Ganoderma curtisii dataset 2025

Ganoderma curtisii, a potential medicinal species due to the presence of various lucidenic
acids, was originally described from the southeastern United States. Controversy
subsequently developed as it became clear that this was not a single species but a complex.
In the present study, 39 collections from the G. curtisii complex, including 30 collections
originating from four different states of Mexico and type specimens were analyzed from a
phylogenetic, morphological, and ecological point of view. The phylogenetic relationships
within the G. curtisii complex were analyzed using sequence data from ITS, tef1, rpb1, and
rpb2 regions. A total of six clades were resolved within the G. curtisii complex, that
corresponds to G. curtisii, G. myanmarense, G. ravenelii, G. sichuanense, Ganoderma sp.
from Costa Rica, and a clade comprising several collections previously named G. curtisii
from Mexico, described here as Ganoderma mexicurtisii sp. nov. Furthermore, G.
meredithiae is confirmed as a synonym of G. curtisii.
