Abstract

Two new Kirschsteiniothelia species are proposed in this study; both were collected on decaying wood from Chiang Mai and Chiang Rai provinces in northern Thailand. The taxa were isolated and the morphological characters are described and illustrated. ITS, LSU and SSU combined sequence analysis showed taxa of Kirschsteiniothelia separating into three lineages: (i) K. elaterascus grouped within Morosphaeriaceae (Pleosporales); (ii) K. maritima clustered with Mytilinidion spp. as a sister group in the Mytilinidiaceae clade; and (iii) the two new Kirschsteiniothelia species, which produce Dendryphiopsis anamorphs in culture, clustered with K. aethiops (the generic type) and the anamorph D. atra. The new family Kirschsteiniotheliaceae is introduced to accommodate taxa grouping with K. aethiops. K. elaterascus is transferred to Morosphaeria (Morosphaeriaceae) and a new genus Halokirschteiniothelia is introduced to accommodate K. maritima (Mytilinidiaceae).

摘要

本研究提出了两个新的 Kirschsteiniothelia 种；均采自泰国北部清迈和清莱省的腐朽木材。对这些类群进行了分离，并对其形态特征进行了描述和说明。ITS、LSU 和 SSU 联合序列分析表明，Kirschsteiniothelia 类群分为三个谱系：(i) K. elaterascus 属于 Morosphaeriaceae（Pleosporales）；(ii) K. maritima 与 Mytilinidion spp.聚为姐妹群，位于 Mytilinidiaceae 分支中；(iii) 两个新的 Kirschsteiniothelia 种在培养中产生 Dendryphiopsis 无性型，与 K. aethiops（属的模式种）和无性型 D. atra 聚在一起。新的 Kirschsteiniotheliaceae 科被引入以容纳与 K. aethiops 聚为一类的类群。K. elaterascus 被转移到 Morosphaeria（Morosphaeriaceae），一个新的属 Halokirschsteiniothelia 被引入以容纳 K. maritima（Mytilinidiaceae）。
