216 FUNGI. [Tremella. 



point, in the accounts of Smith and Chevallier, I cannot help regarding 

 them as having the same production in view. Chevallier describes his 

 plant as " lisse^' while Smith's is finely pubescent or granulated. In 

 every other respect they agree, especially in not communicating any 

 colour to water in which they are macerated. Fries has taken no 

 notice of either, so far as I can discover, even in his latest publication. 



4. T, mesenterica, Retz. (^orange Treinella) ; rather tough 

 twisted lobed and plicate orange-yellow. Retz, in Vet, Act,

On branches, sticks, &c. ; all the year. Frequent. — Varying con- 

 .siderably in size and form ; sometimes quite flat and thin, but generally 

 ascending and strongly lobed and plicate; when full grown, consisting 

 of branched easily discernible filaments, towards the apices of which is 

 a dense stratum of roundish very minute sporides. — A small round 

 discoid Tremella occurs not unfrequently in the hollow stumps of 

 felled trees, which has the same curved sporidla as are figured in 2V. 

 albida, Eng. Bot.. with a few smaller round ones interspersed ; but 

 Avhether contained within the larger ones at first or not, I am unable 

 to say. I have found the same production on Furze, a plant on which 

 T. mesenterica abounds. This I suppose must prove the var. disci- 

 formis, Fr. If not an early stage of 2\ mesenterica, which, however, 

 it can scarcely be, it must be considered as distinct. I have not at 

 present an opportunity of sufficient investigation of the subject, and in 

 no division of Fungi is it less desirable to publish new species with 

 vague characters, than in that of TremclUni. 



5. T, cerehrina, Bull, (brain-like Tremella); tough undu- 

 lated somewliat gyrose dirty-white. Bull, t, 386. Fr. Syst. 

 Myc. V. 2, p. 215. 



On dead wood, branches, &c. Winter and spring. Much more 

 uncommon than the following species. — I feel certain that the plant 

 figured by Bulliard is quite distinct from that of Smith in Fiig. Bot. 

 It is much more compact in its mode of growth, exactly resembling the 

 brain of some animal, of a tougher substance, and, if I mistake not, 

 though I do not lay particular stress at present upon the circunistance, 

 the sporidia instead of being curved like those of Tr. albida, are 

 broadly elliptic or subglobose, with a distinct narrow border. It 

 has generally a more or less decided red tinge. T. albida. Smith, 

 A\-hich is probably the plant intended by Hudson, is fiir less complicated 

 in its mode of growth and is of a tender consistence ; its sporidia, 

 which are strongly curved, exactly resemble those o^ Exidia glandulosa^ 

 and I have once observed distinct obovate or subglobose asci. 



6. T. albida, Smith, (dirty-ivhite Tremella); tender sessile 

 dilated slightly lobed and waved the edges obtuse, sporidia 

 oblong curved. Eng. Bot. t. 2117. Huds. p. 565 ? 



On fallen trees, branches, &c. Winter and Spring ; very commorr. 



" It bursts through cracks in the bark and then spreads itself in 



horizontal or clustered, rounded, obtuse, scolloped masses, white, semi- 

 pellucid, extremely gelatinous and tender when young ; afterwards 

 turning yellowish." Sm. I. c. The above description exactly accords
