Usually fungal and algal colonizers are faster, but after only a few years, moss growth may start if conditions are favorable. The primary aim of the project between the "Royal Botanic Garden Edinburgh (RBGE)" and the Fraunhofer-Institute for Building Physics IBP was to obtain DNA barcodes of samples that are involved in the primary colonization of building surfaces (masonry), with special emphasis on the genus Schistidium.enjournal article
