Metacampanella

Metacampanella R.H. Petersen 2024, in Petersen & Hughes, Mycology, 8 (2024).

Etymology: Morphology and molecular biology close to Campanella, but distinct.

Diagnosis: Basidiomata conchate, obcupulate to obsaucer-shaped, up to 20 mm broad, sessile, pseudostipitate or laterally stipitate, flexible and rubbery when young, becoming gelatinous in maturity; pileus surface matt, white to suffused greenish or blue-greenish (rarely pale pink); hymenophore usually of some radial rounded veins, usually developing few to numerous interveins, meandering or joining the major veins. Pileipellis a thatch of slender hyphae, often encrusted with annular thickenings and sometimes mixed with tetrapyrgoid pileocystidia; pleurocystidia fusiform; basidia (2-)4-spored; spores hyaline, thin-walled, generally triangular in shape, sometimes with abaxial bulge; cheilocystidia missing, tetrapyrgoid or metuloid, with or without crystalline deposit. Fruiting on dead woody substrates, monocot including bamboo, grass, sedge or rush, or uncommonly on dicot rotting wood. Clamp connections are apparently ubiquitous. ITS sequence analysis indicates inclusion with Tetrapyrgos and Campanella, but separate from both.
