Neotypification of <i>Muyocopron dipterocarpi</i>, a new host record on <i>Zanthoxylum</i> <i>fagara</i> (Rutaceae) and the potential for secondary metabolite production in Muyocopronaceae

Abstract

<italic>Muyocopron</italic> is a genus with a diverse lifestyle, occurring in tropical and temperate regions and can be found on various hosts and habitats. The present study confirmed a new host record of <italic>Muyocopron dipterocarpi</italic> from dead twigs of <italic>Zanthoxylum</italic> <italic>fagara</italic> in northern Thailand, based on both morphological comparisons with multigene analyses of LSU, SSU, ITS, and TEF1 sequence data. A preliminary screening test also showed that <italic>M. dipterocarpi</italic> has a potential for antimicrobial activity, observable as partial inhibition, when compared with the positive control. In addition, a neotype is designated here for <italic>Mu. dipterocarpi</italic> due to the original material no longer existing. This will facilitate subsequent taxonomic work in stabilizing the application of name, and to serve as a foundation for further applied research of this species.
