130 REV. M. J. BERKELEY ON SOME NEW FUNGI. 



This very beautiful Fungus, whicli is remarkable in the genus Craterellus for its 

 elegant habit and extremely thin pileus, is conspicuous from the beautiful red of the 

 pileus, resembling that of fading leaves of Ampelopsis quinquefoUa. It is altogether one 

 of the most charming species mth which I am acquainted. 



3. Skeppebia, nov. gen. (Tab. XXV. A.) 



Stipes brevis, lateralis, in pileum tenuem utrinque arete convolatum clavulamque obtusam referentem 

 abrupte transiens ; pileus externe cellulosus intus filamentosus. — Genus Stereo affine, Edtnundo 

 Skeppero plantarum Cryptogamicarum solerti indagatori dicatum. 



S. CONVOLUTA, Berk. & Curt. 



On dead sticks, Venezuela {Fendler, no. 286). 



About 1 line high. Stem rising from a little orbicular disk | of a line high, but con- 

 fluent for some distance with the pileu.s and rather paler ; pileus f of a line high, of a 

 deep vinous brown, sprinkled with little heaps of granules arising from the breaking up 

 of the outer coat, strongly convolute on either side, so as to form a little compact clavate 

 body with a deep groove on one side like that of a grain of wheat, composed externally of 

 cells, internally of filaments which give rise to the hymenium. Hymenium pale, studded 

 with cystidia. 



This singular Pungus looks at first sight Kke a little Mitrula, with which genus it 

 may be confounded if the microscopical structure is neglected. The outer surface, how- 

 ever, is covered with little heaps of granules consisting of a number of deeply coloiu'ed 

 cells, beneath which smaller cells occur, which pass into branched threads, and these into 

 an even hymenium consisting of closely packed sporophores with projecting cysticha. 



Few genera are more singular in their characters. Notwithstanding the resemblance 

 of Pistillaria, there is no close aifinity. Skepperia will come next to Stereum, without 

 however passing into it by any intermediate forms. 



4. MiTBEMYCES Bavenelii, Berk. (Tab. XXV. B.) Pusillus ; peridio exteriori in ver- 

 rucas parvas Uberas vel cohserentes dehiscente ; interiori glabro ; intimo conformi, 

 nee spatio magno vacuo cu'cumdato ; sporis eUipticis ; ostiolo miniato. 

 On the ground. Caesar's Head, Mountains of South Carolina [H. W. Ravenel, Esq.). 



Rather more than ^ an inch high, including the stem. Stem shoi-t, consisting of intricate 

 mucedinous threads. Outer peridium cracking up into warts of various sizes, which are 

 sometimes scattered, but sometimes adhere together so as to form a little lid. Inner 

 peridium smooth, pale, terminated with a few triangular vermilion-colom-ed teeth ; inmost 

 delicate, entirely filling the cavity of the second peridium ; flocci abundant, white, ter- 

 minated with little racemes of obtuse processes ; spores ovate, •z^to'o i^ich long, not 

 granulated. 



Very distinct from aU the other species in the larger size of the inmost peridium. The 

 nearest aUy is Mitremyces Junghuhnii, figured in the ' Botanische Zeitung ' for 1844, 

 which has the teeth of the ostioJum pale, and the spores globose.
