摘要

从泰国北部两个石斛属植物的根和茎中分离得到一个新物种——内生Pezicula。支持新物种的证据是基于ITS、LSU和RPB2 DNA序列数据集的形态学和系统发育分析。内生辣椒是一个独立于其他辣椒属物种的分支，在所有基因中都有4%的不同碱基对差异。与系统发育上相邻的物种相比，内生Pezicula具有更大的大孢子和更长的分生孢子。这是泰国石斛属植物内生Pezicula的首次报道。

Pezicula endophytica sp. nov., endophytic in Dendrobium in Thailand

A 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.
