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

Substrate dry mass (kg)

Required number input.

Supplement percent of dry substrate (%)

Required number input.

Calculate supplement mass as a percentage of dry substrate mass; this is a dry-substrate basis, not percentage of the final combined mixture. 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]

Supplement mass (kg)

The resulting supplement mass 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.

• Amatoxin Cap Assay

  Classify a reported amatoxin assay result as a potential lethal-toxin risk. Non-detection does not establish that a mushroom is edible or free of other toxins, and this tool does not replace laboratory or poison-control interpretation.

• Biological Efficiency %

  Compute biological efficiency percent as fresh mushroom mass divided by dry substrate mass times one hundred.

• 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.
