This agaric is characterized by the dense pyramidal scales over the disc of the pileus and the appressed scales toward the margin, and a similar decoration of scales on the stipe; the odor is spermatic. Microscopically the basidiospores are smooth and there are abundant, moderately thick-walled hyemnial cystidia. This Inocybe is associated with Quercus costaricensis at around 3000 m elevation in the Cordillera Talamanca.
