Elvela atra, Flor. Dan., pi. 534, fig. 1. 



In damp woods. 



Distinguished by the blackish colour of every part and 

 the furfuraceous stem. 



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



Readily distinguished by the small size, and more 

 esjoecially 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.

Pileus 2-3-lobed, bent down and often saddle-shaped, thin, 

 bistre or greyish, under surface greyish and scurfy-villose, 

 1-2 cm. across ; stem 1-2 cm. high, thin, stuffed, even, firm 

 and elastic, scurfy-villose, greyish ; hypothecium and ex- 

 cipulum formed of thin, hyaline, interwoven hyphae which 

 become pteudoparenchymatous at the cortex, and run out 

 into groups of clavate, septate hyphae forming the scurfy 

 exterior; asci cylindrical, apex rounded, 8-spored; spores 

 obliquely 1-seriate, hyaline, smooth, continuous, broadly 

 ellij^tical, ends obtuse, 1-guttulate, 16-18 x 10 ft; para-
