VIII. On some new Fungi. By the Rev. M. J. BERKELEY, M.A., F.L.S. 
Read May 5th, 1857. 
Å VERY valuable collection of Fungi E been lately made by Fendler in Venezuela, 
which are now in the hands of the Rev. M. A. Curtis of South Carolina, and will shortly 
be offered for sale. The collection abounds in new species, of which I have selected three 
as peculiarly interesting, with the intention of bringing one or two more under the notice 
of the Society at some future meeting. To these I have added a description of a new 
species of Mitremyces from South Carolina, and of a very curious genus of Hypogæous 
Fungi lately received from Tasmania, with many other good things, through the kindness 
of Mr. Archer. The Tasmanian collection will shortly be described in Dr. Hooker’s Tas- 
manian Flora, but this genus is so curious that it deserves previously a more especial 
notice. 
1. HyDNUM BRUNNEOLEUCUM, Berk. & Curt. Pileo flabelliformi : ne tenui luteo- 
brunneo glabro; hymenio pallido setulis validis consperso. * 
On dead wood. Venezuela (Fendler). : 
Pileus thin, flabelliform, vaulted, 13 inch long, nearly as much broad, yellowish-brown, 
smooth, slightly streaked behind. Hymenium whitish, sprinkled with many scattered 
strong bristles. 
This species is closely allied to Sy dd flavum, Berk. (Peziza flava, Swartz), a figure 
of which was published in the Annals of Nat. Hist. vol. x., from an original specimen in 
the British Museum. It occurs in Venezuela as well as Jamaica, and is no. 129 of - 
Fendler's collection. It differs from the present species not only in colour, but in the 
bristles being divided above. Both belong to Fries’ genus Kneiffia, but its characters 
` scarcely separate it with sufficient precision from Hydnum. H. brunneoleucum is exactly 
a Kneiffia, but then Hydnum luteum, which is clearly congeneric, approaches so closely 
to Hydnum, that I know not how to separate it. The two species have a Tag Peziza- 
like habit which at once distinguishes them from all others. - 
2. ORATERELLUS PAPYRACEUS, Berk. & Curt. Pileo centrali tellisin umbilicato cocci- 
neo glabro; stipite gracili karer fusco ; ed lævi ochraceo. 
Venezuela (Fendler). : 
Pileus 3$ inches across, extremely thin, umbilicate or very broadly Bifundibuliform, 
smooth, slightly fissured at the margin which is arched, bright scarlet, with a few vein- 
like peneilings in the umbilicus; stem 4 inches high, not a line thick, smooth, reddish- 
brown, equal except at the very base, where it is slightly dilated as it springs from the 
‘matted mycelium. Hymenium quite smooth, pee
