Hygrohypnella bestii (Renauld & Bryhn) Ignatov & Ignatova

Family: Amblystegiaceae

Status: Native

Synonyms:
Hygrohypnum bestii (Renauld & Bryhn) Holz.
Hypnum molle subsp. bestii Renauld & Bryhn
Limnobium bestii (Renauld & Bryhn) Holzinger

Hygrohypnella bestii has straight, short and squatty leaves that are less than 1.5x long as wide. The best character to use to separate this species from the many other similar members of Hygrohypnum is the length of the marginal laminal cells. They are so long, in fact, that it can be difficult to tell where they start and stop. They can be well over 100 microns long. Hygrohypnella bestii, like other members of the genus, is found in streams and wet seeps. It is known from one collection in New Mexico that was identified by Jamieson, who wrote the genus treatment for Flora of North America. The specimen photographed here was collected by W.R. Norris in Montana.
