I am unable to name this plant. It is not M. longirostre (as I once thought), nor is it M. Brevicaule. Could it be an undescribed taxon?
Other identifications
Identification
Determined name:
Macromitrium cf. longirostre
Determiner:
Allan Fife
Identification date:
2012-01 (Verbatim: Jan. 2012)
Preferred name:
Macromitrium longirostre (Hook.) Schwägr.
Active:
no
Identification type:
Determination
Note:
This material has the distinctive habit of Macromitrium cf. longirostre. The laminal cells are smooth but bulging and the mid costa has both abaxial and adaxial stereid bands. However, I cannot detect any bistratose regions in the upper laminal cells, which is unusual for Macromitrium longirostre. But I don't know what other species it could be.

Specimen notes
Supplementary remarks:
Leaves oblong-lanceolate, mostly c. 1.8–2.3 mm, cuspidate.
Costa undulate in upper leaf, mostly ending below the base of cusp.
Upper laminal cells smooth but bulging, subquadrate, very uniform in shape (but more irregular near costa), c. 8 × 8 µm; not forming bistratose areas.
Basal laminal cells short rounded-rectangular, mostly 9–15µm long
No gemmae seen.
The very short basal laminal cells and lack of bistratose laminal areas suggest that this has nothing to do with M. longirostre (although in habit it is very like this species).
Nothing to do with M brevicaule
