Rev. M. J. Berkeley on the Flora of Van Diemen's Land. 323 



Gregarious, minute, dirty white, pruinose. Pileus membra- 

 naceous, reniform; stem distinct, lateral; alveoli roundish 

 4 — 6-sided. 



3. Polyporus (Favolus) vesparius, n. s. Pileus 2 — 3^ inches 

 across, 1 — 1J broad, 1^ inch high, stemless, subungulate, 

 sometimes imbricated, smooth or slightly scabrous, wood- 

 coloured, slightly zoned towards the margin ; flesh browner, 

 corky but soft. Pores very large, £ — J of an inch in diameter, 

 5 — 6 -sided, of the same colour as the pileus. 



On bark, Mr. Gunn. 



(3. corticosus. This variety appears at first sight very di- 

 stinct, but amongst the specimens sent is one which unites 

 the two forms. The pileus is grey, obliquely ungulate, rugose 

 and cracked, and resembles the bark so much that it would 

 scarcely be discerned did not the hymenium project beyond 

 the margin. 



4. Polyporus (Mesopus) rudis, n. s. Stem \ — 2\ inches 

 high, nearly central, rooting into the wood, even, brown, co- 

 vered with coffee-coloured bloom, shining when rubbed. Pi- 

 leus 3^ — 4J inches broad, convex, not at all depressed in the 

 centre, orbicular, brown like the stem, and covered with coffee- 

 coloured bloom or very minutely velvety, rugged, wrinkled as 

 if from the contraction of the flesh ; margin obtuse. Pores 

 brown, nearly orbicular, middle-sized. Substance light, pale, 

 soft and spongy. 



On rotten wood, Mr. Gunn. Its nearest ally is probably 

 P. rugosus, which has however extremely minute pores. 



5. P. lucidus, Fr. 



6. P.frondosus, Fr. The specimens are not in a good state, 

 but they are apparently referable to this species. 



7. P. sulphur eus, Fr. Mr. Gunn. 



8. P. velutinus, Fr. Thicker than the usual state, but ac- 

 cording w T ith specimens from Mougeot. 



9. P. [Ap. Coriacei) radiatorrugosus, n. s. Densely imbri- 

 cated. Pilei 2\ inches across, horizontal, rather thin, at length 

 smooth, radiato-rugose, dirty white or grey. Flesh white, 

 fibroso-coriaceous, but rather brittle. Tubes longer than the 

 flesh, middle-sized, white within, irregular ; orifice often jagged. 

 Resembling some states of P. versicolor, but certainly distinct.
