The latter belongs to the section Arvenses which includes other potentially cultivatable species. Despite the high Agaricus species richness already reported in Thailand only A. subrufescens and A. flocculosipes of section Arvenses have been found. In this section, we introduce Agaricus subtilipes, a new species from northern Thailand. Bayesian and maximum likelihood phylogenetic analyses of ITS ribosomal DNA showed that this new species is sister to A. flocculosipes in a clade containing other tropical members of the section. A comparison of Agaricus subtilipes with tropical species of section Arvenses from the literature led us to revisit the species A. bambusae. Unexpectedly, A. bambusae var. bambusae which was described from Africa was shown to be a synonym of Agaricus subrufescens based on molecular data. In contrast, A. bambusae var. australis which was described from New Zealand was not closely related to A. subrufescens, but was a sister species to A. subantarcticus, also described from this country; this variety is therefore raised to species rank and renamed as A. horakianus nom. nov. In experimental cultivation, a wild isolate of A. subtilipes fructified on the standard substrate for the cultivation of A. bisporus with conditions used for A. subrufescens cultivation (fruiting temperature 25°C). This first fruiting test showed that A. subtilipes can be domesticated, however further investigations are required to optimize conditions industrial yields.} }
