Description - Plants mostly medium-sized, slender, in pendent, ± lustrous, bright to yellowish green, usually dense colonies; stems creeping to pendent, to ca. 40 cm long, but locally usually ca. 10 cm, freely branched, in young material often ± pinnate, the branches seemingly indeterminate and capable of becoming stems. Leaves conspicuously seriately ranked, erect-spreading to spreading from the insertion, obovate to oblong-obovate, cuspidate, concave above, ± cordate at base, (0.8) 1.3-1.6 x 0.2-0.5 mm; margins serrulate almost throughout, broadly incurved above, mostly plane below; costa none or short and single and ending below 1/4 the leaf length; cells long-hexagonal, 40-60 x 1-3.5 µm, often becoming somewhat shorter near base of the cusp; alar cells extending up the margins in 3-4 rows and across the insertion by (6)8-10 rows but not approaching the costa, often yellow across the entire insertion. Setae ± roughened above, 3-4 mm long, curved; capsules 1.1-1.4 mm long.

Discussion
The type of the most widely used name for this taxon, Ortho- stichella/Pilotrichella pentasticha, has recently been examined by Bruce Allen and it is an Orthostichidium/Hildebrandtiella.
