Sirobasidium magnum

Sirobasidium magnum is a species of fungus in the order Tremellales. Basidiocarps (fruit bodies) are gelatinous, lobed to foliose (leaf-like) and appear to be parasitic on ascomycetous fungi on wood. No other Sirobasidium species has such large fruit bodies. The species was originally described from Indonesia, but has been reported from elsewhere in Asia and also in Australia and North America.
