Fam. VI. TREMELLINACEÆ
Entire fungus homogeneous, gelatinous, collapsing when dry,
retaining its form when moistened, traversed internally by branched
hyphæ which terminate in basidia at the periphery. Basidia variable
in form, elongate or fusoid, transversely septate or continuous,
undivided or forked at the apex, or subglobose and longitudinally
divided and bearing 2 to 4 sterigmata. Spores hyaline, from globose
to sausage-shaped and curved, continuous or septate, often becoming
variously septate on germination and producing sporidiola of different
forms. Species 2001—2041
