Ruby Bonnet

Cruentomycena viscidocruenta

Also known as Ruby Mycena

Ruby bonnets produce tiny, brilliant crimson caps that glisten with a sticky, viscid coating in damp austral woodlands. Growing solitary or in small clusters on decaying bark, twigs, and leaf litter, these fungi act as important saprotrophs by decomposing organic matter. Their intense red coloration and dark red stems make them a striking find along moist forest floors in Australia and New Zealand.

Why interaction risk is low
Wild fungi have toxic look-alikes; never ingest wild mushrooms based on identification apps alone.
Responsible observation
  • Look for Moisture: Search on damp, fallen branches and leaf litter after recent rainfall.
  • Inspect the Cap: Gently check for the sticky, slimy coating characteristic of young caps.
  • Observe Undisturbed: Leave fruit bodies intact to allow natural spore dispersal.
