Can anyone determine the genus from these photos? The samples are very small, about 1 cm in diameter. Maybe too small? The medulla is K+Y.
Found in the forest near Gifford-Pinchot forest on a conifer twig along side Hypogymina, Bryoria and Usnea.
Looks very much like Platismatia glauca, but if the medulla is K+ then it isn't. Possibly it is a shaded Cetraria platyphylla that looks wierd. Is there a burning reason you have to ID this? If not, I'd say it is too small a specimen.
Not really, I was just feeling stumped by it! I was thinking Cetraria.
Also, thank you! :)
