Leptobryum pyriforme (Hedw.) Wilson var. flagelliferum Holz.
Leptobryum pyriforme is a small moss of damp streamsides at upper elevation. It is most easily recognized in the field by the obviously pear shaped capsules with a very constricted neck on a moss with very elongate grass-like upper leaves. Under the microscope, the upper leaves are linear and grasslike and up to 5 or 6mm long. The leaves lower on the stem are much shorter and lanceolate. The costae are very pronounced on the lower leaves, broad and percurrent to excurrent. On the upper leaves, the costa is difficult to recognize at times as it takes up much of the width of the leaf and may not be colored differently than the cells at the periphery. The leaf axils of the leaves frequently have hairs with one or two bright red cells at the base. The rhizoids sometimes bear brood bodies, also known as rhizoidal tubers,
that are multicellular, round to ovoid, smooth and dark reddish brown.
