Remarks
Description of Clavulinopsis amoena matches with description given by Furtado, et al. (2016). The species characterized by the presence of globose to sub-globose basidiospores, a short, white villous or strigose stipe, intensely greenish yellow guttules at maturity, and tiny orange granules in the sub-hymenial hyphae that turn green when exposed to iodine are characteristics that make C. amoena clearly identifiable.The similar species with C. amoena is C. spiralis and also looks like a bright yellow form of C. fusiformis. C. fusiformis is distinct due to its mature basidiomata that range from golden to brownish yellow and its basidiospores that are broadly ellipsoid to pip-shaped, with a bigger hilar appendage and C. spiralis differs from C. amoena only by its smaller basidiospores (Furtado, et al., 2016). This species had wide distribution. In India, the species has been reported from Dalhausi, Himachal Pradesh, but not from Maharashtra (Verma and Pandro, 2018). This is the first report from Maharashtra state.
