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

Spores per basidium

Required integer input.

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. 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]

Is four-spored

The resulting is four-spored returned as a boolean.

Observed spore count

The resulting observed spore count returned as an integer.

• 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.

• Ascus Spore Count

  Report whether the observed count is exactly eight spores per ascus without imposing an arbitrary upper limit on other observations.

• 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.

• 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.
