290 OUTLINES OF BRITISH FUNGOLOGY. 



Oil elder and elms. Very common. Our figure is from 

 specimens on elms which have the surface of the hymenium 

 freer from folds. I do not, however, consider it a distinct 

 species. 



48. N^MATELIA, Fr. 



Nucleus solid, heterogeneous, covered with a gelatinous 

 stratum, which is everywhere clothed with the hymenium. 



1 . N. eneephala, Fr. ; nearly sessile, pulvinate, plicato- 

 rugose, pale flesh-coloured, then brownish. — Willd. Bot. May. 

 i. t. 4. /. 14. 



On pine-rails. Rare. Loch Lomond, Wales, Mr. Ralfs. 

 Looks like the brain of some animal. Nucleus large, opaque, 

 white. 



2. N". nucleata, Fr. ; sessile, flat, somewhat gyrose, white, 

 then brownish-yellow. 



On rotten wood. Rare. Sometimes confounded with 

 Tremella albicla, from which it differs in the presence of a 

 small white nucleus. I see no difference between British and 

 American specimens. 



3. N. virescens, Cd. ; small, roundish, depressed, gyroso- 

 tuberculate, or quite even, green. — Fl. Dan. t. 1857,/. 1. 



On furze-branches. Common. 



49. DACRYMYCES, Nees. 



Homogeneous, gelatinous. Conidia disposed in moniliform 

 rows. Sporophorcs clavate, at length bifurcate. 



1. D. violaceus, F?-.; small, compact, somewhat compressed, 

 gyrose, \aolet. 



On trunks of pear-trees. Rare. Relhan. 



2. D. deliquescens, Dubi/ ; jjulvinate, slightly waved and 

 plicate, yellow.
