Elvela atra, Plor. Dan., pi. 634, fig. 1. 



In damp woods. 



Distinguished by the blackish colour of every part and 

 the furfuraceous stem. 



Specimen in Karst., Tung. Fenn. n. 446, examined. 



Eeadily distinguished by the small size, and more 

 especially by the scurfy-villose under surface of the pileus 

 and stem. The. British specimens collected by Berkeley 

 and figured by Cooke in Mycographia, fig. 169, are stouter 

 than the typical form, and have an olive-brown disc, but in 

 other respects are identical. The typical form has also 

 been collected in Yorkshire.
