SHORT NOTE Membranomyces species are common ectomycorrhizal symbionts in Northern Hemisphere forests
Bibliographic record
Abstract
Jülich consists of two described species of resupinate (crust-like) basidiomycetes. Previous studies indicated that Membranomyces falls within the Clavulinaceae, but the phylogenetic position of the genus has not been fully resolved. Membranomyces species were thought to be sap-rotrophic until 2003 when Tedersoo et al. detected Membra-nomyces delectabilis on ectomycorrhizal roots of Populus and Picea. Membranomyces was previously known only from collections made in eastern Canada and Europe. We recently sequenced the ITS rDNA barcode region from Scandinavian herbarium specimens identified as M. delec-tabilis and Membranomyces spurius. Phylogenetic analyses of these sporocarp sequences and similar environmental sequences indicated that Membranomyces is more diverse than previously thought and forms ectomycorrhizas with hosts from a diverse range of plant families in many north temperate ecosystems.
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.
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.
