Ies, and associated photoautotrophs. Environmental conditions in the kind locality: Discharge (L s-1): 3.five, Temperature ( C): 5.three, conductivity ( cm-1): 62, alkalinity ( q L-1): 311, pH: six.six, nitrate (mg L-1): 1.two, TP ( L-1): 7 (see  for more details). As issues photoautotrophs, within this incredibly shaded source the competitive balance involving huge groups (algae, lichens, bryophytes, and vascular plants) is clearly favorable for the mosses, which cover virtually all of the lithic substrata [dominance of Brachythecium rivulare W.P. Schimper, each submerged and, in significant portions, emerged, and also a particular relevance of Plagiomnium undulatum (Hedw.) T.J. Kop. and Rhizomnium punctatum (Hook.) T.J. Kop.]. Vascular plants aren’t abundant (as cover), and Adenostyles glabra (Miller) DC. and Saxifraga rotundifolia L. may be talked about among them. In terms of cover, bryophytes are followed by lichens. These involve two species which are hardly ever reported in Italy: Verrucaria madida Orange, an amphibious species in frequently flooded web pages on siliceous rocks, frequently in association with other aquatic lichens and bryophytes, and Verrucaria aquatilis Mudd., typical both in springs and along streams, in conditions of perennial/frequent submersion. Benthic macroalgae are uncommon and mainly represented by the red freshwater alga Hildenbrandia rivularis (Liebmann) J. Agardh, which can be characteristic of shaded springs with well-buffered waters and medium-high conductivity.
