To date there is virtually no information available concerning the fungi associated with Tectona grandis (teak) (Lamiaceae) in Thailand. In this study, samples of microfungi were collected from both asymptomatic stems and dead wood, and symptomatic branches, stem and leaves of T. grandis from 27 sites in six provinces (Chiang Mai, Chiang Rai, Phayao, Phitsanulok, Phrae and Uttaradit Provinces). Morphology and combined multi-gene phylogeny (CAL, GAPDH, ITS, LSU, RPB2, SSU, TEF1 and TUB) were used to identify taxa. A total of 270 collections, representing 28 fungal species residing in 12 families, 7 orders and 21 genera, with three species of uncertain taxonomic placement were identified. Of these, one family, three genera and 14 species are new to science. The new family, Pseudocoleodictyosporaceae is introduced based on its distinct lineage in the Dothideomycetes and its unique morphology as compared to Roussoellaceae and Torulaceae. The new genera are Neooccultibambusa, Pseudocoleodictyospora and Subglobosporium. The newly described species are Diaporthe neoraonikayaporum, D. tectonendophytica, D. tectonae, D. tectonigena, Hermatomyces tectonae, H. thailandica, Manoharachariella tectonae, Neooccultibambusa chiangraiensis, Pseudocoleodictyospora sukhothaiensis, Ps. tectonae, Ps. thailandica, Rhytidhysteron tectonae, Subglobosporium tectonae and Tubeufia tectonae. Fourteen species are known published taxa including Alternaria tillandsiae, Berkleasmium talaumae, Boerlagiomyces macrospora, Ceratocladium purpureogriseum, Fusarium solani, Helicoma siamense, Lasiodiplodia theobromae, Macrovalsaria megalospora, Paradictyoarthrinium diffractum, Phaeoacremonium italicum, Sphaeropsis eucalypticola, Stachybotrys levispora, St. renispora and Thaxteriellopsis lignicola. Epitypifications or reference specimens are designated for Boerlagiomyces macrospora and Macrovalsaria megalospora. Macrovalsaria megalospora is transferred from Botryosphaeriaceae to Dothideomycetes genus, incertae sedis based on taxonomy and phylogenetic analysis, which indicate it is distinct from Botryosphaeriaceae. All fungal species represent first reports on T. grandis in Thailand. New taxa and taxa incertae sedis, as well as known taxa which are established as reference specimens or epitypes, are presented with phylogenetic tree analyses, habitat, known distribution, material examined, full descriptions, notes and figures. Information is also provided for known taxa to add to the body of knowledge and to assist those wishing to study fungi occurring on T. grandis in future.

在泰国北部的Tectona grandis（柚木）上的Microfungi

迄今为止，在泰国几乎没有关于与大花粉刺（柚木）（唇形科）有关的真菌的信息。在这项研究中，从无症状的茎和枯木以及有症状的枝，茎和叶中收集了微真菌的样品。来自六个省（清迈，清莱，帕尧，彭世洛，帕府和程逸府）的27个站点。使用形态学和组合的多基因系统发育系统（CAL，GAPDH，ITS，LSU，RPB2，SSU，TEF1和TUB）来识别分类群。共鉴定了270个收集物，分别代表12个科，7个目和21属的28个真菌物种，其中3个物种的生物分类学位置不确定。其中，一个科，三个属和14个物种是科学新事物。引入新的假单胞菌科是基于其在直链丝菌中的独特谱系以及与卢梭菌科和杜鹃花科相比独特的形态。新属是新隐球菌，假结肠菌属和Subglobosporium。新描述的物种是Diaporthe neoraonikayaporum，D. tectonendophytica，D. tectonae，D. tectonigena，Hermatomyces tectonae，H. thailandica，Manoharachariella tectonae，Neooccultibambusa chiangraiensis，Pseudocoleodictyospora sukhothaiensis，聚苯乙烯。tectonae，诗篇。thailandica，Rhytidhysteron tectonae，Subglobosporium tectonae和Tubeufia tectonae。已知有14种已出版的分类单元，包括赤tillandsiae，Berkleasmium talaumae，Boerlagiomyces macrospora，Ceratocladium purpureogriseum，茄病镰刀菌，Helicoma siamense，Lasiodiplodia theobromae，Macrovalsaria megalospora，Paradictyoarthrinium diffractum，Phaeoacremonium italicum的，枯eucalypticola，葡萄穗levispora，圣renispora和Thaxteriellopsis lignicola。表彰或参考标本被指定用于Boerlagiomyces macrospora和巨瓦尔氏菌。Macrovalsaria megalospora从转移Botryosphaeriaceae到座囊菌纲的属，地位未定基于分类和系统发育分析，这表明它是从不同Botryosphaeriaceae。所有真菌物种都代表了泰国关于巨圆线虫的首次报道。新分类群和门类地位未定，以及其建立为参考样本或epitypes已知类群，都带有系统树分析，栖息地，已知分布，材料研究，完整描述，说明和附图。还为已知的分类单元提供信息，以增加知识范围，并帮助希望研究在其上发生的真菌的人。将来的T. grandis。
