Abstract

Two dark-spored agaric species from Asia are placed in the genus Anamika (Agaricales or euagarics clade). This result is supported by ITS and nLSU-rDNA sequences with strong measures of branch support, in addition to several morphological and ecological similarities. An inclusive ITS study was performed using a mixed model Bayesian analysis that suggests the derived status of Anamika within Hebeloma, thereby rendering Hebeloma a paraphyletic genus. However, the monophyly of Hebeloma cannot be rejected outright given ITS and nLSU-rDNA data. Thus, we propose two new Asian species in Anamika: A. angustilamellata sp. nov. from dipterocarp and fagaceous forests of southwestern China and northern Thailand; and A. lactariolens comb. nov., a Japanese species originally described in the genus Alnicola. A complete description of A. angustilamellata, including illustrations, is provided.
