Bacterial epibionts and endolichenic actinobacteria and fungi in the Lower Devonian lichen Chlorolichenomycites salopensis
چکیده انگلیسی


- Chlorolichenomycites salopensis was recovered from Lower Devonian Lochkovian strata.
- It is the oldest known green algal lichen with stratified, dorsiventrally organized thallus.
- We found bacteria on its surface and actinobacteria and nonlichenized fungi in its interior.
- Endolichenic actinobacteria and fungi are very common and widespread in extant lichens.
- Their occurrence in a 415 Myr old thallus fragment supports the view of a long cohabitation.

The charcoalified fragment of the dorsiventrally organized, internally stratified presumed green algal lichen Chlorolichenomycites salopensis from the Lower Devonian Lochkovian strata in the Welsh Borderland carries bacterial colonies on the upper surface, i.e. the cortex, and actinobacterial filaments in the medulla underneath the photobiont layer. Moreover relatively thin hyphae of presumed endolichenic fungi were found. As in extant lichens, which are best regarded as consortia with an unknown number of participants, this internally stratified, fossil thallus fragment of a presumed green algal lichen harbours a diverse microbial community.
