Graminicolous Downy Mildew Fungarium Specimens with 429 Ortholog Sequences

57 fungarium specimens, including 17 types, were sequenced for 429 orthologs to construct a phylogeny from 62 loci. The data was generated by GLEN GROBEN using an oomycete-specific target enrichment protocol and last updated on May 11, 2026. It supports taxonomic revision and reveals that nearly half of the examined specimens were misidentified.

Use Cases

• Validating species concepts and type materials based on molecular phylogeny.
• Developing diagnostic tools for high-risk plant pathogens like Peronosclerospora philippinensis and P. sacchari.
• Identifying potential undescribed species from the 12 distinct lineages revealed.
• Assessing historical specimen misidentification rates using molecular data.

Strengths

• Includes 17 type specimens, anchoring molecular data to nomenclatural types.
• Sequences 429 orthologs from 57 fungarium specimens.
• Uses a specific protocol for degraded DNA from historical specimens.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• Data is derived from historical fungarium specimens, which may have degraded DNA embedded in host tissue.
