Fungus
Saccharomyces eubayanus
Saccharomyces eubayanusSaccharomyces eubayanus thrives on the bark and fungal galls of southern beech forests in cold temperate climates. It reproduces primarily through asexual budding, capable of efficient fermentation at temperatures near freezing where warmer-adapted yeasts become dormant. Its natural hybridization with ale yeast centuries ago produced modern cold-tolerant lager brewing strains.

Interaction riskLow
- Low
- Moderate
- High
- Very high
- Why interaction risk is low
- Many edible mushrooms have toxic look-alikes; never eat wild fungi based on app identification alone.
Responsible observation
- Observation: View living cellular colonies using brightfield microscopy at 400x or 1000x magnification.
- Culturing: Grow samples on malt extract agar at cool temperatures around 10 to 15 degrees Celsius.
