isolates were collected from moist soils near a water source in different areas of China. ITS sequences were submitted to MIST (Multiloci Identification System for ) and meets the [ITS] standard. Combined analyses of phylogenetic analyses of both phylograms (-α and ) and morphological characteristics, revealed five new species of , namely , , , and . Phylogenetic analyses showed and belong to the Polysporum clade, , while and belong to the Viride clade. Each new taxon formed a distinct clade in phylogenetic analysis and have unique sequences of -α and that meet the new species standard. The conidiation of typically appeared in white pustules in concentric rings on PDA or MEA and its conidia had one or few distinctly verrucose. Conidiophores of are short and rarely branched, phialides usually curved and irregularly disposed. The aerial mycelium of and formed strands to floccose mat, conidiation tardy and scattered in tufts, conidiophores repeatedly rebranching in dendriform structure. The phialides of lageniform are curved on PDA and its conidia are globose to obovoidal and large.
分离株采集自中国不同地区水源附近的湿润土壤。ITS序列提交至MIST(多基因座鉴定系统)并符合[ITS]标准。通过系统发育树(-α和)的系统发育分析与形态特征的联合分析,揭示了五个新的[物种名称]物种,即[物种名称1]、[物种名称2]、[物种名称3]、[物种名称4]和[物种名称5]。系统发育分析表明[物种名称1]和[物种名称2]属于多孢霉属分支,而[物种名称3]和[物种名称4]属于绿霉属分支。每个新分类单元在系统发育分析中形成一个独特的分支,并且具有符合新物种标准的独特的-α和序列。[物种名称5]的分生孢子形成通常出现在PDA或MEA上呈同心环的白色脓疱中,其分生孢子有一个或几个明显的疣状。[物种名称1]的分生孢子梗短且很少分枝,瓶梗通常弯曲且排列不规则。[物种名称2]和[物种名称3]的气生菌丝形成股线至絮状垫,分生孢子形成迟缓且成簇分散,分生孢子梗在树状结构中反复再分枝。[物种名称4]的瓶梗在PDA上呈瓶状且弯曲,其分生孢子为球形至倒卵形且较大。
