Specimen available

Another calicioid… but not a lichen this time. (But it’s often treated by lichenologists because of its close affinity to a number of truly lichenized genera in the Mycocaliciales, so it’s still “tainted”. :)

Minute stalked black ascomata (less than 1 mm tall and very slender), growing on bark of dead twigs of Populus trichocarpa.
