Grayish microfoliose lichen with large cerebriform apothecia (?). Collected a portion with permit and with on-site supervision by monument biologist.

Apothecia sections show a lightly colored hymenium, spores hyaline, 8/ascus, simple and quite small, about 8-9 microns in length. The apothecia is C plus pink-red, rather transient, likely gyrophoric acid. K negative. Numerous pycnidia present.

White Aspicilia-like lichen with tiny areoles. Collected a portion with permit and with on-site supervision by monument biologist.

Rimose white crust with 1-mm thallus units, sunken black apothecia, lecanorine margin, 4-8 spores per ascus (mostly 4), brown, muriform, measuring 30-32 x 16-17 microns. Thallus K negative (both under dissecting scope and in sections under compound scope) and C plus red.

Whitish crust on strongly HCL-reactive boulder, collected with permit for UCD.

Thallus consisting of thick 1-mm pruinose areoles with immersed lecanorine apothecia, deeply fissured. The epihymenium is brown and the overall hymenium measures approximately 115 microns in thickness. The thallus has numerous pycnidia with roundish 2-micron conidia and is K, KC and C negative via spot tests performed on sections under the compound scope. Apothecia slices placed in Lugol's and squashed stain red, so apparently hemiamyloid.
