 Inocybe saliceticola grows in a mycorrhizal association with willow ( Salix ) . Precise favoured species are unclear ; at least one of the tea @-@ leaved willow ( Salix phylicifolia ) or the dark @-@ leaved willow ( S. myrsinifolia ) is a possible symbiont , while other trees that the species has been found near include the bay willow ( S. pentandra ) , the grey willow ( S. cinnerea ) , the grey alder ( Alnus incana ) and species of birch ( Betula ) . I. saliceticola is found most typically in moist thickets or woodland close to shores , but recordings have also been made in other moist habitats . Mushrooms are encountered on the ground , growing from detritus or amongst moss , such as the heart @-@ leaved spear @-@ moss ( Calliergon cordifolium ) , the spiky @-@ bog moss ( Sphagnum squarrosum ) and species of Mnium . They are typically near plants such as the tufted loosestrife ( Lysimachia thyrsiflora ) , the creeping buttercup ( Ranunculus repens ) , the common marsh @-@ bedstraw ( Galium palustre ) , the purple marshlocks ( Comarum palustre ) and the purple small @-@ reed ( Calamagrostis canescens ) , and share the habitat with other Inocybe , including I. acuta and I. lacera var. helobia .
