A total of 78 buildings were inspected for wood biodegradation in the Latvian Ethnographic Open-Air Museum, founded in 1924, in Riga. Most of the buildings were in good condition; however, some of them sustained considerable fungal damage. Altogether 58 fungal species belonging to the phyla Basidiomycota (51), Ascomycota (3) and Protozoa (Myxomycota) (4) were identified in the wooden constructions. The majority of the fungi (64 cases) were recorded on outdoor wood, including roofs, outer walls, doorsteps, fences, poles, logs, benches, beehives, etc., whereas only 13 cases of fungal damage were observed indoors. The most common genera found in the buildings were Gloeophyllum, Athelia, Hyphoderma, Antrodia, Botryobasidium, Hyphodontia, and Mycena. The majority of the identified fungi were corticoid species (28). Nine corticoids such as Aleurodiscus fennicus, Athelia decipiens, Botryobasidium vagum, Crustoderma dryinum, Hyphoderma obtusiforme, Hyphodontia detritica, Trechispora farinacea, Tubulicrinis gracillimus, and Tubulicrinis subulatus were new for the Latvian mycobiota. The diversity of white-rot species as well as the frequency of white-rot damage prevailed over the brown-rot more than twice. The research suggests that fungal diversity and frequency in the construction wood were affected by substrate (softwood/hardwood) and decay localization (indoors/outdoors).
