CRYPTOGAMIA-FUNGI. H5 



2. T. ullida, whitish or light vinous-brown, soft and gelatinous, 

 in roundish, smooth, and somewhat lobed masses. WITH. iv. 83. 

 Knff. Sot. t. 2117. HOOK. Scot. ii. 31. GREV. FL Edin. 427. 



Hab. On stumps of rotten and moss-grown trees in dean-s, 

 not uncommon. 



The masses are about the size of a hazel-nut, semipellucid, 

 and in drying almost entirely disappear. 



3. T. spiculosa, blackish-green, effuse, plane, and rather thick, 

 minutely papillary on both sides PERS. Syn. 624. MOUG. and 

 NEST., No. 395. Exidia glandulosa, Sot. Gall. ii. 732. 



Hab. On decaying branches, not common. Spring. 



This originates under the bark, which it bursts through, and 

 then spreads over the branch for an inch or two in oval 

 patches, not adherent to the wood, but closely laid upon it. 

 It is black, thin, and firm when dry, but in a moist and 

 perfect state the colour is an olive-green, and the consist- 

 ence gelatinous although tough. The surface is even or 

 nearly so, covered on both sides with numerous small pa- 

 pillary tubercles or spiculae. The interior is transparent 

 and colourless. Botanists have usually quoted the Tre- 

 mella arborea of the Eng. Sot. as synonymous with this spe- 

 cies of PERSOON, but of the correctness of that I have some 

 doubt, for our specimens, which are precisely similar to 

 those in MOUGEOT and NESTLER'S collection, agree neither 

 with the figure nor description of the former. And, in- 

 deed, I am satisfied that at least -one other species has 

 been confounded with T. arborea, but I must leave the 

 task of establishing it to some better mycologist. 



4. T. sarcoides, erect, reddish-purple, at first club-shaped, then 

 rounded, lobed, plaited or curled, finally blackish WITH. iv. 84. 

 Enq. Sot. t. 2450. HOOK. Scot. ii. 32. GREV. FL Edin. 427- 



Hab. On rotten wood in damp woods, in winter and 

 spring. 



u Its substance is semipellucid, gelatinous, with a toughish 

 elastic skin ; the colour a vinous or flesh-like purple, turn* 

 ing dull, and at last black, in decay," SMITH.
