Chaenothecopsis: A Glimpse into the World of Lichen-Associated Fungi
Chaenothecopsis is a genus of fungi often associated with lichens. They are sometimes parasitic or commensal on lichens, free-living algae, or found on wood. This makes them a fascinating group for ecological study.
Taxonomy and Nomenclature
- Scientific Name: Chaenothecopsis Vain.
- Rank: Genus
- Family: Mycocaliciaceae
- Order: Mycocaliciales
- Class: Eurotiomycetes
- Phylum: Lichens (Note: While traditionally studied with lichens, Chaenothecopsis itself may not always be lichen-forming.)
- Synonyms: Some species have been reclassified. For example, Calicium debile is a synonym for Chaenothecopsis debilis, and Chaenothecopsis pusilla curtisii is a synonym for asikkalense Vainio.
Distribution and Habitat
Chaenothecopsis species are found in various regions globally, including:
- The Greater Sonoran Desert Region
- Norway
- China (Yunnan)
- Colombia (Huila)
- Germany
- Bdmeren Forest area
- British Columbia (Clearwater Valley, Dawson Falls)
They often inhabit dead wood or are associated with other lichens and algae.
Ecological Role
Chaenothecopsis species exhibit diverse ecological roles:
- Parasitic/Commensal: Many species are parasitic or commensal on lichens.
- Substrate Decomposition: Some species are found on decaying wood (lignum).
Morphological Characteristics
- Chaenothecopsis is characterized by a stalked capitulum lacking a mazaedium, and short asci.
