Abstract
Fungal pathogens frequently form appressoria, specialized hyphal swellings on the surfaces of hosts. Production of appressoria by two entomophthoralean species that infect lepidopteran larvae, Entomophaga maimaiga Humber, Shimazu & Soper and Furia gastropachae (Raciborski) Filotas, Hajek & Humber, was investigated in vitro 68 h after conidial discharge. Entomophaga maimaiga appressoria were elongate, irregularly swollen structures located adjacent to the conidium or at the ends of short germ tubes. The highest percentages of appressoria were formed on hard surfaces such as polystyrene (21.5 ± 4.6%) and mylar (22.2 ± 4.3%). Nutrients or chemical stimuli were not required for appressorial formation but could stimulate growth as germ tubes. The contribution of surface hydrophobicity to appressorium formation was questionable; while appressoria were formed on hydrophobic surfaces, they were also formed to a lesser extent on glass, which is hydrophilic. When conidia of F. gastropachae were exposed to similar substrates and conditions, appressoria were never made, supporting the hypothesis that stimuli for appressorium formation can be species specific.Key words: appressorium, entomopathogenic fungi, infection process, Entomophthorales.

Full frame distilled prediction
Teacher imitationNot 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.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from it
