Saelania glaucescens (Hedwig) Brotherus

Family: Ditrichaceae

Status: Native

Synonyms:
Didymodon trifarius(Hedwig) Rohling

Saelania glaucescens at first glance looks like Ceratodon purpureus with a fungal infection. The blue-green color is diagnostic in the field. The leaf morphology is nearly identical otherwise, all the way down to the occasionally double-toothed margin and the irregular toothing at the apex. The cells of the lamina are clear and mostly quadrate. The filamentous or globular material on the leaves that imparts the color to them is apparently a diterpene chemical and not a fungus or cyanobacteria. The sporophyte characters differ from the sporophyte of Ceratodon but we have yet to find reproductive plants. Saelania glaucescens is found under shady rocky overhangs on soil or rock.
