Byssoporia terrestris is an ectomycorrhizal polypore with resupinate sporocarp with a wide distribution in the northern hemisphere, a large population size and range of hosts. It is considered to have a stable population and is therefore assessed as Least Concern (LC).
Only species in the Byssoporia genus, established based on morphological characteristics (Larsen and Zak, 1977).
Wide distribution in the Northern hemisphere, mainly recorded in in Europe and North America, but has also records from Asia (Turkey and Far East Russia).
Byssoporia terrestris is is widely distributed with many records from the northern hemisphere (GBIF 2024). It is nationally red-list assessed as LC in Finland, Norway and Sweden (Hyvärinen et al 2019; Artsdatabanken 2021; SKU Artdatabanken 2020). being a species forming inconspicous corticoid sporocarps, it is commonly overlooked. Since the species is usually found in old forests, it may be under some decline in population size due to a decrease in area/quality of habitat. However, this is difficult to quantify and is not expected to be a considerable decline at a global scale given the large area of potential habitat and range of hosts.
Population Trend: Uncertain
Byssoporia terrestris is a common and widespread ectomycorrhizal fungus forming resupinate sporocarps on branches and rotten wood, usually in old forests. It is mycorrhizal with multiple conifers and broadleaved trees (Larsen and Zak, 1977; Artdatabanken, 2020; Brandrud et al. 2021). Despite widely distribted, it is neither encountered frequently as sporocarps and as DNA-identified mycorrhizas or eDNA.
No significant threats have been identified at a global scale, though the clearing of old forests in some regions mav temporary present a threat to local populations of B. terrestris (SLU Artdatabanken, 2020).
No specific conservation measures are needed. Main plant trees are assessed as Least Concern by the IUCN Red List of Threatened Species.
Reserach into its ecology and population dynamics is desirable. Potentially also to investigate if old records specimens reported from Brazil may correspond to the B. terrestris (GBIF 2024).
