Armillaria hinnulea is a species of mushroom found only in Australia and New Zealand. It is a secondary pathogen (i.e., causing disease only after a primary pathogen has damaged the host) of wet native forests. It appears first as an immature mushroom with a rounded blackish rough cap and a thick white stalk. The stalk is covered with white fibres and is bulbous at the base. A fine cortina (cobweb-like partial veil) extends from the cap margins to the stipe.
Mature specimens of Armillaria hinnulea have flattened brown to olive-green caps with a dark granular material on the centres. Gills and stripes are a pale cream.
