Lepiota (Agaricales) in northern Thailand-2 Lepiota section Lepiota

In this report, we investigate the presence of Lepiota species in section Lepiota in Northern Thailand (Chiang Mai and Chiang Rai). Five Lepiota species are characterised by distinct fusiform-amygdaliform spores. Of these, three species, namely L. eurysperma, L. microcarpa, and L. pongduadensis, are proposed as new species; L. metulispora is a new record for Thailand. Macro- and microscopic descriptions, illustrations, and a key to the species are provided. In addition, the identity of these Lepiota species is also clarified based on molecular data.
