Detailed information on fruiting phenology provides new insights on wood-inhabiting fungal detection

Fruiting phenology traits may have a large effect on the detection of fungal species. Detailed studies considering these biologically important traits are, however, surprisingly scarce. We conducted a rigorous fruit body monitoring of wood-inhabiting fungal occurrences over one fruiting season. Taxon-specific longevity of the fruiting was different between different morphological groups. This was mainly due to agaric fruiting being shorter than other groups. Different number and timing of surveys are needed to detect the majority of the fruiting taxa of different wood-inhabiting fungal groups.
