Green Mt, lichens.
Up the road, then along the Whitehorse Bluffs trail, then left fork to continue along ridge south to a wonderful viewpoint overlooking the Clearwater Valley and, of course, Whitehorse Bluffs. Nice and sunny and warm on the way up, then a lovely snow flurry, turning slick and icy making for an exciting descent at sunset with the varied thrushes serenading us incongruously as we flailed and crashed and careened out of control down the deathly slopes. Good fun since no one got hurt.
red apotheciate brust
| | GEN | | crust lichen, on dead spruce? twig in sheltered forest early on |
green and black crust
| | GEN | | crust lichen, on cedar twig in sheltered forest early on |
big black apotheciate crust
| | GEN | | crust lichen, on doug fir twig, in damp conifer forest by that lake |
| | GEN | | foliose lichen, on alders in wetlands around the lake |
According to Trevor. Such an obscure little scraggly thing, I'd never have even noticed it.
Melanelia septentrionalis [] [voucher]
| | GEN | | foliose lichen, on alders in wetlands around the lake |
| | THAL | | appressed, highly textured, deep brown all over, no cilia |
| | APO | | common, raised cup-like, margin minutely-warty-textured like thallus, deep brown |
Collected this with the
Cetaria sepincola above without realizing it is probably different. With lobes that narrow can only be
M. trabeculata or
M. septentrionalis.
At lookout point. Very exposed windy spot bursting with hair lichens so must get a fair amount of moisture from mist or clouds forming when warm moist air comes up the valley and hits this ridge. Pines and some sort of igneous rock, and surrounding dessicated soil.
Rhizoplaca chrysoleuca-group [] [voucher]
| | GEN | | umbilicate lichen, on igneous rock |
| | THAL | | mounded, clearly attached at single holdfast, not cracked below, apothecia abundant and crowded pink-peach-orangish |
Umbilicaria torrefacta [] [voucher]
| | GEN | | umbilicate lichen, on igneous rock |
| | THAL | | rumpled, dk brown and shiny above with abundant apothecia, pale to med brown bel and plastered with rhizine-like things all over (all of them) |
| | APO | | black, raised, ext gyrose |
Hmmm, description says apothecia are "rathern sunken", but there is absolutely nothing else this could key to the way I'm reading it... Unless I bothered to actually read every couplet of the darned key. This one has tons of minute pinpricks all over (esp near margins), and had I held it up against a light I'd have seen immediately that it's
U. torrefacta, not
U. muehlenbergia.
Umbilicaria polyphylla [] [voucher]
| | GEN | | umbilicate lichen, on igneous rock |
| | THAL | | smooth black above, min roughened black below (solid black throughout including umbilicus), thin and crisped, no apothecia or soredia or isidia anywhere |
| | GEN | | pelt lichen, on soil and dead moss at base of crags |
Are these two species? Nope. Trevor concurs.
