GENUS XLI. Kneiffia (after Kneif, a promising mycologist Kneiffia. 

 of Baden, who died young). Fr. Gen. Hymen. 



Hymenium amphigenous, continuous, united, but incomplete 

 (imperfect), similar (to the hymeno- 

 phore), destitute of granules and 

 warts, strigose and roughened with 

 rigid, scattered or fasciculate bristles. 

 Sporophores single- spored ; spores 

 elliptic. Laxly fleshy, soft, when dry 

 collapsing and becoming flocculose. 

 Swelling out of chinks in the bark of 

 trees into 'various forms, hemispheri- 

 cal in its most perfect state. Fr. Hym. 

 Eur. p. 628. 



1. K. setigera Fr. Milk-white, 

 irregularly effused, thick, fleshy, un- 

 dulated, flocculose within, silky 

 beneath, beset with scattered hyaline 

 bristles. 



Of no constant form, but certainly a typical plant, not a degenerate con- 

 dition of any other, and the type of a most distinct genus, in its substance and 

 white colour comparable only with Corticium serum, but differing in the 

 fructification. The bristles are rigid, equal, not to be compared with those of 

 Aiiricularini. The largest specimens are of the size of an apple, but com- 

 monly thin, effused, often incrusting Sphcerice. 



On dead wood. Uncommon. April. 



Somewhat resembling Grandinia granulosa in general appearance. M.J.B. 

 Spores elliptic, 11-14 mk. B. r= Br. Name seta, a bristle ; gero, to carry.
