Conotrema and Conotrema urceolatum
This page provides information about lichens in the genus Conotrema, particularly focusing on Conotrema urceolatum. These lichens are part of the fascinating world of symbiotic organisms, where fungi and algae (or cyanobacteria) live together in a mutually beneficial relationship.
Considerations for Pets
- The text describes Conotrema thalli as appearing like washes of white or pale grey paint sprinkled with tiny apothecia, which are the fruiting bodies of the lichen. These small parts might be of interest to curious pets if accessible.
Scientific Classification
- Genus: Conotrema Tuck.
- Species: Examples include Conotrema urceolatum (Ach.) Tuck. and Conotrema populorum.
- Kingdom: Plantae (though lichens are not plants themselves, this is the kingdom referenced in the text)
- Family: Stictidaceae
- Synonyms: Stictis urceolatum (Ach.) Gilenstam is listed as an alternative name for Conotrema urceolatum. T. harmandii PIT. is noted as Conotrema harmandii (PIT.)
Common Names
- Conotrema lichens are generally referred to as "Conotrema Lichen."
- Conotrema urceolatum is known as "Urceolate Conotrema Lichen" and "Can-of-worms Lichen."
Distribution and Habitat
- Conotrema species are found growing on the bark of trees.
- Conotrema populorum is noted as a rare and red-listed lichen.
- Mentions include occurrences in Eastern Canada, Aton Forest, and the University of British Columbia Herbarium collection. One species is noted as neotropical.
Morphological Characteristics
- Conotrema thalli appear as "washes of white or pale grey paint" with "tiny apothecia."
Ecological Role
- The text mentions that Conotrema populorum is a rare and red-listed lichen, indicating its conservation status and potential vulnerability.
Interactions with Other Organisms
- The text mentions that Conotrema is a lichenized species, meaning that its fungal partner lives in symbiosis with an alga.
