Pileus 0.4-0.9 cm in diameter; at first ovoid, then conic to campanulate, membranous; whitish grey to cream grey, smooth, glabrous, sulcate striate almost to the disc, margin regular. Lamellae adnexed, moderately crowded, whitish to cream, which turns dark brown, non-deliquescent, with lamellulae. Stipe 0.8-1.2 cm, cylindric, slender, hollow, equal, white, almost translucent, arising from white, mycelial threads. Context thin. Basidiospores 6.8-7.8 x 3.7-4.2 µm, ellipsoid, broadly ovate, with a thick wall, truncated by an apical germ-pore, dark brown, smooth. Basidia 22-27 x 6-9 µm, clavate with 4-sterigmata, hyaline. Pleurocystidia absent. Clamp connections absent.
Specimens examined
India, Maharashtra, Kolhapur, Ajara, Kasar Kandgaon, Ajara-Chandgad road (16°04ʹ08ʺN-74°12ʹ38ʺE), on dead wood log, in deep forest, in cluster, 22.08.2022, Bornak, S. I. (Y22V8C4).
Remarks
Coprinellus disseminatus is tiny, non-deliquescent, delicate, coprinoid mushrooms that grow sporadically on decaying wood and roots, rotting stumps, and dead wood logs. Fruit bodies frequently form in very large groups. The pileus is initially sub-globose to globose or ovoid, then hemispherical or obtusely conical to convex are creamy to nearly white at first, becoming darker as they get older; most of the gill margins lack cheilocystidia, while pileocystidia are spherical, lageniform, and have a cylindrical neck. (Hussain, et al., 2018). It has been reported from Karnataka, Kerala, Punjab, Sikkim, Uttar Pradesh, Jammu and Kashmir and West Bengal. Sathe and Rahalkar (1975) and Sathe and Deshpande (1982) reported this species from Pune, Maharashtra as Coprinus disseminates. This is a nomenclatural correction as well as a new report from the study area.
