Bryoria fuscescens (Gyeln.) Brodo & D. Hawksw., 1977
| Common name | Pale-footed Horsehair | Code: BRYOFUS
|
|---|---|---|
| Field Characters | Fruticose, hair-like chlorolichen. Brown, tufted or shrubby, rarely pendant. Branches dull, pale brown, olive-green or dark brown, sometimes with a pale base but just as often not. Branches forming angular nodes, typically acute angled. Soralia typically abundant, fissural, with farinose soredia, lacking isidia. While often desribed as lacking pseudocyphellae, B. vrangiana, which was synonymized with B. fuscescens, has linear pseudocyphellae.
Difficult to distinguish from the chemically-identical B. glabra, so sometimes treated as a species group. |

Bryoria glabra: more evenly isotomically branched, with nodes rounded, forming horseshoe-like angles, and the cortex often shiny, branches thinner, and lacking pseudocyphellae. Apparently restricted to mountain and foothills sites. | |
| Ecology | Grows on conifers, shrubs, and downed wood in most forested regions of Alberta. Largely absent from urban forests (Haughland et al. 2022). | |
| Chemistry | Soralia K-, KC-, PD+ red, UV- (fumarprotocetraric acid), cortex and medulla usually all spot tests negative in Alberta. In other regions the cortex may be PD+ red as well. | |
