Splitgill Mushroom

Physical Characteristics

Caps are small, typically 1-4 cm wide, fan-shaped or shell-shaped, whitish to grayish, often hairy or fuzzy, and attached directly to the substrate without a distinct stem. The underside features distinctive 'split gills' which are gill-like folds that split longitudinally down the middle when dry and close over unfavorable conditions to protect the spores.

Habitat & Growing Conditions

This mushroom is a common wood-rotting fungus, found on dead wood of various deciduous and coniferous trees. It is often found on stumps, logs, and branches. It can be found globally, making it one of the most widespread mushroom species.

Season & Fruiting Time

It can be found year-round in various climates, as its fruiting bodies are quite resilient and can dry out and rehydrate multiple times to release spores. Most commonly observed during moist periods.

Similar Looking Species

Due to its distinctive 'split gills', there are few species that are easily confused with Schizophyllum commune. Some other small, shelf-like fungi might be superficially similar, but none possess the unique longitudinally split gills.

Ecological Role

Schizophyllum commune is a saprophytic fungus, meaning it plays a crucial role in the decomposition of dead wood. By breaking down lignin and cellulose, it helps recycle nutrients back into the ecosystem.
