Lopidium concinnum

Lopidium concinnum is the only species within that genus found in Tasmania, from which the Dicksonia tree fern it was recorded on in Swansea originated. It is said to be a relatively common rainforest epiphyte in Tasmania growing on the caudex of tree ferns. The whitish leaves, which have a distinctive bleached appearance, are structurally reminiscent of the more familiar Fissidens, but are in fact three-ranked, with a row of under-leaves forming the third rank.

Site notes:

Wyevale, Swansea, 20-Dec-19 (BS): Lopidium concinnum was the most conspicuous of four alien bryophytes noted on an imported Dicksonia antarctica 'trunk'. Heteroscyphus fissistipus was the only other species identified.
