Observation of spore germination in Physarum globuliferum
Bibliographic record
Abstract
We described in detail the spore germination events in Physarum globuliferum. Observations were made using depression slides under a computer-supported video microscope. When a spore germinated, one protoplast, one myxamoeba or one swarm cell emerged; not more than one of these was observed. Under most conditions, the release of the spore protoplast was accomplished by the splitting of the spore wall into what appeared to be a V-shaped opening. Sometimes, the spores germinated through a minute pore dissolved in the spore wall and a myxamoeba or a swarm cell emerges. Under unfavorable conditions, myxamoeba may round up to form microcysts. Swarm cells are peanut-like, with one anteriorly attached flagellum. The pseudopodium of the myxamoeba is a typical lobopodium containing endoplasm only. Key words: Myxomycete, protoplast, swarm cell, myxamoeba, microcyst.
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.
