My friend found this growing sand in the dune grasses near Psilocybe azurescens and Clitocybe nuda. (rotting wood nearby).Unfortunately the specimen was lost before i could key it out. Also unfortunately i didn't get to see the base. Approx. 2" - 3" tall, cap maybe 1 - 1 1/2" across. I didn't look close at gill attachment (unfortunately!?!), but do remember they were a lovely pale shell pink. Stem and cap = Striking bright robin's egg blue color. Never seen anything like it! Help??
