 Ragley. Mrs. Rnj]\ir(l. Inverary. Klotzsch, in Hooh. lIcriK On beech. 

 King's Clifle, Nortlis. On Tilia parvifolid. — Very nuich tufted, 

 fc^everal stuns are confluent in such a way as to nuike it doubtful whether 

 the several jtilci arc really distinct, or only lobes of one large one, 

 the circle of gills being always incomi)lete o\\ the side of tlie common 

 centre, the whole forming a lobcd lunnel with dtllected edges. The 

 surface is rough with j)rominent minute ribs or i)rickles, (as eNpresseil 

 in Swwerby's figure), pale rufesceut, often powdered with tiie N\hite 

 .spcrules, 1 — 1 ^i inch broad. Sometimes the surface is more even, but 

 Ktill somewhat sc ulptured so as to be rough with raised lines. Stem 

 compound strongly ribbed ami sulcate, tlie ribs being continuations of 

 tile serrated paler decurrent gills. At first the pileus and gills arc 

 tender ; stem firm and leathery. Odour agreeable. — There is a great 

 resemblance between this species and A. vnljtinus, Now. ; the principal 

 difference consisting in the one being absolutely without a .stem ami 

 horizontal, and the other being decidedly stijjitate ami more or less 

 erect.
