Endolithic crust growing on HCL-negative rock, collected a portion with permit for UCD. Lecideine apothecia are 0.5-1.0 mm in diameter with upturned gray edges, chemical tests on apothecia sections in water are all negative (K, C and P), hymenium is hyaline and about 80 microns in thickness, no polarizable crystals were seen. Hypothecium brown. Spores are narrowly ellipsoid, simple, hyaline, 8/ascus and about 10 microns in length and 2.5-4.0 microns in width. Iodine does not appear to stain exciple.
