Tremella encephala

''Tremella encephala'' is a species of fungus producing pink, brain-like, gelatinous basidiocarps . It is widespread in north temperate regions and is parasitic on another species of fungus , that grows on dead attached and recently fallen branches of conifers.
Naematelia sp. Globular (lumpy) structures growing on a hardwood branch alongside Stereum sp. Texture is firm to slightly gelatinous. Interior is white.

Appearance

Fruit bodies are gelatinous, dull pale pink to yellowish pink, up to 3 cm across, and brain-like with a hard, whitish core when cut. Microscopically, the hyphae are clamped and occur in a dense gelatinous matrix. Haustorial cells arise on the hyphae, producing filaments that attach to and penetrate the unclamped hyphae of the host . The basidia are tremelloid , 13–20 by 12–17 μm, usually unstalked. The basidiospores are mostly roughly spherical in shape, smooth, 6–11 by 5.5–9 μm, and germinate by hyphal tube or by yeast cells.

Distribution

''Tremella encephala'' is a parasite of ''Stereum sanguinolentum'', growing on and often completely enveloping host basidiocarps. Following its host, fruit bodies are typically found on dead, attached or recently fallen branches of conifers.

The species has a north temperate distribution and is known throughout North America, Europe, and northern Asia. It has also been recorded from Australia.
