Three new species of the genus Agaricus were discovered in Punjab, India between 2008-2012: A. stellatus-cuticus, A. punjabensis, and A. patialensis. A. stellatus-cuticus is characterized by a stellate splitting cap surface and abundant cheilocystidia. A. punjabensis is campestroid with an annulate stipe lacking brown scales and a pileus cuticle that does not change in KOH. A. patialensis has small, golden brown carpophores with a distinctly bulbous stipe. These new discoveries were identified through detailed examination of macroscopic and microscopic characteristics.
