Remarks

Chlorophyllum molybdites is assigned to sect. Chlorophyllum, which is characterized by olive to greenish-white basidiospores with a truncate apex, broadly clavate to sphaero-pedunculate cheilocystidia and a palisade-like pileipellis of hyphae with terminal elements clavate to sub-fusiform (Ge, et al., 2018). The species has been reported from Karnataka, Kerala, Tamil Nadu and Uttar Pradesh (Senthilarasu and Kumaresan, 2016), Pune, Maharashtra (Sathe and Rahalkar, 1976; Sathe and Deshpande, 1980,1982), Kolhapur, Maharashtra (Patil and Thite, 1978); Amravati, Maharashtra (Hedawoo, 2010).
