This observation refers to the pair of specimens identified by Dr. Henry Beker as Hebeloma cistophilum. As the name indicates this species usually grows associated with Cistus spp. and, though I haven’t noticed them in the field, I would say that probably they can be found there, the margins of the reservoir of a dam with vegetation reduced to a Salix species and few else.

According to the references, H. cistophilum belongs to section Hebeloma, constituted by those mushrooms with cortina, that may be fugacious (reason for which I didn’t found it in this specimens), and cheilocystidia mostly ventricose.
