repeatedly but not strongly zoned, slightly undulated and un- 

 even ; edge very thin and acute ; substance of the colour and 

 consistence of cork. Pores large, y-g-th — ^th of an inch broad ; 

 dissepiments rather thin, acute, often torn and elongated be- 

 hind, very shallow towards the margin, wood-coloured like the 

 pileus. The pileus does not shine, but though of a different 

 colour has somewhat the aspect of that of Hexagona tenuis. 

 It resembles Dccdalea tenuis, but is much more zoned, and 

 the dissepiments are much thinner.

 (Scenidium) fVightii, Kl. in Linn. vii. p. 200. Boletus Favus, L. 

 Ins. Ind. Or., A. Dalrymple, Esq. Herb. Mus. Brit. 



Hexagona tenuis is marked in the Linnaean Herbarium 

 Boletus Favus, but not by Linnaeus, with whose description 

 it does not correspond. The name is evidently not authentic. 



30. Hexagona Kbnigii, n. s. Pileo suberoso-coriaceo sub- 

 reniformi subazono piano fibroso-setoso gilvo-badio ; alveolis 

 irregularibus amplis, dissepimentis elongatis subflaccidis setu- 

 losis. 



Ceylon, Konig. Herb. Mus. Brit. 



Pileus 3 inches broad, 2\ long, thin, subero so-coriaceous, 

 subreniform, from a distinct but not stipitiform vertex, very 

 obscurely zoned, deep red-brown, rugose, clothed with scat- 

 tered branched rigid bristles, which at length fall off, leaving 

 a raised line ; substance ferruginous, velvety, like that of Pol. 

 foment arius -, alveoli large, nearly a line broad, very irregular; 

 dissepiments thick, not rigid, elongated and toothed, paler 

 than the pileus, deep setulose within. 



This species is very nearly allied to Hexagona Wightii, dif- 

 fering principally in the irregular elongated pores with flaccid, 

 not rigid, dissepiments. The pores are so little hexagonal, 

 that were it not for the very evident affinity, it might be placed 

 in the genus Dcedalea. 



31. Hexagona papyracea, n. s. Pileo sessili semi-orbiculari, 

 papyraceo, tenui, flexili, subtiliter velutino glabrescente cre- 

 bri-zonato sanguineo-lignicolorique variegato; hymenio cer- 

 vino; poris hexagonis regularibus mediis. 



Herb. Mus. Brit. Hab. unknown. 



Pileus 9 inches broad, 5 inches long, sessile, semiorbicular, 

 thin as paper and very flexible, marked with little raised ra- 

 diating striae, repeatedly zoned with intermediate finer lines, 

 variegated with sanguineous and ligneous shades, at first 

 clothed with extremely fine olive-brown velvety down, like a 

 coat of some Cladosporium ; edge extremely acute, of a more 

 tawny tinge than the rest of the pileus ; substance bright 

 fawn-coloured, silky. Hymenium fawn-coloured ; pores hex-
