Layered Cup

Peziza varia

Also known as Spreading Brown Cup Fungus, Palomino Cup, Recurved Cup, Common Cup Fungus

Layered cup fungi produce brittle, saucer- to cup-shaped fruiting bodies that often become contorted and wavy as they mature in dense clusters. They act as essential saprotrophs, breaking down rotting hardwood logs, damp sawdust, rich soil, and even moist human materials like wet drywall or basement carpet. When disturbed by a stray breeze or a gentle tap, a mature cup can discharge thousands of microscopic spores at once in a faint, visible puff of white mist.

Why interaction risk is low
Many wild fungi have toxic look-alikes; never eat wild fungi based on app identification alone.
Responsible observation
  • Observe Spore Puffs: Gently blowing on a fresh, mature cup can trigger a visible cloud of spores releasing all at once.
  • Examine Tissue Layers: Inspecting a torn cross-section under a hand lens reveals the distinct multi-layered flesh characteristic of the species.
  • Indoor Inspection: Finding these fruiting indoors indicates chronic dampness or active water damage in nearby wood or drywall.
