Buttonwood, lichens.
Lichens on bark of live mahogany out in open in front of F bldg. Half covered below to 100% covered 10-15' up. Quite a tremendous diversity present on this one tree.
orange-pimpled-leprose []
| | GEN | | crust lichen, on live mahogany bark |
| | THAL | | leprose, coarse orange-yellow soredia all over, K+ deep wine-red, orange pimples of pycnidia raised through and above soredia, pycnidia orange top with clear mass of vast numbers of conidia |
| | SPORE | | conidia 1um or so, oblong pips |
Keys very reliably to
Caloplaca citrina no matter how I do it, given the absence of apothecia, but this is well out of range, and on the wrong substrate.
Amandinea "grey green leprose" []
| | GEN | | crust lichen, on live mahogany bark, in crook where water pools |
| | THAL | | leprose, med grey-green, some solid smooth remnants esp near and around apo |
| | APO | | biatorine?, black, 0.5mm, convex, thin raised margin, hypothecium colorless, epihymenium dk brown |
| | SPORE | | 8 per ascus, ellip-football, grey to brown, smooth, 2 cell, distinct thin septum, cells with round bubbles in center sorta toward septum smaller than cells, def not halonate |
| | PARA | | unbr, sl expanded dker at v tips |
Keys clearly to either
Buellia or
Amandinea; the pigmented paraphyses tips makes it the latter.
Brodo only presents two of the 6 N Amer species in this genus.
Dirinaria picta []
| | GEN | | foliose lichen, on live mahogany bark |
| | THAL | | yellish lt green, lobes flat and tiny and overlapping, sl finely white pruinose at tips, piles of fine granular soredia in spots throughout, K+ yell, C- |
| | MED | | white, thin, K- (dissolves almost immediately!), C-, KC- |
Wait! This is probably
Dirinaria picta (not
Pyxine eschweileri): I didn't make explicit note of it, but I bet it doesn't have rhizines
the thin white medulla melted immediately in KOH exposing the black lower cortex, a classic case of
D. if I've seen one.

Graphina "white 8 spore" []
