DEMERARA FUNGI. 
The following is an enumeration of a collection of Fungi from 
Demerara, recently exposed at the Forestry Exhibition at Edin- 
burgh, and now transferred to the Royal Herbarium at Kew : — 
Lentinus velutinus, Fr. 
Lenzites applanata, Fr. 
Polyporus (Mesopus) rugosus, Fees. 
Polyporus (IVIesopus) pansus, Berk. 
It seems almost impossible to indicate any line of separation 
between P. pansus, B., and P. camerarius , B. 
Polyporus (Pleuropus) flabelliformis, K. — Large form, with the 
stem nearly obsolete. 
Polyporus,. Pleuropus) lucidus, Fr.

Polyporus (Fomes) ligneus, Berk. 
Polyporus (Fomes) fraxineus, Fr. 
Polyporus (Fomes) marmoratus, Berk. — This is the same as the 
Polyporus fasciatus (Fries), of the Kew Herbarium, but not the 
Polyporus fasciatus (Fr.) of the Berkeley Herbarium. 
Polyporus (XVIerismoidei) senex, Fees. 
Polyporus (Fomes) ?

identify. 
Polyporus (Fomes) sulcatus, Cooke. 
Pileo durissimo, convexo-plano, reniforme, glabro, opaco, umbrino, 
concentrice dense profundoque sulcato, cute crasso indurato ; con- 
textu albo, fuligineo maculato ; tubulis abbreviatis, stratosis, albi- 
dis ; poris rotundatis, minutis, albis, dissepimentis crassiusculis. 
Hymenio convexo, margine sterili. 
On trunks. Demerara. 
Pileus 6-9 inches across, l^in. thick behind, gradually attenuated

Polyporus (Fomes) geotropus, Cke. 
Pileo suberoso-lignoso, durissimo, incrustato, concentrice sulcato, 
radiato-rugoso, postice subtuberculoso, glabrato, pallido ; margine

large coarse specimens of P. auberianus , M. in habit, but more 
friable, and very subject to the attack of insects.
