Andreaea: A Genus of Unique Mosses

The genus Andreaea encompasses a fascinating group of mosses, commonly referred to as lantern mosses or granite mosses. These mosses exhibit several unique characteristics that set them apart from other members of the bryophyte world.

Scientific Classification

  • Genus: Andreaea Hedw.
  • Class: Andreaeidae
  • Family: Andreaeaceae
  • Order: Andreaeales
  • Division: Bryophyta

Nomenclature and Synonyms

  • Andreaea rupestris Hedw. is a commonly referenced species. It has the common name Black Rock-moss.
  • Andreaea petrophila Ehrh. is cited as a modern name for Andreaea rupestris.

Considerations for Pets

  • Some Andreaea species are small mosses, growing up to 3 cm, potentially posing a choking hazard for small pets if ingested.

Distribution and Habitat

  • Andreaea species are found globally, including in mountainous regions, alpine environments, and even Antarctica.
  • Specific locations mentioned include Europe (Austria, Czech Republic, France, Scandinavia) and the Scottish Highlands.
  • They are often abundant on the surface of rocks, particularly granite.

Ecological Role

  • Andreaea is referred to as a "granite-moss," indicating its common association with rocky substrates.

Morphological Characteristics

  • Andreaea rupestris can be blackish-green to black, or reddish-brown to dark brown, and can grow up to 2 cm high.
  • They form dense tufts.

Quirky Facts

  • Andreaea mosses are unique in that they lack a seta (stalk) on their sporophytes. Their capsules protrude directly above the surrounding structures.
  • Spore size and morphology are considered very important in classifying different Andreaea species.

Interactions with Other Organisms

  • UV-B radiation influences the pigmentation of Andreaea regularis.

Further Information

  • The Integrated Taxonomic Information System (ITIS) is mentioned as a resource for information on Andreaea.
  • Tropicos is another referenced database.
