Use this mycology utility to record or consistently classify a stated fungal morphology, culture, ecology, assay, cultivation, or microscopy observation for later expert review.

Mantle thickness (µm)

Required number input.

Thin maximum (µm)

Required number input.

Thick minimum (µm)

Required number input.

Grade ectomycorrhizal mantle thickness using thin and thick boundaries supplied for the host, fungus, tissue section, and study protocol. The tool evaluates the supplied inputs together and returns the named outputs below; it does not infer omitted operating conditions or change the units shown.^[1]

Mantle grade

The resulting mantle grade returned as a string.

• Fungal identification and susceptibility interpretation depend on specimen quality, developmental stage, medium, temperature, microscopy, molecular evidence, validated breakpoints, and taxonomic context. Pattern-based output is not an edibility, toxicity, infection, or treatment determination.
• Use finite inputs in the displayed units and preserve more precision than the final presentation requires. Independently verify safety-critical, financial, compliance, or production decisions.

Preserve images, specimen and culture metadata, method and reference standard, use multiple characters or molecular confirmation, and refer clinical or poisoning questions to qualified services.

• Hartig Net Grade

  Classify Hartig-net penetration depth using study-specific superficial and deep boundaries supplied for the host, fungus, and sectioning method.

• Sclerotium Size Class

  Classify sclerotium diameter using caller-supplied size boundaries appropriate to the species and measurement protocol.

• Clearance Zone Rater

  Rate a cellulose-clearance zone using thresholds supplied for the assay protocol; category cutoffs vary with media, organism, and incubation conditions.
