    Hi people,

    while seeking for some fungi specimens, I came across some orange lichens
    on a rock; I think they're of Xanthoria group, but I couldn't find out more
    than this.
    Any more detailed identification and information welcomed.

    I'm leaning toward Caloplaca flavovirescens, or sulphur-firedot lichen. If you can get your hands on the Brodo+Sharnoffs' Lichens of North America book, compare your photograph against the one in the book.

    Nice crust. I think it is a Caloplaca sp., a close relative of Xanthoria.

    thank you for your identification's efforts.
    I've seen that there's quite much agarologic activity around
    these lichens, so my question now is, do anyone know
    if they feed from lichens or is there a symbiosis involved?

    Thank you for help

    Hmm. Very curious, I've never read of anything along those lines before (if by agarologic activity, you mean the mites seeming to cluster around the lichens).
