Imbricata, coriaceo mollis, brunneo-purpurascens ; pileolis inaequa- 

 bilibus, rugosis, depresso-sericeis; hymen io sublsevi, pulverulento. 

 . Imbricated; pilei three quarters of an inch long, laterally con- 

 fluent, uneven, rugged, brown inclining to purple, with a pale margin, 

 of a soft coriaceous consistence; surface soft clothed with matted 

 down, not distinctly pubescent; zoneless; hymenium concave, nearly 

 even, not setulose; smell strong and unpleasant. One specimen, 

 gathered apparently in a different locality, consists of a mass of pilei 

 running one into the other with but little distinct hymenium. Allied 

 to T. terrestris. 



Thelephoka albo marginata, Schwein. Mss. — On bark of dead 

 buttonwood. Cincinnati, March 19, 1842. 



Latissime confluenti-effusa, rarius breviter reflexa, umbrina, centro 

 pruinosa, margine albo-tomentoso. 



At first consisting of distinct, orbicular patches, which soon be- 

 come confluent; umber, velvety, but by no means bristly, clothed with 

 a white bloom, in the centre quite even, or irregularly rugose, some- 

 times reflexed, in which case the pileus is brown and silky; margin 

 white, tomentose, not fimbriate. This was distributed under the name 

 of T. arida, but more perfect specimens show that it is a fine and very 

 distinct species. It is possible that T. albo-badia may be a S3 T nonym, 

 for I do not find the name adopted above from Sir W. J. Hooker's 

 Herbarium, in Schweinitz's list.

 1842.* 



Didtmicm regulosum, u. sp. — On bark of honey locust. Cincinnati, 

 June 27, 1842. 



Gregarium; peridio lenticulari, subtus late umbilicato, albo, rugu- 

 loso; stipite tenui costato, stramineo, apice attenuato, capillitio, parco, 

 albo; sporis nigris, sub lente fusco-purpureis. Columella nulla. — 

 Berk, in Hook. Lond. J~ourn., vol. iv., p. 308. 



A minute species, one third of a line in diameter, with the stem 

 two thirds of a line high. The appearance of the surface of the 

 peridium is like that of a little globule of the mother of vinegar, white 

 and curdled. 



Stemonitis fusca, Roth. — On dead poplar. Cincinnati, J uue 23, 1840.f 



* The specimens are remarkably fine, spreading for several feet over the uDder side of 

 dead logs. The pileus is concentrically zoned, of a rich brown, and decidedly tomentose. 

 The general appearance is somewhat different from European specimens, but I do not con- 

 sider it a distinct species. 



t Spores larger than in British specimens.
