木霉菌株是从我国不同地区水源地附近的潮湿土壤中采集的。ITS序列提交给MIST（木霉多位点鉴定系统），符合木霉[ITS 76]标准。结合形态特征和系统发育分析，初步鉴定出5个木霉菌新种，分别为海拉木霉菌Trichodermahailarense、巨束木霉菌T.macrofasciculatum、诺地木霉菌T.nordicum、香格里拉木霉菌T.shangrilaense和瓦地木霉菌T. vadicola。系统发育分析表明，大束毛癣菌和香格里拉毛癣菌属于多孢菌分支，海拉尔毛癣菌属于海拉尔毛癣菌分支，而诺地毛癣菌和瓦地毛癣菌属于绿色分支。每个新分类群在系统发育分析中形成了一个独特的分支，并且具有符合木霉新种标准的独特tef 1-α和rpb 2序列。大束孢木霉分生孢子在PDA或MEA上呈同心圆状的白色脓疱，分生孢子有一个或少数明显的疣状突起。香格里拉木霉分生孢子梗短，很少分枝，瓶梗通常弯曲，排列不规则。海拉尔赤霉病菌和瓦地赤霉病菌气生菌丝呈束状至絮状，分生孢子迟成簇散生，分生孢子梗反复再分枝形成树状结构。壶状裸木霉的瓶梗在PDA上弯曲，分生孢子球形至倒卵球形，体积较大。
Trichoderma 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 Trichoderma) and meets the Trichoderma [ITS76] standard. Combined analyses of phylogenetic analyses of both phylograms (tef1-α and rpb2) and morphological characteristics, revealed five new species of Trichoderma, namely Trichodermahailarense, T.macrofasciculatum, T.nordicum, T.shangrilaense and T.vadicola. Phylogenetic analyses showed T.macrofasciculatum and T.shangrilaense belong to the Polysporum clade, T.hailarense, while T.nordicum and T.vadicola belong to the Viride clade. Each new taxon formed a distinct clade in phylogenetic analysis and have unique sequences of tef1-α and rpb2 that meet the Trichoderma new species standard. The conidiation of T.macrofasciculatum typically appeared in white pustules in concentric rings on PDA or MEA and its conidia had one or few distinctly verrucose. Conidiophores of T.shangrilaense are short and rarely branched, phialides usually curved and irregularly disposed. The aerial mycelium of T.hailarense and T.vadicola formed strands to floccose mat, conidiation tardy and scattered in tufts, conidiophores repeatedly rebranching in dendriform structure. The phialides of T.nordicum lageniform are curved on PDA and its conidia are globose to obovoidal and large.
