Inocybe romana

An Inocybe of typically Mediterranean ecology, associated with pines on sandy soils, with a fibrillose cap and caulocystidia restricted to the upper half of the stipe.

Pileipellis composed of hyphae arranged more or less parallelly, 4-10 µm wide, with yellowish-brown intracellular pigment, septate with clamped septa.

Caulocystidia present only on the upper stipe, cylindrical, sinuous, some subcapitate and thin-walled.

Cheilocystidia and pleurocystidia clavate to utriform, with rounded apices, 40-70 µm long and 11-20 µm wide, thin-walled, notably characterized by a halo-like exudate on their surface, more prominent at the apex.

Basidia clavate, 20-30 µm long and 6-9 µm wide, without basal clamps, 4-spored.

Spores ellipsoidal to subamygdaliform, smooth- and thick-walled, pale yellowish-brown under the microscope, with an eccentric apiculus at one end, containing oil droplets, dextrinoid in Melzer's reagent.
