On the bark of a linden tree, along with patches of Graphis scripta. Photobiont is Trentepohlia - this very humid valley is rich with pure patches of Trentepohlia. The small piece of loose bark I found had no apothecia, but did have two pycnidia. Conidia were hyaline, bacilliform, about 4-5 microns long and 1.2 microns wide.
