Webcap sp.

Growing under a small tree (I don't know what species of tree it was). Two fruit bodies growing next to each other. Smell and taste weren't distinct, just regular and mushroomy... Maybe a Cortinarius like C. uliginosus? Growing near a waterlogged area but not necessarily waterlogged where the fruit bodies were. 'downstream' from a coniferous plantation where lots of winberries (bilberries) were growing (does this indication poor acidic soil?). Stem was hollow
