Cladonia: The Cup Lichen

Cladonia, commonly known as cup lichen (or pixie cup lichen for some species), is a fascinating genus of moss-like lichens belonging to the family Cladoniaceae.

Considerations for Pets

  • Some Cladonia species have upright fruiting stalks.

Considerations for Children

  • The text references the lichen's cup-like structures, which might be of interest to children.

Scientific Classification

  • Genus: Cladonia
  • Family: Cladoniaceae
  • Kingdom: (Implied, but not explicitly stated in the text, it is likely Fungi)

Synonyms or alternative names mentioned: pyxie cup lichen (C. pyxidata), false pixie cup (Cladonia chlorophaea)

Distribution and Habitat

These lichens are often found on the forest floor, typically on logs or at the base of trees. Some species thrive in exposed subalpine sites, growing on poor soils and fallen logs. They are also described as boreal lichens, occurring across the boreal forest. One species, *Cladonia chlorophaea*, is noted as common on rotting stumps in wet lowland areas like the Olympic Peninsula. Some varieties are found along the Eagle Creek Trail, Columbia River, on rock outcrops.

Morphology and Growth

  • Cladonia species are described as moss-like.
  • They feature cup-like structures arising from a greenish-grey base.
  • Some species have funnel-shaped podetia tapering gradually towards the base.
  • The "cups" can be unbranched, round-toothed, and curled.
  • The exterior of some species is variably clothed with corticate granules.
  • Some have upright fruiting stalks.
  • Descriptions evoke "Shrek's Ears" or miniature golf-tees (podetia), albeit battered and sand-blasted.

Ecological Role

Cladonia lichens serve as a primary food source for reindeer and caribou.

Quirky Facts

  • Boiled with milk or syrup, Cladonia has been traditionally used as a remedy for whooping cough and chest ailments.
  • The text references the appearance of the pixie cup lichen as resembling miniature golf tees or Shrek's ears.
  • Some varieties have "splash cups" used for reproduction.
