Xanthoparmelia wyomingica (Gyeln.) Hale, 1974

| Code |
XANTWYO | ||
| Field Characters | Medium-sized, leafy chlorolichen. Thalli typically loosely attached throughout. Lobes typically narrow, convex, grasping, with crenulate margins, branching irregularly. Upper surface pale yellow, without maculae. No vegetative propagules present. Lower cortex typically brown to black, with relatively abundant, simple to sparsely branching rhizines concolorous with the lower cortex, that are largely hidden from sight. Apothecia rare. | ||
| Similar species |
Xanthoparmelia chlorochroa: lobes inrolled, forming tubes, wider, thalli vagrant.
Xanthoparmelia camtschadalis: lobes typically flat with inrolled margins, vagrant to loosely attached, maculate. |
||
| Ecology | Mostly terricolous on mosses, soil or litter, more rarely saxicolous. Most common in the grasslands, occasional in the mountains and southern parklands. | ||
| Chemistry | Upper cortex PD+ pale yellow or PD-, C-, KC+ yellow, UV- (usnic acid). Medullary chemistry complex, variable and apparently not a good taxonomic trait, always UV-, may be PD- or PD+ yellow to red, K- or K+ yellow to dark rusty red (±norstictic acid, ±salazinic acid, plus accessories). AB collections TLCed: 5. | ||
| Molecular support |
Low at the species level. Multiple studies have found that historical morphological and chemical traits do not correspond well to molecular clades (Leavitt et al. 2011a, b), and preliminary analyses of limited AB sequences also show this species occurring in multiple clades. Until more extensive molecular work is done, we continue to follow historical morphological species delimitation. | ||
