In a survey of soil and herbivore dung microfungi in Mexico and Spain, several dendryphiella-like species were found. Phylogenetic analyses based on ITS and LSU sequences showed that these fungi belonged to the family Dictyosporiaceae (Pleosporales) and represent an undescribed monophyletic lineage distant from . Therefore, the genus is proposed to accommodate three new species, , and . The novel genus shares morphological features with such as differentiated conidiophores and polytretic integrated conidiogenous cells, that produce acropetal branched chains of conidia. differs in the absence of nodulose conidiophores bearing conidiogenous cells with pores surrounded by a thickened and darkened wall, typical features in the conidiogenous apparatus of . In addition, the phylogenetic and morphological analysis of several reference strains of different species, available for comparison, support the proposal of , which mainly differs from the other species of the genus by having conidia up to 7 septa and highlight that and are obscure species that require further taxonomic review.
在一项对墨西哥和西班牙土壤及食草动物粪便中的微真菌进行的调查中,发现了几种类似树状枝孢菌的物种。基于ITS和LSU序列的系统发育分析表明,这些真菌属于Dictyosporiaceae科(格孢腔菌目),代表一个未描述的单系谱系,与……亲缘关系较远。因此,提议设立一个新属来容纳三个新物种,即……、……和……。这个新属与……具有共同的形态特征,如分化的分生孢子梗和多育型整合产孢细胞,这些细胞产生向顶分枝的分生孢子链。……的不同之处在于没有具瘤状分生孢子梗,其产孢细胞带有被增厚且变黑的壁包围的孔,这是……产孢器的典型特征。此外,对几种可供比较的不同……物种参考菌株的系统发育和形态分析,支持了新属的提议,该新属与该属其他物种的主要区别在于分生孢子多达7个隔膜,并强调……和……是需要进一步分类学审查的模糊物种。
