Vein Network in Forest Litter

On a cool, shaded forest floor, a pale yellow network spreads across damp leaves and wood. It grows over fungi, yeasts, and bacteria and absorbs them.

In the picture

  1. Pale yellow vein-like strands: a branching network spreading over a wet leaf
  2. Small mushroom caps: fungi growing from the fallen log
  3. Creamy yeast colonies: moist patches on rotting bark
  4. Minute pale specks: bacteria scattered in the shaded leaf litter

Examples

  • A damp compost heap where moulds and bacteria break down leaves
  • Yeast in bread dough feeding on sugar and making it rise
