Abstract

Tricholosporum tamilnaduense sp. nov. is reported here from the Eastern Ghats of Tamil Nadu, India. Tricholosporum tamilnaduense is well supported by the morphological characteristics by having broadly umbonate pale orange pileus 3.5–5 cm broad with a shallow central depression, violet-white margin, pale lilac emarginate lamellae and a short stipe 2.3–3.7 cm long, with an apex pruina; cruciate, hyaline, inamyloid basidiospores measuring 4–6 × 3–4 µm, clavate basidia 17–23 µm long and the cystidia bulbous or ampullaceous, measuring 16–35 µm long with a fusoid or mucronate apex. Further, the phylogenetic studies validate the morphological evidence for T. tamilnaduense sp. nov. through the nrDNA ITS sequence by forming a separate branch among the other Tricholosporum species. A description, illustrations, and phylogenetic analysis results of the new species are provided.
