A new species of endophytic Pezicula, named Pezicula endophytica, was discovered in roots and stems of two Dendrobium species in northern Thailand. The identification of the new species was supported by morphology and phylogenetic analysis, showing it as a distinct clade independent from other Pezicula species. Endophytica has larger macroconidia and longer conidiophores compared to its phylogenetic neighbors, marking the first report of an endophytic Pezicula species from Dendrobium in Thailand.
new species, Pezicula endophytica, was isolated from roots and stems of two Dendrobium species in northern Thailand. Evidence to support the new species is based on morphology and phylogenetic analysis of the combined ITS, LSU, and RPB2 DNA sequence dataset. Pezicula endophytica, which constituted a clade independent from other Pezicula species, has 4% distinct base pair differences in all genes. Pezicula endophytica has larger macroconidia and longer conidiophores compared with phylogenetically neighboring species. This is the first report of an endophytic Pezicula species from Dendrobium in Thailand.
