5. Xerotus Berterii, Mont. ! (non X. Bertierii) = " Pez. ner- 

 vosa concava hemisphaerica atropurpurea ; habitat in densis- 

 simis sylvis Malaccae." Konig in Herb. Mus. Brit. 



Dr. Montagne remarks to me in a letter lately received, 

 speaking of Lentinus Berterii, that Fries has unfortunately 

 changed the name Berterii into Bertierii. He writes that this 

 is the more important, as there is a French surgeon at Bour- 

 bon named Bertier who is a mycologist.

This species appears to be common in Guiana from the 

 quantity of specimens brought by Dr. Schomburgk. The 

 name is calculated to mislead, as the pileus is in fact scarcely 

 at all striate. Swartz's specific name probably referred to the 

 obsolete zones. This and another nearly allied species from 

 Guiana resemble much Lenzites abietina. I shall hope to de- 

 scribe both in an account of the Fungi collected by Schom- 

 burgk which are now in the herbarium of Sir W. J. Hooker. 



8. Pol.Agariceus (Konig sub Boleto). Pileo e lento coriaceo 

 convexo umbilicato azono glaberrimo ; margine involuto de- 

 mum subnudo ; stipite centrali subelongato flexuoso deorsum 

 velutino ; poris submagnis subhexagonis decurrentibus. "Bot. 

 agariceus, Fl. Zeyl. in nemorosis," Kbn. in Herb. Mus. Brit. 



Ceylon, Konig. Herb. Mus. Brit. 



Pileus 1 inch broad, quite smooth, convex, umbilicated ; 

 margin more or less involute, obscurely ciliated. Stem 1^ — 

 1^ inch long, ^ — 1 line thick, flexuous, rather thickened above, 

 where it is nearly smooth, velvety below. Pores radiating, 

 subhexagonal, elongated, yg-th of an inch broad, decurrent ; 

 dissepiments thin, acute. 



Allied to Pol. arcularius and P. tricholoma, but abundantly 

 distinct. In an early stage of growth the cilia are probably 

 more visible. 



9. Polyporus sacer, Fr. Pileo tenui rigidiusculo orbiculari 

 profunde umbilicato zonato, fusco rufoque variegato glabres- 

 cente, radiatim striato. Stipite centrali radicato fulvo-brunneo, 

 sursum attenuato velutino ; hymenio pallido a stipite omnino 

 distincto ; poris mediis subhexagonis. 



Herb. Mus. Brit., without habitat. 



Pileus 4 inches across, rather deeply umbilicate, thin, but 

 rather rigid, orbicular, beautifully zoned, and variegated with 

 shades of deep brown and red ; at first minutely velvety, 

 marked in a radiating direction with striae. Stem 6 inches 

 high, about half an inch thick, hard, white within, attenuated
