On the ground, under an open shed at Battersea. Aug.^Sowerbi/. 



Sowerby's plant is referred by Fries to I), latissima ; it is, however, 



of a pink hue and apparently much thinner, though, perhaps. Fries 

 uses the term ''• crassa'' merely by way of contrast with the neighbour- 

 ing species. 



6. PoLYPORUs. 3Iick. Polyporus. 

 Hymenium concrete with the substance of the pileus, consist- 

 ing of subrotund pores with thin simple dissepiments — Name ; 

 ^o?.jc, many, and 'jtoooc, ^ pore, in allusion to the numerous 2?ore5 

 of the Hymenium. 



* Pores large, angular. 

 1. P. Urdus, Berk. {Furze Polyporus) ; pileu? of a tough 

 elastic fleshy substance convex or subdepressed, at first slightly- 

 scaly, margin fibrilloso-squamose, pores large roundish or sub- 

 <][uadrate decurrent, stem central pilose or furfuraceous. 



On living Ulex Europeans. Sept. 1832. Beeston, Notts. Bev. 

 M J. BevMey. — Pileus \\ inch broad, convex or slightly depressed, 

 at first furfuraceo-squamulose, reddish-brown, at length nearly smooth 

 ochraceous, the margin fibrilloso-squamose, of a tough fleshy substance. 

 Pores large, rather "deep, decurrent, roundish or subquadrate, at first 

 white, the^edees slightly toothed and powdered with the white oblong 

 sporules. S}em \—\ inch high, f of an inch thick, central, covered 

 v;ith pores to the "very base, only the lower ones are abortive and their 

 interstices pilose or distinctly furfuraceous, nearly of the colour of t^he 

 pileus.— A very elegant and distinct fungus, and quite unlike any with 

 which I am acquainted, resembling somewhat in habit certain species 

 of Fries' subgenus Lentinus.

Decayed trunks of trees, stum|)s, &c., especially on Ash. Sum- 

 mer and early autumn, very common. — Solitary or imbricated. From 

 a subglobose or turgid scaly blackish knob arise one or more stems, 

 which are at first slightly compressed, flat, and hollowed out above where 

 they are furfuraceous; gradually the depressed surface expands but 

 more rapidly in the direcdon of the light and the hymenium is formed 

 beneath the small scales of the upper part of the stem, consisting when 

 fully developed of large angular pores becoming mere reticulations 

 towards the base. Pileus when fully expanded pallid-ochraceous with 

 scattered brown adpressed scales. Sporules oblong, white. If a portion
