Bruchia

Schwägrichen

Sp. Musc. Frond. Suppl. 2(1,2): 91. 1824 ,.

Etymology: For Philipp Bruch, 1781–1847, German pharmacist and bryologist
Treatment appears in FNA Volume 27. Treatment on page 434. Mentioned on page 433, 437.

Leaves not contorted when dry, lanceolate to linear-lanceolate from a somewhat broadened ovate or oblong base, 1–2 mm, apex acute to acuminate, margins entire or serrulate; costa subpercurrect to shortly excurrent; distal laminal cells short to long-rectangular. Perichaetial leaves little different from cauline to distinctly larger and somewhat sheathing. Seta short, 0.3–0.4 mm. Capsule immersed to short-exserted, pyriform or obovate, neck weakly to strongly inflated, obovate, tapering, or short-cylindric; peristome and operculum not differentiated. Calyptra mitrate. Spores rather large, 25–45 µm, papillose, spinose, reticulate, or pitted.

Distribution

Worldwide, mainly in the temperate zones

Discussion

Species 17 (10 in the flora).

The taxonomic concept for Bruchia follows that of A. E. Rushing (1986). The large percentage of species that are endemic to the flora area may indicate an overly narrow species concept for the genus held by past monographers. The protonema of some species appears persistent. Bruchia bolanderi and B. vogesiaca approach Trematodon in size and appearance of sporophyte but the capsules are cleistocarpic.
