Using morphological characters, cultural characters, large subunit and internal transcribed spacer rDNA (ITS) sequences, and provisions of the International Code of Botanical Nomenclature, this paper attempts to resolve the taxonomic and nomenclatural confusion surrounding three species of cladosporium-like hyphomycetes. The type specimen of Hormodendrum resinae, the basis for the use of the epithet resinae for the creosote fungus {either as Hormoconis resinae or Cladosporium resinae) represents the mononematous synanamorph of the synnematous, resinicolous fungus Sorocybe resinae. The phylogenetic relationships of the creosote fungus, which is the anamorph of Amorphotheca resinae, are with the family Myxotrichaceae, whereas S. resinae is related to Capronia (Chaetothyriales, Herpotrichiellaceae). Our data support the segregation of Pycnostysanus azaleae, the cause of bud blast of rhododendrons, in the recently described anamorph genus Seifertia, distinct from Sorocybe; this species is related to the Dothideomycetes but its exact phylogenetic placement is uncertain. To formally stabilize the name of the anamorph of the creosote fungus, conservation of Hormodendrum resinae with a new holotype should be considered. The paraphyly of the family Myxotrichaceae with the Amorphothecaceae suggested by ITS sequences should be confirmed with additional genes.

三种类似枝孢菌的丝状菌、Sorocybe resinae、Seifertia azaleae 和 Amorphotheca resinae 的 Hormoconis anamorph 的分类学、命名法和系统发育。

本文利用形态特征、文化特征、大亚基和内部转录间隔区 rDNA (ITS) 序列以及国际植物命名法典的规定,试图解决围绕三个类枝孢子菌的分类和命名混乱。Hormodendrum resinae 的模式标本,作为杂酚油真菌(作为 Hormoconis resinae 或 Cladosporium resinae)使用加词树脂的基础,代表了同线、树脂色真菌 Sorocybe resinae 的单线同形异形体。作为 Amorphotheca resinae 的无型态的杂酚油真菌的系统发育关系与 Myxotrichaceae 家族有关,而 S. resinae 与 Capronia (Chaetothyriales, Herpotrichiellaceae) 相关。我们的数据支持杜鹃花芽孢的原因 Pycnostysanus azaleae 的分离,在最近描述的 Seifertia 属中,与 Sorocybe 不同;该物种与 Dothideomycetes 相关,但其确切的系统发育位置尚不确定。为了正式稳定杂酚油真菌无性形体的名称,应考虑用新的正模保护 Hormodendrum resinae。ITS 序列建议的粘菌科与 Amorphothecaceae 的副系应该用额外的基因来确认。应该考虑用新的正模保护树脂草。ITS 序列建议的粘菌科与 Amorphothecaceae 的副系应该用额外的基因来确认。应该考虑用新的正模保护树脂草。ITS 序列建议的粘菌科与 Amorphothecaceae 的副系应该用额外的基因来确认。
