The walls of the Cathedral of Coimbra are destroyed by a fungus previously unknown to scientists.
The old cathedral in the city of Coimbra is a unique architectural monument of the XII century. This is the only Romanesque church in the country, well preserved from the time of the expulsion of the Arabs from the country. The cathedral has stood for many years and survived many wars. But now, in peacetime, he is in grave danger. Her name is Aeminium ludgeri, a new type of mold.
The hitherto unknown mushroom refers to the order of Capnodiales. Representatives of this taxon (rank of biological classification – Ed.) Are highly resistant to adverse environmental conditions. They are able to withstand severe drought, low temperatures and high salt concentrations. Such mushrooms are a big problem for architectural monuments: they slowly destroy the walls of buildings with their hyphae threads and emit substances that provoke corrosion.
Biologists suggest that the new fungus lives in the walls of the building for a very long time. He probably arrived in Coimbra, along with building materials for the construction of the cathedral. It is possible that Aeminium ludgeri has already spread throughout the Iberian Peninsula.
