Abstract

fetched live from OpenAlex

Using field emission scanning electronmicroscopy, hyphal surfaces were examined in six lichens, Lasallia papulosa (Ach.) Llano, Xanthoria elegans (Link.) Th. Fr., Peltigera aphthosa (L.) Willd., Stereocaulon depressum (Frey) M. Lamb, Umbilicaria mammulata (Ach.) Tuck, and U. cylindrica (L.) Duby and in material of the same species associated with pathogenic or saprobic fungi. In samples infected by each of Muellerella pygmaea (Körber) D. Hawks., Marchandiomyces corallinus (Roberge) Diederich & D. Hawks., Lasiospheriopsis stereocaulicola (Lindsay) O. Eriksson & R. Sant, and a Penicillium-like fungus, some hyphae were found that differed from those of the lichen mycobiont in size, septation, surface texture, or inclination to collapse. Anomalous hyphae were uncommon in some diseased lichens, in fact no candidate pathogens were detected in S. depressum infected with Arthonia stereocaulina (Ohlert) R. Sant., although extensive mycelia of L. stereocaulicola were evident in the same lichen. The extent of visible colonization by extraneous fungi was greatest in recently killed U. mammulata.

Full frame distilled prediction

Teacher imitation

Not calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model 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.
