'"T^HE root confifts of a few imperceptible fibres, which irr- 

 finuate themfelves into the fubftance of fuch decayed ve-» 

 getable matter, as afford proper nourifhment to the plant. 



The ftem is one or two inches high, hard, black, and 

 fhining ; from the thicknefs of a horfe's hair to that of a large 

 hog's briftle, either of which, in fubftance and in touch, it not 

 unaptly imitates. It often remains for a confiderable time after" 

 the pileus is fallen. 



The gills are few, narrow, and remote ; they are of a pale 

 duhky white, while the plant is young, but change to brown 

 afterwards. 



The pileus is at firff conical, and white, afterwards fpreads, 

 becomes almoft horizontal, and about half an inch in diameter; 

 the colour changes to brown, pale near the margin, darker in 

 the centre ; it is fometimes lfriated and conftantly of a thin, 

 dry, membraneous fubffance. In decay it withers and falls off". 



Grows on putrid leaves, chiefly thofe of oak, in the fhady 

 moift parts of woods about Halifax; it alfo grows on moors, 

 among rufhes. I faw it in great abundance, in September, this 

 year 1787, on the hill above Caufey-Foot, near Halifax ; it grew 

 upon the ffalks of decayed rufhes, in the place where the 

 Trientalis europcea, and the Ophrys cordata grow.
