  • Description

    Species Description - Plants robust, yellow-green, glossy, in flat mats. Stems prostrate, irregularly branched, the branches flattened. Leaves oblong to oblong-ovate, to 2 mm long, acute or more often ± obtuse, constricted at the insertion; margins plane, denticulate above; costa short and double; cells linear, subflexuose, shorter at the extreme apex; alar cells numerous, quadrate to short-rectangular, gradually differentiated from those above. Autoicous. Setae light-yellow to yellow-orange, ca. 1.5 cm long; capsules up to 4 mm long; annulus none; operculum long-conic; exostome teeth lanceolate, reddish, on the front surface striolate below, papillose above, smooth at the apex, papillose on the back; endostome smooth to lightly papillose. Spores finely papillose, 13-15 µm.

    Gametophytically difficult to separate from E. macropodus, this species has a shorter, usually redder seta and a different peristome as reliable characters. In E. hampeanus the leaves are often widest near the middle rather than near the base; the leaf apex is commonly ± obtuse rather than consistently acute; the leaf cells are often subflexuose rather than straight; and the alar regions are better differentiated. I have not seen the type of E. flaviusculus C. Müll., but another Guatemalan specimen so-named (H-BR), also collected by Türckheim, matches Müller's description well and can be referred to E. hampeanus.
