mucli larger and thicker. Pores more or less yellow. In Sir 

 W. J. Hooker's Herbarium there is a curious stemless ungu- 

 late pitch black variety with brownish pores gathered in North 

 America by Dr. Scoulcr. Dr. Richardson also gathered an 

 extraordinary form at the Slave Lake on the white spruce 4£ 

 inches long, 7 inches broad, 2} 2 inches thick at the base, en- 

 tirely stemless, decurrent at the base, with a strongly raised 

 convex border. Surface veiny, varnished ; the older portions 

 dull and slightly cracked. Substance, hard, corky, pale, not 

 at all red. Pores very minute, dirty white. 



13. P. (Pleuropus) Amboinensis, Fr. Mauritius. Mr. Tel- 

 fair. Some states of this species approach so near to P. hir- 

 cidus that it is difficult sometimes to believe it distinct. There 

 are specimens in Sir W. J. Hooker's Herbarium almost ex- 

 actly intermediate. 



14. P. (Pleurojms) flabelliformis, Kl. I.e. Pileus rigid, thin, 

 obsoletely tomentose, zoned, tawny-bay, at length blackish ; 

 margin acute ; pores extremely minute, dirty white ; stem very 

 short. Pilei 2 — 4 inches broad, sometimes laterally connate, 

 flabelliform, coriaceous-rigid, elegantly zoned, the interstices 

 coarsely velvety, emarginate, plane or depressed, very variable 

 in colour, generally brown variegated with chestnut. Hyme- 

 nium pale tan. Pores perfectly round or elliptic. Stem ab- 

 ruptly black at the base, where it is sometimes dilated. 



Mauritius, where it appears to be a common species. Mr. 

 Telfair. Analogous to Pol. versicolor. 



15. P. [Merisma) discolor, Kl. 1. c. Imbricated, confluent, 

 subsessile. Pilei flabelliform, connate at the base, longitudi- 

 nally rugulose, plicate, lobed, dirty white ; pores brown-olive, 

 plane, extremely minute, subrotund, sometimes torn. Sub- 

 stance fleshy, white, when brittle old. Pilei irregular, lobed, 

 growing together at the base, longitudinally rugose, 3 — 6 

 inches broad. 



On trunks of trees. Mauritius. Mr. Telfair. 



16. P. {Merisma) Telfairii, Kl. 1, c. p. 484. Imbricated, 

 confluent, sessile; pilei minutely tuberculoso-rugose, obso- 

 letely zoned, white, subpubescent ; pores minute, plane, some- 

 what toothed, of the same colour. Substance carnoso-coria- 

 ceous. Pilei subpubescent, sometimes sericeo-striate and shi-
