Additions to Pleosporalean Taxa Associated with Xanthoceras sorbifolium from Jilin and Hebei, China

Pleosporalean fungi play significant roles as plant pathogens, saprobes, and endophytes in a wide variety of economically important plant hosts. During an investigation of saprobic fungi from Jilin and Hebei, China, five pleosporalean isolates were obtained from the dead stems of <i>Xanthoceras sorbifolium</i>. Morphological evidence and multi-locus sequence analyses using a combined dataset of ITS, LSU, SSU, <i>rpb</i>2, <i>tef</i>1-α, and <i>tub</i>2 indicate that these isolates represent two new species (<i>Alloleptosphaeria xanthoceratis</i> and <i>Lophiostoma multiforme</i>) and a new record of <i>Lophiostoma montanae</i>. Full morphological descriptions and illustrations are provided herein, and phylogenetic relationships of three pleosporalean taxa are also discussed. Detailed morphological descriptions and illustrations are presented, along with phylogenetic affiliations of three pleosporalean taxa.
