Found on the ground under alders.
On a rock near the shore in a salt marsh.
On rock outcrop. Not tomentose from what I could see. Tiny coralloid phylocladia. Cephalodia external. Stalks less than 3cm.
On alder. Possibly H. enteromorpha, based on the presence of short side buds, lack of regular dichotomous branching. I did not do spot tests.
