Garry Fletcher found this moss on a morning seashore foray along the shores of Parry Bay, at a seepage area above a rock beach. When he brought the moss back to the BioBlitz headquarters for identification, Steve Joya recognized it. The moss team made a detour in the afternoon to see Crumia in situ. “We only have a handful of collections from B.C.,” says Steve, “and these are mainly from islands in the Strait of Georgia area plus one from Limestone Island in Haida Gwaii…. I am not aware of any modern collections from Vancouver Island proper, so the Metchosin record was interesting.
Wilf Schofield, the late doyen of BC mosses, extracted this moss from a motley classification group and moved it to its own genus, naming it after the famous moss biologist, Howard Crum.”
Habitat and ID:

Crumia latifolia normally occurs on seepy shaded calcareous outcrops. The location on the Taylor bluffs is not normally considered to be calcareous.. The seeps originate from a deep glacial till layer.

I returned in the summer and took more pictures of the site and a specimen closeup:
Crumia can be separated from Tortula, a similar species, by the row of swollen, orange colored marginal cells on the leaves.
