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

Ring count

Required integer input.

Days per ring

Elapsed days represented by one ring under the observed growth conditions.

Estimate elapsed growth time from colony zonation rings and an experimentally established time per ring; one ring does not inherently equal one day. 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]

Estimated age (days)

The resulting estimated age 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.

• Basidia Spored Checker

  Check whether the observed spore count per basidium is four. The tool does not infer sterigma count because aborted or immature spores can make that count differ from observed spores.

• Durham Gas Detector

  Record whether gas is trapped in a Durham tube; this detects gas production but does not replace a separate acid or growth reading.
