UT, Colorado Plateau, 20060414
Cad's Crotch, many flowers and lichens.
Same place as yesterday. How did I miss the phlox and draba?! Also did a lichen collection spree on the conglomerate sandstone-like fins.

Genus keys clear, but again no way to guess at species.

Shepherdia rotundifolia [] [voucher]

| | STAM | | 4 + 4, alt w 8 yellow glistening gland bumps on hypanth disk |
I always thought this was honeysweet (
Tidestromia), but examining flowers I realize it can't possibly be. Fairly poetic that it turns out to be my stupid
Shepherdia after so notably mis-identifying
Olea europaea as this a few months ago! Not sure about the species, and would like to see a female plant before even signing off on the genus. However, this does look fairly promising except for my flowers being significantly too large.
Further observations:

Candelariella aurella
| | GEN | | crust lichen, on sandstone |
| | APO | | lecanorine, lots but not packed, bright yell, K-, C-, KC-, well devel smooth marg, disk bownish yell |
Xanthoparmelia plittii
| | GEN | | foliose lichen, on various rocks |
| | THAL | | smooth yell-green, black pycnidia, black marg, bot brown, rhiz present, K-, C-, KC+ yell| isidia | | v d, rounded cyl, tips blackish, some br'd |
bunched up and sorta dirty-looking |
| | MED | | white, K+ deep yell, C- |
Caloplaca flavovirescens
| | GEN | | crust lichen, on sandstone |
| | THAL | | yell to orangish dispersed areolate, K+ wine red, C- |
| | APO | | lots, packed, bright orange, convex, lecanorine, non-prominant thin ~smooth sl lter marg| disk | | sorta rough ridged-bumpy, dull |
|
Entirely plausible, but coverage is so incomplete for this genus I hate to sound confident.
Caloplaca trachyphylla?
| | GEN | | crust lichen, on sandstone and other rocks |
| | THAL | | lobed, yell-orange to red-orange, bright and striking, lobes gen < 2mm some to 3x1mm, convex, rough, areolate inside, K+ wine red |
| | APO | | same color, lecanorine |
Could also just as easily be
C. saxicola, I guess, and probably a host of other nearly identical species
Brodo doesn't even mention...
Rhizoplaca peltata
| | GEN | | umbilicate lichen, on sandstone |
| | THAL | | 10-15mm wide, bunched-up-ruffled, smooth greyish yellowish green, KC+ yell, K-, C-, marg thick and granular black, rough brownish bel w wh cracks, no rhiz |
| | APO | | lecanorine, concave, smooth, not pruinose, brownish to almost greenish |
This genus is covered in full in
Brodo, so I feel somewhat confident for a change...
Caloplaca arenaria?
| | APO | | lecanorine, packed, v thin marg, marg and disk bright red orange, rough, K+ wine red, C- |
Could it be
Protoblastenia?
Xanthoria fallax
No need to take notes: yell-orange, squamulose, K+ wine red, soralia under upturned lips... very distinctive.
Caloplaca microphyllina?
| | GEN | | crust lichen, on wood (weathered dead bare juniper) |
| | THAL | | microsquamulose to coarse granular, edges of squamules branched or granular like isidia, yellow green to yellow orange in one, yellow orange to red orange in another, K+ wine red |
| | APO | | bright orange w yellow orange marg, lots |
Definitely not white underneath, else I might have considered
Xanthoria. Could it be
C. decipiens? Or any of dozens of others not described in
Brodo?
Xanthoparmelia weberi?
| | GEN | | foliose lichen, on wood (weathered dead bare juniper) |
| | THAL | | yell-green, shiny, black marg, smooth, KC+ yell, K-, C-, brown bel w rhiz, closely att, wrinkled/bunched in the center, covered w globular unbr isidia |
Definitely
isidia not soredia (too large, smooth, corticate). Doesn't key out on wood. On rock I come up with
X. weberi, which mentions that it rarely is found on wood... but it is not supposed to make it into Utah.
Psora decipiens
| | GEN | | squamulose lichen, on soil |
