Entoloma sequestratum, a new species from the rainforests of northern Thailand, and a worldwide key to the sequestrate taxa of Entoloma (Entolomataceae).

Based on our study of the morphology and genetics of sporocarps collected in the mountains of northern Thailand, we herein describe Entoloma sequestratum as a new sequestrate member of the Entolomotaceae. This serves as the first report of a sequestrate member of the genus from Thailand. In addition, we provide a worldwide key to all of the described sequestrate members of the genus.
