Remarks

Agaricus trisulphuratus, is recognizable by tiny basidiomes with reddish-orange pileus and stipe surfaces that have a well-developed, global veil that is concolorous on both the pileal and stipe surfaces and indistinct, floccose annulus at the apex of the stipe. Previously this species has been reported from Karnataka, Kerala, Punjab, Tamil Nadu, Uttar Pradesh and West Bengal. From Maharashtra it has been reported from Pune, Mulshi and Ratnagiri (Senthilarasu and Kumaresan, 2016). This is a new report from the study area.
