I wouldn’t worry about the color so much

The difference in color between sun and shade specimens can be enormous. If I remember right, according to Brodo there are very few (if any) other sterile crustose lichens covered with long fine isidia. That observation should trump color.

Very similar to Loxosporopsis corallifera

But the wrong color as noted in Brodo. Maybe because the specimen I observed was on the trunk of a Douglas fir away from the sun, but open to the highway. Seems to be more gray-white than yellowish-white, but at that small size, options are limited.

…never seen one, but there’s a striking photo of it in Brodo.
