# Two new species of Ascomycota on bamboo leaves in Fujian, China

## TL;DR

This paper describes two new species of fungi found on bamboo leaves in China, expanding our understanding of fungal diversity associated with bamboo.

## Contribution

The study introduces two newly identified fungal species, Bifusisporella magnum and Letendraea bambusae, from bamboo leaves in Fujian, China.

## Key findings

- Two new fungal species were identified using morphological and phylogenetic analyses.
- The new species belong to the Didymosphaeriaceae and Magnaporthaceae families.
- The findings expand the known diversity and distribution of fungi associated with bamboo.

## Abstract

Bamboo is the largest member of the family Poaceae, and these fast-growing plants have many beneficial ecological effects. Both mutualistic and pathogenic fungi associate with bamboo, however, only a limited number of such fungal species have been identified, and information concerning the diversity of fungi that parasitizes bamboo leaves is sparse.

Fungi were isolated from diseased leaves of bamboo from Fujian Province, China. Nucleotide sequences of four genetic loci were used for taxonomic and phylogenetic reconstruction. In addition, the morphological characteristics of fungal structures as well as growth parameters were characterized.

We report two new fungal species, one each within the Didymosphaeriaceae and Magnaporthaceae, both diverse genera that include saprophytes, endophytes, and pathogens. Based on combined morphological and phylogenetic analyses, including the nucleotide sequences of the internal transcribed spacer (ITS), the 28S large subunit of ribosomal RNA (LSU), the 18S small subunit of nuclear ribosomal RNA gene (SSU), the large subunit of RNA polymerase I (rpb1), and the translation elongation factor 1-α gene (tef1-α), the two new species described herein have been named as Bifusisporella magnum sp. nov., and Letendraea bambusae sp. nov. Detailed descriptions and morphological features of the species are provided.

These data identify and describe new species within the Didymosphaeriaceae and Magnaporthaceae, expanding the diversity and distribution of fungi associating with bamboo.
