Blepharostoma trichophyllum


Blepharostoma trichophyllum is a lacey little leafy-liverwort in the family Trichocoleaceae. Like other members of the family, its leaves are filamentous. More specifically, the leaves (both lateral and underleaves) are deeply divided into 3-5 filamentous (1-cell thick) lobes, with a shared attachment site at the leaf base. The plants rarely have shoots more than 0.5 mm wide.

Habitat and Distribution

Blepharostoma trichophyllum is commonly found on decaying logs, rock faces, peat, organic soil hummocks in moist woods, and other shady sites throughout New Brunswick. Sterile shoots are often isolated among other species, while fertile shoots (those with perigynia) are most commonly found in relatively monospecific colonies.

There are 83 records of Blepharostoma trichophyllum throughout 12 New Brunswick counties: Albert, Charlotte, Gloucester, Kent, Kings, Madawaska, Northumberland, Restigouche, Saint John, Victoria, Westmorland and York.

It is widespread and frequent, but likely underreported, due to its diminutive size and the fact that it is most often collected as an associated taxon with other species; only 9 records report it as a primary taxon at the New Brunswick Museum, whereas 67 report it as an associated taxon. Additional records can be found at the Consortium of North American Bryophyte Herbaria.
