Overview

Phylogenetic analysis demonstrates that Xylomelasma is congeneric with Ceratostomella and resolves two cryptic species, highlighting the necessity of multi-gene barcoding in fungal taxonomy.

Key Points

  • Assess the phylogenetic relationships between Ceratostomella and Xylomelasma to clarify generic boundaries and resolve species diversity within the Sordariomycetes.
  • Conducted phylogenetic analyses utilizing three- and five-gene markers, including ITS, rpb2, and tef1-α, alongside maximum likelihood analyses.
  • Integrated micromorphological assessments, global metabarcoding data, and whole-genome sequencing of three ex-type strains.
  • Demonstrated that Xylomelasma is congeneric with Ceratostomella, proposing two new combinations (C. sordida and C. novae-zelandiae) and describing two cryptic species (C. crypta and C. melanospora).
  • Identified the ascogenous system as a diagnostic generic marker and retained Ceratostomella as incertae sedis due to lack of support for inclusion in Barbatosphaeriaceae.
  • Established that Ceratostomella comprises eight recognized species distributed worldwide across soil, decaying wood, air, dust, and plant tissues.
