Hypogymnia physodes (L.) Nyl., 1896
Alberta Most Abundant
| Common name | Hooded Tube Lichen | |
|---|---|---|
| Code | HYPOPHY | |
| Field Characters | Small to medium-sized, leafy chlorolichens. Thalli loosely appressed to slightly ascending, slightly stiff. Lobes hollow, branching alternately, with rounded margins. Upper surface blue-grey to creamy white, dull to slightly shiny. Lower cortex black, lacking rhizines. Soredia present, in soralia forming on the underside of terminal, hooded lobe tips. Apothecia very rare, when present laminal, on short stipes, with brown discs. | |
| Similar species & genera |
Hypogymnia tubulosa: soralia form on the top of lobe tips.
Parmelia: with experience these two genera are easily discriminated – Parmelia has hammered, often angular lobes and abundant rhizines. Because they both have some super common species that often grow overtop each other they often are confused by beginners. |
|
| Ecology | Epiphytic or on downed wood, rarely saxicolous. Common across all forested regions, occasional in the parkland and rare in the grassland. | |
| Chemistry | Upper cortex PD+ pale yellow or PD-, K+ yellow, C-, KC- or rarely KC+ yellow, UV- (atranorin, chloroatranorin). Medulla K-, C-, KC+ orange-red, PD+ orange-red (physodic acid, 3-hydroxyphysodic acid, physodalic acid, protocetraric acid, ±2′-0-methylphysodic acid). AB collections TLCed: 16. | |
