LACHNEA. 317 



On the ground. 



Distinguished by the bright yellow colour, and the rough 

 spores. The epispore is described as asperate by Cooke and 

 Phillips, but when carefully examined it is seen to consist of 

 very minute, depressed areas or polygonal pits, or in other 

 words there is a raised reticulation spread over the surface, 

 and enclosing irregularly polygonal areas, 



Specimen determined by ] >r. Mougeot, and now in Herb. 

 Berk., accepted as typical. This is the specimen figured by 

 Cooke in Mycographia, fig. 143.

Cups 2^ lines broad ; at first obovate or subcylindrical, 

 concave, and expanded, when mature of a bright orange-
