Analysis of the Genera. 



* Basidia subglohose, longitudinally quadripartite in a cruciate manner at 

 maturity, and producitig at the apex jour elongated sterigmata. 



61. ExiDiA, Clip-shaped or variously lobed ; spores sausage-shaped, 



curved ; sterile surface minutely velvety. 



62. Tremella. Brain-like or variously lobed and contorted ; spores 



globose or ovoid. 



63. N^MATELiA. Firm, convex, with a central firm nucleus. 



** Basidia cylindrical or clavate, divided at the apex into two long sterigmata. 



64. Dacryomyces. Small, pulvinate. gyrose. 



65. GuEPiNiA. Irregularly cup-shaped or flabellate ; hymenium on one 



surface only, the other sterile and silky. 



66. Calocera. Erect, simple or branched, subcylindrical. 



*** Basidia elongated or fvsoid, transversely septate, each cell prodncing 



one spore. 



67. AuRicuLARiA. Broadly attached, effuso-reflexed, upper surface sterile 



and strigose. 



68. HiRNEOLA. Cartilaginous, human-ear shaped, attached by a narrow 



point, sterile surface minutely velvety. 



69. Septobasidiu:\i. Resupinate, not gelatinous but leathery. 



61. Exidia, Fries. 

 Inflated, tremelloid, marginate or vaguely effused, often minutely 



papillose, black or dusky. 



Exidia, Fries, Syst. Myc, ii, p. 224. 



Forming irregular subgelatinous masses on dead wood and 

 branches. The spores become 1-many septate on germination, 

 each cell of the spore giving origin to a very short promycelium, 

 bearing a cluster of strongly curved sporidiola. 



Exidia alhida, Bref., Unters. MykoL, vii., p. 94, pi. v, fig. 14 ; 



Sacc, Syll. vi. no. 8352 ; Austr. Fung., p. 207. Syn., Tre- 

 mella alhida, Huds. 



Gelatinous, bursting through cracks in bark and wood, under 

 the form of wavy or contorted heaps 1-3 cm. across ; white at 

 first, soon becoming ding}^-yellow or brown ; when mature prim- 

 rose, with the dense mass of spores resting ou the surface ; spores 

 oblong, sUghtly curved, 16-20 x 5-7 ix. 



On dead branches, &c. New Zealand. Australia, Tasmania, 

 Europe, United States. 



Very soft and gelatinous, form irregularly lobed, soon de- 

 liquescing. 



62. Tremella, Dili. 

 Gelatinous, tremelloid, immarginate, generally smooth (not 



papillose nor rugulose), variously lobed and contorted, often 



bright-coloured. 



Tremella, Dill, Hist. Muse, p. 41. 



Forming foliaceous variously contorted gelatinous masses