| | THAL | | round disks, wh tom bel, orange-brown ab, shiny smooth, wh ragged marg, marg sl upturned, 1-1.5mm |
| | APO | | marginal, hemispherical black mounds, somewhat rough |
Placidium lacinulatum?
| | GEN | | squamulose lichen, on soil |
| | THAL | | irreg patches to 5mm, bumpy to lobed, dk green when wet to brown when dry, largish black dots (perithecia?), lt brown bel (hard to clean soil off to see), few rhiz |
Collema crispum?
| | GEN | | squamulose jelly lichen, on soil |
| | THAL | | crisped, erect, no cortex, blackish greenish, upright curved lobules, thickened margin |
Mostly just a guess, as I can
never find apothecia on these darned things.
Psora tuckermanii
| | GEN | | squamulose lichen, on soil |
| | THAL | | 3mm+, irreg, convex, wh marg disappearing almost entirely w age, fissured, green when wet brown when dry, smooth |
| | APO | | red brown, granular, mounts, laminal |
Candelariella terrigena
| | GEN | | crust lichen, on moss |
| | THAL | | v min lobed to areolate, bright yell, bumpy, min rough, K-, C-, KC-, no rhiz bel, sl white just under edge but cannot separate thallus from substrate |
| | APO | | lecanorine, irreg, sl browner disk, no pruina, marg discontinuous |
Would like spores to verify: slightly incorrect range.
Fulgensia desertorum
| | GEN | | crust lichen, on soil |
| | THAL | | sulfur yellow, squamulose, white pruina conspic in parts, convex, v closely att, K+ wine red |
| | APO | | brownish red-orange, min rough but not pruinose |
Again, would like spores to verify.
Rhizoplaca melanophthalma
| | GEN | | umbilicate lichen, on rock |
| | THAL | | v crumpled and bunched, mounded, lt yellish grey-green, smooth, brown smooth bel (except for two wh cracks created by prying the darned thing off the rock) |
| | APO | | wavy, packed, tiny to large, green, pruinose |
Rhizoplaca chrysoleuca
Rhizoplaca subdiscrepans
| | GEN | | foliose lichen, on rock |
| | THAL | | lt green, v areolate to wrinkled-bumpy, smooth, brown bel, varying from umbilicate (and easy to pry off) to broadly attached (and bloody impossible to remove) |
| | APO | | pruinose, lt orange, raised ragged marg, lecanorine, packed, wavy, tiny to huge |
My sample is somewhat intermediate, though perhaps closer to
R. chrysoleuca. It bears mentioning that this sample was only a piece of a larger mass, proving that it is
not umbilicate.
Dermatocarpon miniatum
| | GEN | | umbilicate lichen, on rock |
| | THAL | | grey, thin, pruinose, black fots, large lobes, purple-brown bel, rounded bumpy but not rough bel |
Glypholecia scabra
| | GEN | | umbilicate lichen, on rock |
| | THAL | | broad, shallowly lobed, round, flat to undulating, areolate, smooth, brown and sl to v wh pruinose w white cracks |
| | APO | | cryptolecanorine, broken up w sterile tissue, dk brown |
Physcia dubia
| | GEN | | foliose lichen, on bark |
| | THAL | | lt grey, wh pruinose at tips, wh maculae/pseudocyphellae inside, v few black dots, convex, v narr lobes fanning out at tips, soralia discont (lip-shaped) all along margins, white to pale tan bel, pale rhiz bel, K+ yell, C- |
| | APO | | rare, black, lecanorine, irreg, v wh pruinose, grey ragged marg |
Xanthoria montana
| | GEN | | foliose lichen, on bark |
| | THAL | | bright yell-orange, wh bel, sp wh rhiz, K+ wine red, dk orange pycnidia, finely lobed, loose and spidery |
| | APO | | lots, lecanorine, orange w yellower marg, some wh rhiz bel, flat and round, v finely ggranular, raised thin marg |
?
| | GEN | | foliose lichen, on bark |
| | THAL | | brown to grey, narr convex lobes, smooth, no pruina, conspic black-rimmed pycnidia(?), edges disintigrate into black fine granules, short white bristly cilia, black w black rhiz bel (except wh to brown at edge), K-, C-, KC- |
| | MED | | white, v thin, K-, C- |
