285. Thelephorafastidiosa,Yi\ Bristol, H. 0. Stephens, Esq. ; 

 near the Box Tunnel, C. E. Broome, Esq. 



Distinguishable at once by its abominable odour, which remains 

 for a long time in dried specimens. I have never myself met 

 with it. 



286. T. mollissima, P. Syn. p. 572 ; Berk. Brit. Fung, no.245. 

 Merisma cristatum, yar.fusco-badium, Desm. ! no. 362. Extremely 

 common in the Northamptonshire woods, running over moss, 

 small sticks, &c. 



I have seen precisely the same species gathered by Delastre in 

 the south of France. The plant published by Desmazieres is just 

 the same. I have found a specimen of this growing freely from 

 a central stem and assuming the form of Thel. palmata. 



287. Corticium arachnoideum, n. s. Totum effusum niveum, 

 molle tenerrimum mycelio latissime-serpente arachnoideo, hyme- 

 nio Isevi glaberrimo. Creeping over mosses and lichens on fallen 

 sticks, Northamptonshire. 



Forming delicate effused arachnoid patches of a snowy white ; 

 threads by no means forming fibres, but spreading like a delicate 

 web, and often remaining barren, but under favourable circum- 

 stances giving rise to a smooth even hymenium, consisting of 

 elliptic sporophores arranged in little bunches. I have not yet 

 seen perfect spores. The species appears to me undescribed, and 

 is very distinct from all with which I am acquainted. Its habit 

 is not unlike that of Thel. hombycina. The genera Thelephora and 

 Corticium, it may be observed, are very far from being completely 

 settled. The character upon which Fries mainly relies, of endo- 

 sporous and exosporous fructifying cells, is manifestly untenable, 

 as all species with endosporous asci must be removed from Hy- 

 menomycetes.

 nified. 



288. C. velutinum, Fr. Lambley, Notts, Bev. M. J. Berke- 

 ley; Linlithgowshire, C. E. Bauchop, Esq. 



A very elegant species of a pale pink, remarkable for its floc- 

 cose mycelium, and the delicate pile with which the whole of the 

 hymenium is clothed, giving it a velvety appearance. 



289. Cyphella griseo -pallida, Weinm. Fl. Ross. p. 522. Mi- 

 nima, primo granuliformis demum elongata erecta cupulseformis 

 stipite brevissimo basi fibris brevibus strigosulis albis affixa, de- 

 mum dependens subintegra, extus floccosa, hymenio Isevi pallide 

 gilvo. On hard gravel where discoloured with minute algae, 

 Apethorpe, Jan., Rev. M. J. Berkeley. 



Whole plant one-third of a line in diameter, at first granu- 

 liform, then regularly cup-shaped, with a short stem and attached 

 by a few radiating, white, substrigose, short threads, at length de-
