Abstract
There have been few studies on the taxonomy and biodiversity of the genus
Lentinus
in Thailand, which is a genus of edible mushrooms. Recently, collections from 17 sites in northern Thailand yielded 47 specimens of
Lentinus
sensu lato. Three were shown to be new species of
Lentinus
sensu stricto and
Lentinus roseus, L. concentricus
and
L. megacystidiatus
are introduced in this paper. The new species are described and illustrated with line drawings and are justified and compared with similar taxa. Furthermore, ITS sequence data do not match closely with any species presently lodged in GenBank.
