Winter Slime Mold Hunting: Cold-Weather Species and Snowline Timing

Winter is not dead season for slime molds. In repeated community records, winter and late autumn are repeatedly productive windows, especially for cold-adapted observations.

When to check

• After moisture events during cold periods.
• During freeze-thaw transitions.
• Near receding snow edges in suitable regions.

Typical cold-season targets in this dataset

• Lamproderma-type winter observations, including iridescent forms.
• Comatricha observations in cold moisture windows.
• Nivicolous records near melting snow microclimates.

Regional caution

Snowline and freeze-thaw signals are region-dependent. Do not copy mountain timing into lowland climates without local observation logs.

Field checklist

1. Track daily temperature swings, not only average temperature.
2. Inspect twigs, grasses, and litter margins near snow retreat zones.
3. Revisit the same patch across several days.
4. Document whether fruiting survives freezing nights.

Confidence note

Cold-season productivity is a repeated trend in this source set. Species-level claims outside repeated regions should stay provisional.
