Schistidium rivulare (Bridel) Podpera



Family: Grimmiaceae

Status: Native

Synonyms:
By var.

Schistidium differs from Grimmia in that the columella falls from the capsule with the operculum. Schistidum rivulare is usually found in streambeds or in the splashzone of flowing water. The leaves usually have no hairpoints and are generally lanceolate to ovate. The perichaetial leaves are much larger than leaves lower on the stem and are more likely to have hairpoints when they are present. The leaf margins are revolute and the upper margin is coarsely knobby. The costa reaches the apex and is keeled towards the apex. The plants are usually fertile with cup shaped capsules that are immersed in the perichaetial leaves.
