Pluteus canaliculatus (Pluteaceae: Agaricomycetes), a new species of Pluteus section Celluloderma from Turkey
Bibliographic record
Abstract
During a survey of the macrofungal diversity in the Sweetgum Forest Nature Protection Area (Burdur Province), southwestern Turkey, we discovered a new species of Pluteus. The species is described and illustrated here as Pluteus canaliculatus, based on its morphological characteristics and molecular phylogenetic analyses. The new species was found on wood in a Liquidambar orientalis forest and is characterized by a light brown-yellow to reddish brown canaliculate pileus, ochre brown lamellar edges, a shiny, silvery cream stipe, predominantly ellipsoid basidiospores, mostly narrowly fusiform to fusiform pleurocystidia, often with a moniliform to flexuose neck, and an euhymeniderm or a transitional (hymeniderm and epithelium) type of pileipellis. Phylogenetic analyses of nuclear ribosomal internal transcribed spacer ITS1-5.8S-ITS2 (ITS) region sequences reveal that Pluteus canaliculatus belongs to Pluteus sect. Celluloderma, forming a distinct lineage in the /thomsonii clade. A description and a comparison with morphologically similar and closely related species are provided, together with colour photographs and line drawings of the species.

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.
