Four New Phaeocollybia Fungus Species from Yunnan Province

2026 research by San-Zhao Chen describes and illustrates four newly discovered species of the Phaeocollybia fungus genus from southwestern China. The dataset includes morphological descriptions, color photos, microscopic drawings, and phylogenetic analyses based on ITS and RPB2 DNA sequences. This is a small, specialized dataset of 96.6 KB containing FASTA and TREE file formats.

Use Cases

• Phylogenetic tree construction using the provided TRE and TREEFILE data to place new species within subgenus Phaeocollybia.
• Morphological comparison of species using the described features and line drawings of microscopic structures.
• DNA sequence analysis for species identification using the included ITS and RPB2 gene sequences in FASTA format.
• Validation of fungal species descriptions by cross-referencing color photos of fresh basidiomata with taxonomic keys.

Strengths

• Includes multilocus phylogenetic data from two genetic markers (ITS and RPB2).
• Provides multimodal evidence: DNA sequences, color photographs, and detailed microscopic illustrations.
• Describes four previously undocumented species with clear taxonomic comparisons.

Limitations

• Extremely limited scope of only four species from a single genus and geographic region (Yunnan Province).
• Sample size is inherently small, focused on novel discoveries rather than a broad survey.
• No raw columnar data or sample records are provided, only analysis outputs and descriptive documents.
