Status: Native
Synonyms:
Bryum capillare Hedwig
Rosulabryum capillare is a rosulate acrocarpous moss that lacks axillary filiform gemmae. The leaves are spirally wrapped around the stem when dry. The leaves are obovate with a weak limbidium of 1 or 2 cells and usually a strongly serrulate distal margin (weak in our specimen). There are rhizoidal tubers that are the same color as the rhizoids, 200-300 microns in diameter, and not bright crimson as they are in R. torquescens. We found R. capillare at the entrance to a cave on a boulder.
We first found this species at El Malpais National Monument and more pix can be found there:
