摘要

The present paper describes a novel clavarioid species, Lachnocladium sevyakrishnarum sp. nov., collected from Bengaluru, Karnataka, India. Basidiomata coralloid, 0.5–1.5 cm high, wiry, spine-like, cartilaginous to fibrous, whitish to cream, surface hairy to cottony due to sterile hyphae; basidiomata attached to soil. Hyphal system dimitic with clamped, thin-walled generative hyphae and thick-walled, yellowish to brown skeletal hyphae. Basidia clavate to sub-cylindrical (15–25 × 4–6 μm), with four sterigmata. Basidiospores globose to subglobose, hyaline, smooth, thin-walled, non-amyloid, 6.5–8.5 μm; Phylogenetic analysis based on nrITS sequences confirmed its placement within the genus Lachnocladium and supported its novelty as a distinct taxon. A detailed morphological description, illustrations, and ITS sequence data are provided. This represents the first report of a Lachnocladium species from urban Bengaluru, highlighting unexplored clavarioid diversity in southern India.
