Cups about 2J lines broad. This appears at first as 

 a minute, hairy Chetomium-like body, nearly black, after- 

 wards expanding into a sublentiform disc. The brown 

 hairs of the hymenium, being prolongations of the para- 

 physes, give this plant a striking character. 



Name — Acus, a needle, colo, to inhabit ; on pine- 

 needles.
