The genus Catenularia (Chaetosphaeriaceae) was reviewed, and its relationships with morphologically similar fungi were evaluated using molecular and morphological data. Eleven species are accepted, four of which have been verified with molecular DNA data. The correct epithet ‘cupulifera’ is proposed for the type species C. cupuliferacomb. nov. Four other combinations are proposed, namely C. catenulatacomb. nov., C. elsikiicomb. nov., C. minorcomb. nov. and C. novae-zelandiaecomb. nov.Catenularia is an uncommon fungus inhabiting mainly decaying bark, wood and bamboo culms of various hosts and shows a widespread geographical distribution. It is circumscribed for fungi with mononematous, macronematous, simple conidiophores with terminal monophialides, usually accompanied with capitate hyphae. The conidia are aseptate, brown, cuneiform to rounded-obconic with an angular outline, adhering in chains. The diagnostic values of taxonomic characteristics of capitate hyphae and conidia (i.e. colour, shape in transverse section, setulae and formation) at the generic level were evaluated. An account of morphology, taxonomy and phylogeny of species accepted in Catenularia is provided. Based on ribosomal DNA sequences, Chalarodes obpyramidatasp. nov., characterised by catenate, angular, hyaline conidia with apical setulae, is revealed as closely related to Catenularia. The new genus Fuscocatenulagen. nov. is proposed for catenularia-like fungi having pigmented conidia with protracted maturation and round outline, with two species accepted, F. submersacomb. nov. and F. variegatacomb. nov. A new species Nawawia antennatasp. nov. is introduced and Nawawia is compared with morphologically similar taxa.

Catenularia 和具有链状分生孢子的类似真菌的系统发育和分类

审查了链状菌属（Chaetosphaeriaceae），并使用分子和形态数据评估了其与形态相似真菌的关系。接受了 11 种物种，其中四种已通过分子 DNA 数据验证。正确的加词 'cupulifera' 被提议用于模式种 C. cupuliferacomb。十一月 提出了其他四种组合，即 C. catenulatacomb。十一月，C. elsikiicomb。十一月，C.小梳子。十一月 和 C. novae-zelandiaecomb。nov.Catenularia 是一种罕见的真菌，主要栖息在各种宿主的腐烂树皮、木材和竹秆上，具有广泛的地理分布。它被限定为具有单线、大线、单分生孢子梗的真菌，带有末端单孢菌，通常伴有头状菌丝。分生孢子是无分隔的，棕色的，楔形到倒圆倒圆锥形，有棱有角的轮廓，依附于链状。评价了头状菌丝和分生孢子的分类特征（即颜色、横切面形状、小刚毛和形态）在属水平上的诊断价值。提供了在 Catenularia 中接受的物种的形态学、分类学和系统发育的说明。基于核糖体 DNA 序列，Chalarodes obpyramidatasp。11 月，其特征是链状的、有角的、透明的分生孢子具有顶端小刚毛，被揭示为与 Catenularia 密切相关。新属 Fuscocatenulagen。十一月 建议用于具有色素分生孢子、成熟时间长和圆形轮廓的类链状真菌，接受两个物种 F. submersacomb。十一月 和 F. variegatacomb。十一月 一个新物种 Nawawia 触角。十一月
