Notes:
Epipterygium sp. nov. or a Bryum unknown to me. I doubt this material a Bryum, as I previously had named it; it does not belong to the B. erythrocarpum complex, noting the narrow leaf base, thin-walled laminal cells. It could possibly belong to B. capillare s.l. but the leaves which are not at all twisted when dry would seem to preclude such a relationship. In general, the very thin-walled and elongate upper laminal cells cause me to think this is not a Bryum.The distinct leaf border precludes placement in Pohlia.Could it be an Epipterygium despite lack of dimorphic leaves? In many ways it is very similar to E. tozeri, but it differs from that species (and seemingly all Epiterygiums) by having mostly shortly excurrent costae. It is NOT E. opararense.Plants very lustrous when dry, somewhat irridescent, tinted red throughout or pale green in upper portions. Stems 2-5 mm. Leaves elliptic from a strongly narrowed base, widest at or near middle, shortly acuminate,entire or denticulate near apex, in upper portions of stem 2.0-2.7 X 0.7-0.85 mm, smaller on lower stem, strongly bordered, not decurrent. Median leaf cells rhombic-hexagonal mostly 90-120 (-135) X 18-24 um, 4-6:1 very thin-walled; marginal cells storngly differentiated, longer and thicker-walled, forming a distinct unistratose border 2-4 cells wide at mid-leaf and extending to leaf apex; costa mostly shortly excurrent but often shorter, especially in small leaves. Rhizoids red-brown, coarsely papillose-insulate. Rhizoidal tubers numberous, oblong or irregular, mostly 60-90 um in greater diameter and 5-9 celled. AJFife March 1998
