Ganoderma curtisii dataset 2025

Ganoderma curtisii, a potential medicinal species due to the presence of various lucidenicacids, was originally described from the southeastern United States. Controversysubsequently 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 collectionsoriginating from four different states of Mexico and type specimens were analyzed from aphylogenetic, morphological, and ecological point of view. The phylogenetic relationshipswithin the G. curtisii complex were analyzed using sequence data from ITS, tef1, rpb1, andrpb2 regions. A total of six clades were resolved within the G. curtisii complex, thatcorresponds to G. curtisii, G. myanmarense, G. ravenelii, G. sichuanense, Ganoderma sp.from Costa Rica, and a clade comprising several collections previously named G. curtisiifrom Mexico, described here as Ganoderma mexicurtisii sp. nov. Furthermore, G.meredithiae is confirmed as a synonym of G. curtisii.
