Notes.

Wanasinghe et al. (2016) regarded Munkovalsaria as a synonym of Montagnula and established Montagnula donacina (= Munkovalsaria donacina ). So far, Montagnula donacina stands as the most extensively distributed species within the genus. Despite its global presence, there is a scarcity of molecular data available for Montagnula donacina . A preliminary analysis revealed only 20 sequence data entries when searching for " Montagnula donacina " in the NCBI database, originating from only seven strains: HFG07004, HKAS 124552, HVVV01, KUMCC 21-0579, KUMCC 21-0631, KUMCC 21-0653, and UESTCC:23.0030. Our phylogenetic analysis demonstrated a close relationship between two strains designated as Montagnula donacina (HVVV01 and HFG07004) and the type strain of Montagnula chromolaenicola (MFLUCC 17-1469). Additionally, we observed that the strains of Montagnula thailandica formed a monophyletic group alongside the remaining Montagnula donacina strains (HKAS 124552, KUMCC 21-0579, KUMCC 21-0631, KUMCC 21-0653, and UESTCC:23.0030). Furthermore, two newly generated sequences, KUNCC 23-14428 and KUNCC 23-14429, were also clustered with the strains of Montagnula donacina . We hereby introduce these two strains as belonging to Montagnula donacina and provide rpb 2 sequence data for this species for the first time.
