juniperina of Linnaeus. I found it growing' plentifully on the living 
main stem of the Juniperus communis in the same wet seasons as the 
above. Dr. Smith in E. Bot. justly observes, that most parasitical cryp- 
togamous plants are found either upon totally dead trunks or branches, 
which is the case with Fungi or Tremellae in general; or they are rooted, 
like the crustaceous Lichens, in decayed external layers of the bark. On 
the contrary, the T. sahince and T.juniperina spring from the live wood, 
under the bark of vigorous branches. From these circumstances Dr. 
Smith infers these plants to be mere gummy exudations, and that the 
powdery surface is owing to resinous particles, insoluble in water, 
accompanying them.” But I have been so fortunate as to find both 
these kinds of Tremella in perfection at the same time, have proved them 
to be totally insoluble in water, and that their substance is ho more of a 
gummy nature than that of many other of the same Genus, particularly 
T. mesenteric a. 
Common on the junipers at the Larches. April. E.) 
Tr. deliques'cens. Deliquescent: yellow, changing to orange red; 
sessile, lobed : lobes few, blunt. 
( Grev. Scot. Crypt,. 159. E.)— Bull. 455. 3. 
(Fructifying in every part. E.) In clusters; each plant about one-tenth 
of an inch over. (Most of the species of this genus, at their first appear¬ 
ance, are soft and jelly-like. On the contrary, T. deliquescens is firmest 
in its early state, becoming soft and gelatinous as it verges towards 
maturity. Purton.

plaits.

On dead branches of trees. Gelatinous, tremulous, pellucid, smeared 
with a viscid moisture : white when young, changing to yellow. Horny 
when dry ; growing in irregular patches. Jacq. Golden yellow, changing 
to tawny when old; variously plaited and wreathed. SchaefF. iv. p. 108. 
(From dried specimens Mr. Purton has observed to spring forth long 
golden hairs, Clavaria-like, which he suspects may prove a parasitical 
fungus. E.)

(Tr. ferrugin'ea. Sessile, clustered, lobed, waved, of a rusty brown ; 
the surface finely pubescent. 
E. Bot. 1452. 
Substance gelatinous, pliable, tender, becoming thin, shrivelled, and shape¬ 
less when dry ; reviving, though imperfectly, on a re-application of mois¬ 
ture. Segments obtuse, lobed and waved, but not so plaited or sinuous 
as those of T. mesenterica ; neither is the surface, as in that, smooth, but 
finely granulated; the granulations pale, giving the plant a velvet-like 
gloss, with brown irregular specks, perhaps fructification, among them. 
Internal substance white. E. Bot.
