Dibaeis

Dibaeis is a genus of lichenized fungi belonging to the family Icmadophilaceae. Commonly found in tropical regions, the genus currently includes 13 recognized species.

Dibaeis baeomyces

One notable species within this genus is Dibaeis baeomyces, commonly known as pink earth lichen.

Considerations for Pets

  • The text mentions that the lichen is small and can colonize bare ground. This suggests it could be found in areas accessible to pets, particularly dogs.

Considerations for Children

  • As with pets, the lichen's small size and habit of growing on the ground may make it accessible to children.

Taxonomy and Nomenclature

  • Scientific Name: Dibaeis baeomyces (L. f.) Rambold &amp Hertel
  • Family: Icmadophilaceae
  • Synonyms: Baeomyces roseus, Baeomyces fungoides, Dibaeis rosea
  • Symbol: DIBA4

Distribution and Habitat

  • Dibaeis is widely distributed in tropical regions.
  • Dibaeis baeomyces has a broad distribution, including:
    • Eurasia (Asia-Temperate, Asia-Tropical)
    • Americas (North America, including Mexico; South and Central America)
    • Oceania
  • Specifically found in areas like the White Mountains of New Hampshire, Franconia Notch, and Charles Co., Maryland, growing on soil and gravel along road cuttings and in dry woods.

Morphological Characteristics

  • Dibaeis baeomyces is a fruticose lichen.
  • The thallus is typically gray, white, or roseate tinged, crustose, smooth or powdery.
  • Fertile plants have spherical or flattened verruculose warts with a narrowed base.
  • Dibaeis is divided into two subgenera: subg. Dibaeis with stalked, clavate to capitate apothecia and fusiform to aciculate ascospores.
  • Dibaeis absoluta has pink apothecia on very short (ca. 1 mm) stalks, arising from a crustose thallus.

Ecology

  • Dibaeis baeomyces is a pioneer species that can colonize large patches of bare ground.
  • It is often found on exposed soil and gravel, such as along road cuttings.

Further Resources

  • Discover Life offers a page about the biology, natural history, ecology, identification, and distribution of Dibaeis baeomyces.
  • Observations of the species can be found in the Natural History Museum's UK Species Inventory.
  • Flora of Australia volume 58A (2001) provides information on Dibaeis.
