TREMELLA (Dill.) Fr. 
(L., tremo, I tremble.) 
“Receptacle gelatinous or waxy, soft; foliaceous, brain-like or tubercular. 
Hymenium spread .over the whole surface, very rarely papillate. Basidia 
amphigenous, superficial or immersed. Conidia on. the same receptacle, preceding 
or^ accompanying the spores. Spores white, rarely yellowish; globose, oval, 
elliptical or pyriform; snuooth or punctate; jiroducing sporidiola on germination 
or tufts of conidia that bud in a yeast-like manner. Hyphae filamentous, thin, 
gelatinous, sometimes inclosing mineral concretions which form an irregular 
central nucleus. Growing on wood, rarely on the gr ound. ’ ’ — Rea. 
The species of Tremclla are firm-gelatinous and ofterr lobed so as to suggest 
the convolutions of the brain (cerebrifornr). The large orange Tremella 
mesenterioa is common. 
I. Foliaceous, divided up into lobes and variouslv twisted. 
548. Tremella frondosa Fr. (L., f rondonus, leafy). — “ Basidiocarp large (l.^in. 
(4 cm.) in extent in specimen sent, when soaked), foliose, firnr gelatinous when 
soaked and rich brown in colour (Pecarr Brown to Ver-onn Bi'own of Ridgway) 
drying blackish brown; lobes rather thin, fertile over entire exposed surface. 
Basidia yellow-brown, becoming divided into four cells by longitudinal or oblique 
septa, each cell pr oducing an epibasidiurn and spor-e. Basidiospores pale yellowish- 
brown to nearly colourless (probably ochraceous in mass), subglobose to broadly 
ovate, 7 to 8x5 to 7 g. ’’ — Martin. Soutlr Australia — Mount Lofty. Europe, etc. 
J uly. 
Professor Martin considers that this Australiarr plant would be considered as 
Phaeotreinella pseudof oliacea Rea by that author but that apparently all gi'ada- 
tions can be fourrd between Rea’s species and Tremella frmidosa aird T. f oliacea. 
II. Br-ain-like, with obtuse and twisted veins. 
549. Tremella mesenterica (Retz.) Fr. (Gr., mesos, middle; enteron, the 
intestine). — “Receptacle • to d.iin. (1 to 8 cm.), variously contorted, brain-like, 
plicato-undulate, gyrose, pruitrose witli the spores, orange. Flesh gelatinous, 
becoming firm, tough, concolorous. Spores broadly' elliptical, white, 14 to 14 x 
7 to 8 /r; ‘basidia 15 to 20 x 12 to 18 /r; corridia ovoid globose, 4 to 5 hyphae 
2 to 4 ’ — Board, et Galz. Dead branches, sticks and rails.’’ — Rea. South 
Australia — Ca])ucine Orange (in.), rich apricot orange. On dead branches of 
almond, Beaumont; on deacl parts of wild rose. Mount Lofty; Glen Osmond Road; 
Waterfall Gully'; Belair; Encounter Bay' district ; Monarto South; Berri. Queens- 
land. New’ South Wales. Victoria. Western Australia. Europe, etc. January, 
May to October. 
111. Crustaceous, effused, smooth. 
No South Australian species recorded. 
IV. Tubercular, small, suberunrpent. 
No South Australian species recorded. 
V. With a firm, hard nucleus. 
No South Australian sjiecies recorded. 
PHAEOTREMELLA Rea. 
(Gr., phaios, dark; tremella, the genus Tremella.) 
“Same characters as Tremella but the spores dark coloured.’’ — Rea. 
See No. 548, Tremella frondo.'ia, 
SEISMOSARCA Cooke, emended Martin. 
(Gr., .^eismos, a shaking, the sliock of an eartliquake; sarx, .sarlro.s', flesh.) 
“Fructifications cerebriform or lobed, tough gelatinous, becoming soft only 
after prolonged soaking. Gloeocystidia abundant, filled with yellow granular 
material. Basidia becoming longitudinally' septate, each segment producing an 
epibasidiurn. Basiiliospores short cylindrical or suballantoid, germinating by' 
repetition.’’ — Martin.
