New species of <i>Trichoderma</i> from Asia
Bibliographic record
Abstract
Seven new species of Trichoderma, isolated from soil or tree bark from Siberia, Nepal, northern India, Taiwan, Thailand, Cambodia, and Malaysia, are described based on morphological and physiological characters, and from their phylogenetic position inferred from parsimony analyses of nucleotide sequences of the internal transcribed spacer (ITS) regions of the rDNA cluster (ITS1 and 2) and partial sequences of translation elongation factor 1-alpha (tef1α). Trichoderma sinensis sp. nov. and Trichoderma effusum sp. nov. are additions to Trichoderma section Longibrachiatum. Trichoderma helicum sp. nov., Trichoderma rossicum sp. nov., Trichoderma velutinum sp. nov., and Trichoderma cerinum sp. nov. are additions to section Pachybasium. Trichoderma erinaceum sp. nov. is described in section Trichoderma. The contribution of sequence data in resolving species in Trichoderma is demonstrated by Trichoderma helicum, which is morphologically indistinguishable from Trichoderma tomentosum Bissett, even though the two species are not phylogenetically closely related.Key words: Hypocrea, systematics, taxonomy, phylogeny.
Fetched live from OpenAlex and de-inverted. Abstracts are not stored in this database: the inverted indexes are 8.6 GB of the frame’s 9.3 GB of text, and the host has 13 GB free.

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.
