 slenderly filiform. 



Peziza dematiicola — B. and Br., "Ann. Nat. Hist.," 

 No. 1070, t. 15, f. 20; Cooke, " Handbk.," No. 2117. 



On dead wood, nestling amongst the flocci of some 

 Helminthosporoid fungus, but whether at all related or 

 not we cannot say. This very beautiful, though minute, 

 species has a mixed resemblance to an Excipula and 

 such Ascoboli as A. ciliatus (B. and Br., I. a). 



Cups 100 to 500^t broad. It is not merely ciliated, 

 but clothed with delicate hyaline hairs. The cups when 

 old are applanate, extremely thin, having a raised margin. 



Name — Dematium, a genus of Hyjphomycetes, colo, to 

 inhabit. 



Herb. Berkeley ! Sutton Coldfield, near Birmingham !
