crustose?

    Hi all,


    In the photo gallery are some pictures of a lichen (LABE-335) from Northern California on basalt. The thallus is 1+mm thick (so it could be considered squamulose). Cortex and medulla are K=Y slow to orange, KC+O, C-, I-, P+Y and UV-. Spores are egg shaped and range from 17.92-25.6 X 12.8-17.92. The K+ yellow turning orange made me think this is a Lecidea, but it doesn't seem to fit.


    Anyone have any ideas?


    Thanks,

    Steve

    Hi Steve. You should try the soil crust book, key G.
