About Gymnopilus allantopus (Berk.) Pegler
Gymnopilus allantopus is extremely common in the Perth region of Australia, where it grows most often on fallen logs and branches of Banksia species. This fungus produces its fruit bodies between May and July each year. It also grows large amounts of fan-shaped white mycelium inside the wood of infected trees, which is visible at any time of the year. Gymnopilus allantopus can be easily identified in the field by several features: its bright gills that develop rusty-colored spots as they age, a white flap on the edge of young caps, and its characteristic white fan-like mycelium. It produces a bright ochre brown spore print. In most cases, its fruit bodies have a straight stem. However, when specimens grow out from the side of a log, the stem curves upward as a result of geotropism.
