湖南省[具体生物]物种的特征描述及两个新物种的记述。（你提供的原文中“on in”之间似乎缺失关键信息，我根据推测补充了“[具体生物]”以使译文更完整合理，你可根据实际情况修改。）

Tea-oil tree ( Abel.) is an important edible oil woody plant with a planting area over 3,800,000 hectares in southern China. Species of inhabit a wide range of plant hosts as plant pathogens, endophytes and saprobes. At present, relatively little is known about the taxonomy and genetic diversity of on . Here, we conducted an extensive field survey in Hunan Province in China to identify and characterise species associated with tea-oil leaf spots. As a result, eleven isolates of were obtained from symptomatic leaves. These isolates were studied by applying a polyphasic approach including morphological and phylogenetic analyses of partial ITS, , , and gene regions. Two new species ( and ) were proposed and described herein, and was revealed to be new host records of and . This study indicated there is a potential of more undiscovered species from in China.

油茶树（阿贝尔.）是一种重要的食用油木本植物，在中国南方种植面积超过380万公顷。[该属物种]作为植物病原体、内生菌和腐生菌栖息于广泛的植物宿主中。目前，关于[该属物种]在油茶树上的分类学和遗传多样性了解相对较少。在此，我们在中国湖南省进行了广泛的实地调查，以鉴定和表征与油茶叶斑相关的[该属物种]。结果，从有症状的油茶叶片中获得了11个[该属物种]分离株。通过应用多相方法对部分ITS、[其他基因名称未完整给出]、[其他基因名称未完整给出]、[其他基因名称未完整给出]和[其他基因名称未完整给出]基因区域进行形态学和系统发育分析，对这些分离株进行了研究。本文提出并描述了两个新的[该属物种]（[物种名称未完整给出]和[物种名称未完整给出]），并且[物种名称未完整给出]被揭示为[该属物种]和[该属物种]的新宿主记录。这项研究表明中国油茶树上可能存在更多未被发现的[该属物种]。
