250 FLORA OF TASMANIA. [ Fungi, by M. J. Berkeley. 
9. Lentinus pulvinulus (Berk.); resupinatus vel vertice affixus, pulvinatus, pileo pallido glabro 
margine sulcato, lamellis latis ochroleucis integris. (Tas. CLXXXI. Fig. 10.) 
Has. On dead wood, Archer. 
About 3-1 inch across or resupinate, laterally attached, remarkably convex, smooth, ochraceous ; margin sulcate. . 
Gills very broad, yellowish, farinaceous ; edge entire.—There are but three individuals of this very interesting 
species, and those not very perfect, but they show that it is guite distinct from anything that has hitherto been 
published in this beautiful group.—PrATE CLXXXI. Fig. 10; a, plant, naf. size; b, vertical section. 
There are two indifferent specimens in the Tasmanian collections of an obscure, smooth Lentinus, with an even 
stem, which is possibly undescribed, but I have not sufficient materials to draw up a good character. 
Gen. IX. PANUS, Fr. 
Carnoso-coriaceus, tenax, arescens. Lamelle perfect, tenaces, inzequales, acie acuta integerrima, trama 
distineta fibrosa in hymenium radiante. 
Distinguished from Zentinus by its fibrous trama, and the entire edge of the gills. (Name from panus, a web; 
in allusion to the nature of the trama.) 
l. Panus saccharinus (Berk.) ; pileo reniformi horizontali subcarnoso, stipite brevi furfuraceo vel 
obsoleto, lamellis margine glanduloso-appendiculatis. 
Has. On dead wood, Archer, 
From 3-1 inch across, reniform, somewhat fleshy, wrinkled when dry, either entirely sessile or springing from 
a short furfuraceous stem. Gills moderately broad; edge glandular, as if dusted with sugar. The tint varies from 
ochraceous to lateritious.— This species is closely allied to Panus stypticus, but appears to be truly distinct. The 
gills are broader, and the pileus, though not smooth, is by no means broken up into furfuraceous scales. 
Gen. X. XEROTUS, Pr. 
Hymenophorum cum stipite contiguum, descendens in tramam cum pileo coriaceo-membranaceo tenui 
homogeneum. Zamelle integre, obtuse, coriacex. 
A most beautiful genus, resembling Cantharellus, but differing in substance, and in the broad gills of the more 
typical species. (Name from Enpos, dry.) 
1. Xerotus Archeri (Berk.) ; pileo reniformi minutissime ruguloso sulcato rufo, stipite brevissimo, 
margine deflexo, lamellis umbrino-brunneis inzqualibus simplicibus latiusculis distantibus paucis interstitiis 
levibus. (Tas. CLXXXIL Fig. 1.) 
Has. On dead sticks, etc., Archer, 
Pileus $ inch broad, red-brown, in parts paler, very minutely wrinkled, sulcate, smooth, at first furfuraceous ; 
margin waved. Stem very short, lateral, pulverulent. Gills few, simple, moderately broad, waved, with shorter 
ones intermixed, brownish ; interstices even.—Closely allied to X. discolor, which however differs in the absence 
of a stem, the more simple gills, ete. I have the same species from Chili.—Prate CLXXXII. Fig. 1; a, plant 
of nat, size, 
2. Xerotus Papyraceus (Berk.) ; papyraceus, pileo. pallido striato 1. levi tenuj, margine demum 
expanso, lamellis simplicibus fuscis |. pallidis. (Tas. CLXXXII. Fig. 2.) 
Has. On dead wood, J. D. H., Archer. 
Subimbricated, thin, pallid, at first convex, 3 inch broad, striate; margin expanded. Stem very short or ob- 
solete, Gills brown, simple, more numerous than in the last species,—This is very distinct, but its characters are
