Wine-cap Stropharia

Stropharia rugosoannulata

Also known as Garden Giant, King Stropharia, Burgundy Mushroom, Wine-red Stropharia

Wine-cap Stropharia thrives in woodchips and rich garden soils, where its expansive mycelial network actively breaks down woody mulch. Underground hyphae produce microscopic, spiky cells called acanthocytes that mechanically immobilize and digest soil-dwelling nematodes. Young fruiting bodies emerge with deep wine-red to burgundy caps that flatten and fade to a pale straw yellow with maturity, framed beneath by a thick, cogwheel-like ring.

Why interaction risk is low
Many edible mushrooms have toxic look-alikes; never eat wild fungi based on app identification alone.
Responsible observation
  • Ring Inspection: Look beneath the cap to check for the distinctive, cogwheel-patterned ridges on the annulus.
  • Spore Print: Place a mature cap gill-side down on white paper to reveal its dark purplish-black spore deposit.
  • Habitat Clues: Search damp hardwood mulch or composted garden pathways after soaking autumn rains.
