Penicillium mallochii and P. guanacastense, two new species isolated from Costa Rican caterpillars
Bibliographic record
Abstract
Twenty-five strains of monoverticillate Penicillium species were isolated from dissected guts and fecal pellets of leaf-eating caterpillars reared in the Área de Conservación Guanacaste, Costa Rica, or from washed leaves of their food plants. Phylogenetic analyses of β-tubulin, nuclear ribosomal internal transcribed spacer (ITS), cytochrome c oxidase subunit 1, translation elongation factor 1- α and calmodulin gene sequences revealed two phylogenetically distinct, undescribed species closely related to P. sclerotiorum . Penicillium mallochii was isolated from Rothschildia lebeau and Citheronia lobesis ( Saturniidae ) and their food plant Spondias mombin ( Anacardiaceae ) and P. guanacastense from Eutelia sp. ( Noctuidae ). Both fungi produce greenish conidial masses and orange pigments in agar culture, have smooth-walled, monoverticillate conidiophores with moderately vesiculate apices, and globose to subglobose conidia. The species morphologically resemble P. sclerotiorum but differ subtly in vesicle width and conidial shape.
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.
