Etymology:—the specific epithet “ cervenianensis ” derives from the old latin name of Cervignano del Friuli, a city in Friuli Venezia Giulia Region where the holotype was collected.

Diagnosis:— Inocybe cervenianensis is characterised by its medium-sized basidiomes, with brown to ochraceous pileus, covered with whitish velipellis, stipe entirely pruinose, with more or less marginate bulb, brownish with pinkish tinges on the middle but constantly whitish in the upper part. Microscopically, it is characterised by amygdaliform spores, pleurocystidia and cheilocystidia ranging from slenderly fusiform, sublageniform to ventricose-fusiform and caulocystidia mixed with cauloparacystidia descending to the base of the stipe.
