous or more or less clustered, supported by a thin continuous 

 transparent hypothallus ; the peridium smooth pale lilac brown 

 without, white within; stipe none, although some sporangia 

 have a narrowed base ; columella none, the pseudo-columella 

 formed by a more densely aggregated capillitium near the 

 base ; capillitium dense, white, strongly nodulose ; spore-mass 

 black ; spores dark violaceous brown by transmitted light, dis- 

 tinctly warted, or reticulate, the reticulations resembling some- 

 what those of some of the Tric/iias, as T. affinis, 10-15 A 6 - 



Easily recognizable generally at sight by its peculiar color. 

 White forms, however, occur, often lilac tinted and white from 

 the same plasmodium. A perfectly white colony seems to be
