Molecular data place the hyphomycetous lichenicolous genus Sclerococcum close to Dactylospora (Eurotiomycetes) and S. parmeliae in Cladophialophora (Chaetothyriales)
Bibliographic record
Abstract
The lichenicolous anamorphic fungus Sclerococcum parmeliae was isolated in pure culture, and ITS, nuLSU and mtSSU sequences were obtained from these isolates. For comparison, sequences from S. sphaerale , the generic type, were obtained directly from freshly collected specimens. Phylogenetic analyses place S. sphaerale with species of Dactylospora and an unidentified lichen-inhabiting isolate in a strongly supported clade that is sister to a lineage comprising members of the Chaetothyriales and Pyrenulales. In contrast, S. parmeliae is inferred as a member of the Herpotrichiellaceae (Chaetothyriales) and belongs to a robustly supported clade that also includes species of Cladophialophora , Capronia semiimmersa , and Phialophora verrucosa. Within the Herpotrichiellaceae, S. parmeliae most closely resembles members of the anamorph genus Cladophialophora . Accordingly, we propose the transfer of S. parmeliae and the morphologically similar species S. cladoniae , S. hawksworthii and S. normandinae to Cladophialophora . A new lichenicolous species, Clad. megalosporae , collected twice on Megalospora in Florida and Papua New Guinea, is also described.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
