Limacellopsis Zhu L. Yang, Q. Cai & Y.Y. Cui, in Yang et al. Biosystematics and Ecology Series 34: 366 (2018)
Etymology: “Limacellopsis” similar to Limacella.
Diagnosis: Pileus slightly viscid. Stipe dry or only slightly viscid, glabrous, or fribrilose under a large dry persistent membranous annulus. Pileipellis an ixotrichoderm composed of inflated cells in short chains, and upwards attenuate terminal cells.
Basidiomata medium sized to large. Pileus convex to plano-convex, smooth, occasionally finely cracked, slightly viscid; margin non-striate, non-appendiculate. Lamellae free, crowded, white to cream coloured; lamellulae attenuate to round attenuate. Stipe sub-cylindric, glabrous or fribrillose under the annulus; base somewhat enlarged. Annulus present, subapical to superior, skirt-shaped, membranous, persistent. Lamellar trama bilateral. Subhymenium composed of subglobose to ellipsoid or irregularly shaped cells. Basidia clavate. Basidiospores globose, sub-globose to ellipsoid, inamyloid, non-dextrinoid, colourless, hyaline, thin-walled, smooth to asperulate; apiculus relatively large. Pleurocystidia and cheilocystidia absent. Pileipellis an ixotrichoderm composed of inflated cells in shrot chains, with upwards attenuate terminal cells. Stipe trama composed of longitudinally arranged filamentous hyphae, mixed with long ellipsoid cells and clavate to subclavate terminal cells. All hyphae with clamped septa.
