Species description:
Genus name refers to the peristome teeth that are split into two hair-like divisions. Species name refers to the long flexuose stems noted in the specimen upon which the name was based.
Reproduction:
Sporophytes frequent in summer but the vegetative plants produce brittle apical branches that probably serve in propagation.
Comments:
A closely related species, D. crispatissimum, is consistently without sporophytes, forms tall, silky turfs (to 100 mm tall, and with leaves to 10 mm long) especially on humid, calcareous cliffs and is often considered synonymous. D. crispatis
Distinguishing characteristics:
D. flexicaule is not readily separable from other species of Ditrichum based on non-microscopic features. Plants that bear brittle, stiffly erect apical branches with reduced leaves give the plants an appearance unique to this species. These forms are more frequent in open or disturbed sites. In tundra, the plants form dense tufts that become blackened within the tuft.
Habit:
Forming short turfs of erect, dark green to light green, unbranched shoots that often bear brittle branches near the apex of vegetative plants.
Similar Species:
Most species of Ditrichum, at least in some variants, can be confused with each other, even with microscopic features. See also notes under D. capillaceum.
