  • Discussion

    Conardia compacta has been reported from Mexico (e.g., Delgadillo et al., 1995; Sharp et al., 1994). It is here reported from Guatemala as well. The species is easily recognized by its small size (stem leaves 0.61.1 mm long), the often strongly denticulate basal margin of the leaf, and the usually distinct alar cell group. It differs from other small pleurocarpous mosses with single costae, such as Amblystegium species, in its relatively large axillary hairs with short upper cells (Fig. 22E); its much-branched, warty-papillose rhizoids, which are often inserted on the back of the leaf costa; and in the frequent occurrence of rhizoid initials, rhizoids, or gemmae near the leaf apex.

  • Distribution

    Mexico (2120-2590 m a.s.l.) and Guatemala (1530-2800 m). Widespread in N America, Europe, N Africa, and Kashmir. Occurs on moist or wet mineral-rich rocks or soil; close to streams, waterfalls, or hot springs; occasionally submerged. Outside the area sometimes found on rocks or soil close to the sea.
