Notes

Mendogia calami was recently introduced from leaves of Calamus sp. in the Philippines ( Jiang et al. 2020). However, there are no discernible differences between M. philippinensis and M. calami , neither in phenotype nor in substrate ecology. Jiang et al. (2020) did not discuss M. philippinensis when establishing M. calami and the difference implied in the table and key (ascostroma size, number of longitudinal septa) are either due to age (ascostroma size) or they are non-existent (the ascospores of M. calami have mostly one, rarely two longitudinal septa in the photographs and the protologue of M. philippinensis also indicates mostly one longitudinal septum) ( Sydow and Sydow 1917). This synonymy needs further testing with molecular data as previous studies on palms have shown that the taxa on different palm species differ ( Konta et al. 2016, Konta et al. 2017) as they may have derived from endophytes.
