together; stem slender, subtomentose, fawn-coloured, with

 On trunks of trees. Mauritius. Mr, Telfair. 



5. L. exUis, Kl. MSS. in Hook. Herb. Pileus thin, of a 

 tough fleshy substance, smooth, ochraceous-tawny; gills equal, 

 decurrent, distinct, entire ; stem even, smooth. Pil. 2 — 4 

 inches broad, margin lobed. Gills crowded. Stem ^ an inch 

 high ; 3 — 4 lines thick. 



On rotten wood. Mauritius. Mr, Telfair. 



Favolus. 



1. F, (Pleuropus) Humboldtii, Berk. Stem short, lateral, 

 gradually expanding into the thin, obovate, somewhat lobed, 

 smooth, tawny, pileus ; alveoli small, elongated, of the same 

 colour as the pileus ; dissepiments thin. Pileus with the stem 

 Ij inch long, l|^inch broad, with three rounded lobes. Stem 

 not i an inch long. 



The specimen from which the above character is drawn up 

 is clearly a Favolus, but it is unfortunately not in a good state of 

 preservation. It is marked in Sir W. J. Hooker's Herbarium, 

 Humb. No. 179. The alveoli are far smaller than in either of 

 the two following species, to which it is closely allied. In form 

 and colour it is much like Favolus braziliensis, Fr., which how- 

 ever differs in several respects. From F. flaccidus it differs in 

 being stipitate, and from F, tenuicaulis in not being reniform. 



2. F, {Pleuropus) hepaticus, Kl. in Linn, vol. Vii. p. 197. 

 Of a tough fleshy substance ; pileus reniform, Hver-coloured, 

 smooth, lobed in free-growing specimens ; stem extremely 

 short, lateral ; alveoli 6 — 4-angled, elongated, dirty white ; dis- 

 sepiments very thin. Favolus canadensis and Polyporus cel- 

 lulosus, Kl. in Hook. Herb. 



Solitary, variable but more or less reniform. The colour of 

 the pileus is darker towards the base. Pil. 2 — 5 inches broad, 

 1 1 — 3 inches long, smooth. Stem very short, 3 lines thick.
