Inocybe godeyi is a species of Inocybaceae fungus found in Europe. The species produces mushrooms with cone-shaped caps up to 5 cm (2 in) in diameter. The caps are cream, becoming browner, but they bruise red. The stem is up to 6 cm (2 in) long, and has a "bulb" at the base. The white flesh has a strong smell and an acrid taste. The mushrooms can be found on forest floors in autumn months; the species forms an ectomycorrhizal relationship to surrounding trees, favouring beech. I. godeyi is known to be poisonous, containing muscarine compounds, and consumption of the mushrooms can lead to SLUDGE syndrome. The species is sometimes mistaken for the deadly I. erubescens.

First described by Claude Casimir Gillet, the species retains the name which it was first given, but has a number of taxonomic synonyms. Its specific name honours Louis-Luc Godey. Within the genus Inocybe, it has been classified in a number of ways, but appears to form part of a clade (that is, a group sharing a common ancestor) with species including I. abietis, I. corydalina, I. agglutinata and I. pudica.
