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

## TL;DR

This paper describes two new species of fungi and a new fungal record found on dead stems of Xanthoceras sorbifolium in China.

## Contribution

The study introduces two new pleosporalean fungal species and documents a new regional fungal record.

## Key findings

- Two new species, Alloleptosphaeria xanthoceratis and Lophiostoma multiforme, were identified.
- Lophiostoma montanae is reported as a new record in the region.
- Phylogenetic relationships of the three taxa were analyzed using multi-locus sequence data.

## Abstract

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 Xanthoceras sorbifolium. Morphological evidence and multi-locus sequence analyses using a combined dataset of ITS, LSU, SSU, rpb2, tef1-α, and tub2 indicate that these isolates represent two new species (Alloleptosphaeria xanthoceratis and Lophiostoma multiforme) and a new record of Lophiostoma montanae. 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.
