    Hello Everyone,


    Query 1: Am I correct in understanding A. setifera is no longer accepted nomenclature for the lichen forms in North America and that A. setifera refers only to those forms in Europe?


    Query 2: Am I correct in understanding the North American form, A. Crinalis, is a separate species?

    This winter I hope to focus on A. crinalis on the south coast of Oregon between Sisters Rocks State Park and Bandon State Natural Area. 


    I have located only two A. crinalis on the south coast. One in Cape Blanco SP and the other in Bandon State Natural Area. I suspect it is in Floras Lake SP, however, I have not located any to date.


    Both specimen were around 3 cm x 2.5 cm with no apothecia. I have experience with A. crinalis along the great lakes shorelines in Michigan's Upper Peninsula. It is curious to me when I located it in Michigan there was never just one individual growing. It was always the case the many individuals were found growing together. Also, apothecia was present on all individuals on a bark substrate. The forms that grew on a rock substrate lacked apothecia. The individuals I located here on the coast are on the bark of Shorepine and lack apothecia. I did not collect these individuals.


    Here is a link to a collection of photos taken of the Cape Blanco SP individual.

    That looks like Heterodermia to me, only because it appears to have soredia on the underside. H. leucomela is uncommon, but A. crinalis is very rare in OR. 


    Good luck hunting!

    Hello John,


    Here is a link to A. crinalis images I captured off the shore of Lake Michigan near St. Ignace, Michigan on April 20th 2010.

    Also, here is a link to image of Heterodermia leucomela I captured in Bandon State Natural Area on September 29th here on the south coast of Oregon.

    It seems to me the overall growth forms of the two lichens differ. For example, A. crinalis is more bushy and the lobes are longer and more branched than H. leucomela.
