Stereocaulon paschale is a species of lichen belonging to the family Stereocaulaceae.[2]
It has a cosmopolitan distribution.[2]
In Iceland, it has the conservation status of a vulnerable species (VU).[3]
Ecology
Stereocaulon paschale is host to some lichenicolous fungi which infect various parts of the thallus. Most of these fungi have a Holarctic distribution. These fungi include:[4]
- Arthonia stereocaulina, Infects the phyllocladia but rarely causes disease.
- Catillaria stereocaulorum, Mainly infects the phyllocladia, which can become swollen and dark. It is common in the Arctic.
- Cercidospora stereocaulorum, Infects phyllocladia and sometimes on stems, cephalodia and apothecia.
- Endococcus nanellus, Infects phyllocladia and sometimes on stems, cephalodia and apothecia. Often found in discolored apothecia but does probably not cause the discoloration.
- Lasiosphaeriopsis stereocaulicola, Usually found at the stem base which can turn brown but no other symptoms are known.
- Lichenopeltella stereocaulorum, Most often found on stems. This species was only discovered in 2010.
- Opegrapha stereocaulicola, Infects stems which may become darker.
- Phaeosporobolus alpinus, Commensal. Most commonly found on species of Pertusaria or Ochrolechia.
- Polycoccum trypethelioides, Produces galls on stem which change colour with time turning cinnamon colour or brown.
