Mosses are often overlooked; however, they are important for soil-atmosphere interfaces with regard to water exchange. This study investigated the influence of moss structural traits on maximum water storage capacities (WSCmax) and evaporation rates, and species-specific effects on water absorption and evaporation patterns in moss layers, moss-soil-interfaces and soil substrates using biocrust wetness probes. Five moss species typical for Central European temperate forests were selected: field-collected <italic>Brachythecium rutabulum</italic>, <italic>Eurhynchium striatum</italic>, <italic>Oxyrrhynchium hians</italic> and <italic>Plagiomnium undulatum</italic>; and laboratory-cultivated <italic>Amblystegium serpens</italic> and <italic>Oxyrrhynchium hians</italic>.
WSCmax ranged from 14.10 g g−1 for <italic>Amblystegium serpens</italic> (Lab) to 7.31 g g−1 for <italic>Plagiomnium undulatum</italic> when immersed in water, and 11.04 g g−1 for <italic>Oxyrrhynchium hians</italic> (Lab) to 7.90 g g−1 for <italic>Oxyrrhynchium hians</italic> when sprayed, due to different morphologies depending on the growing location. Structural traits such as high leaf frequencies and small leaf areas increased WSCmax. In terms of evaporation, leaf frequency displayed a positive correlation with evaporation, while leaf area index showed a negative correlation. Moisture alterations during watering and desiccation were largely controlled by species/substrate-specific patterns. Generally, moss cover prevented desiccation of soil surfaces and was not a barrier to infiltration. To understand water’s path from moss to soil, this study made a first contribution.
