Posting some photos for identification. Keys to Lecidea (Didn’t check ascus type with iodine.) Thought might be L. lapicida except the medulla is negative for both K and Iodine. (Yellow bleeds off apo sxn with K.) Apothecia ≤ 1mm, spores average 10x5µm. On Si rock, 3,600’, near Snoqualmie Pass, WA. Want to know because its quite abundant and also because I like it.
