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

Maximum growth temperature (°C)

Required number input.

Check whether the reported maximum growth temperature is at or below 20 °C; maximum temperature alone cannot distinguish psychrophiles from psychrotolerant organisms. 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]

Maximum at or below 20 °C

The resulting maximum at or below 20 °c returned as a boolean.

• 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.

• CO2 Pinning Trigger

  Check whether measured carbon dioxide is at or below a caller-selected fruiting threshold; CO₂ alone does not determine whether pinning should begin.

• Cardinal Temperature Recorder

  Record minimum, optimum, and maximum fungal growth temperatures after validating their order; the values themselves determine whether a thermophile label is appropriate.

• 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.
