Location 4
No Name Key, same road as in Location 3, farther on and off-trail in the
scrub to the right. There's a handy little trail that meanders amoong the scrub sort of parallelling the road. The near end is hidden off the first little spur road that goes off to the right, search among the buttonwoods where the road enters the water. Many wonderful Parmotrema and tons of good pyrenolichens and airplants and more. It's all edge-of-hammock scrub: poisonwood, red ironwood, spanish stopper, blolly, black bead, buttonwood, saffron plum, and probably a black mangrove or two. As lichens grow happily on the bark of most of these species, the forest is well-ventilated but shaded enough not to be too exposed to direct sunlight, and it is well-situated to pick up marine aerosols, this makes ideal epiphytic lichen and flower territory.
Coccocarpia erythroxyli [] [voucher]
| | GEN | | foliose lichen, on bare wood of old stump (unknown ID), shaded |
Parmotrema zollingeri [] [voucher]
| | GEN | | foliose lichen, on various bark, shaded |
| | THAL | | ruffled, flat, lobes to 15mm wide, no markings, pycnidia usually present and abundant, black below w almost no rhiz, brown and naked in broad zone near marg |
| | APO | | present in large specimens but always sparse |
10a on blolly, 10b on spanish stopper, 10c on unknown dead limb (stopper?)
Parmotrema "sorediate" [] [voucher]
| | GEN | | foliose lichen, on various bark, shaded |
| | THAL | | ruffled, flat, lobes to 20mm wide, no markings, lt gray to lt greenish to med gray, smooth to wrinkled in age, piles of coarse soredia on wrinkles and raised horn-like wrinkles, black bel except brown on broad zone near marg, almost no rhiz, pycnidia not present |
11a on blolly, 11b on dead limb, 11c on black bead.
| | THAL | | black bel, frosted near lobe tips |
| | THAL | | white bel, not frosted |
| | GEN | | foliose lichen, on blolly and black bead bark, shaded |
| | THAL | | v tightly appressed, flat, lt green, black to brown at tips bel w abundant short black simple rhiz, unmarked, lobes well branched and imbricate and 1-2mm wide |
| | APO | | abundant in center, ~1mm wide, varying quantities of thallin rim from thick and even to thin and black-pimpled as with pycnidia, many lacking the actual disk |
I'm fairly sure this must be
Pyxine despite there being no apothecia that are truly lacking the thalline rim. If not, I haven't a clue what it is.
