<b><i>Dominikia duoreactiva</i></b> sp. nov. and <b><i>Dominikia difficilevidera</i></b> sp. nov., two new species in the Glomeromycota
Bibliographic record
Abstract
Two new species of arbuscular mycorrhizal fungi (AMF) of the recently erected genus Dominikia (Glomeromycota) are described based on their morphology and phylogenetic analyses of SSU–ITS–LSU sequences. The distinctive morphological characters of the first species, Dominikia duoreactiva sp. nov., is the formation of loose clusters with yellow-coloured, 30–70 μm diameter spores having a three-layered spore wall, of which layers 1 and 3 stain in Melzer’s reagent. The second species, Dominikia difficilevidera sp. nov., is distinguished by its hyaline, 31–45 μm diameter spores, which arise mainly singly and have a three-layered spore wall, of which layer 1 is thicker than the structural laminate layer 2, and layer 3 is flexible to semi-flexible. Both species were originally associated with maritime dune plants; D. duoreactiva comes from the Giftun Island, Egypt, Africa, and D. difficilevidera from the Słowiński National Park, Poland. Based on available data, we suggest D. duoreactiva occurs rarely in the world, and D. difficilevidera has a worldwide distribution, but it either occurs infrequently or has been overlooked or lost during spore extraction from soils of many sites because of its extremely small and hyaline spores. A method allowing the extraction of even the smallest spores of AMF, but observable under a dissecting microscope, is described.

How this classification was reachedexpand
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 itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
