Sarocladium species are common endophytes of tropical forage grasses and may offer benefits to host plants against biotic and abiotic stresses. We investigated a collection of 88 Sarocladium isolates previously obtained as endophytes from Panicum maximum, Pennisetum purpureum, Cynodon nlemfuensis, and Brachiaria spp. in Brazil. Multilocus phylogenetic analyses and morphological characterization were used for species delimitation. Sixty-eight isolates were identified as S. spinificis, and five as S. terricola; S. bactrocephalum, S. kiliense, S. spirale, and S. strictum were represented by one to three isolates. A well-supported clade containing eight endophytic isolates occupied a sister position to the clade containing S. bactrocephalum, S. mali, and S. strictum, and is described as a new taxon, Sarocladium graminicola. This work provides new insights on the distribution and diversity of endophytic Sarocladium species in the tropics.

Sarocladium graminicola，一种来自热带草的新内生物种

沙棘属物种是热带牧草的常见内生菌，可能为寄主植物抵御生物和非生物胁迫带来好处。我们调查了88的集合Sarocladium从内生菌菌株以前获得黍，象草，狗牙根nlemfuensis和臂形草属。在巴西。多基因座系统发育分析和形态学表征用于物种界定。分离到的有68株为棘孢链霉菌，有5株为沙门氏菌。杆菌，链球菌，螺旋杆菌和严格链球菌以一到三个分离株代表。包含八个内生分离株甲良好支持进化枝占据的妹妹位置到含有进化枝S. bactrocephalum，S.马里，和S. strictum，并且被描述为一个新的分类群，Sarocladium蛛。这项工作为热带地区内生Sarocladium物种的分布和多样性提供了新见解。
