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

Radius extension (m)

Required number input.

Observation years

Required integer input.

Estimate average annual radial spread of an Armillaria genet from measured radius extension over a whole-year observation interval. 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]

Annual spread radius (m/year)

The resulting annual spread radius returned as a number.

• 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.

• Radial Growth Rate

  Calculate radial mycelial growth in millimetres per day from the change between initial and final colony radius over elapsed time.

• Rhizomorph Extension Rate

  Record the daily extension rate of a rhizomorph from measured extension over elapsed days.

• Layer Note Generator

  Generate a descriptive note for a recorded culture layer observation.
