Hello everyone,
I have two Cladonia specimens from the Evergreen State College campus leading to some confusion. I am hoping these compilation photos I put together will be large enough to act a visual aids without confusing which specimens I am referring to below. I am using Macrolichens, 2nd ed. to key.
Both specimens lead me to the C. subulata / C. coniocraea / C. ochrochlora section of the key, but then things become muddy. For example, the perforations in Cladonia 1 could be C. subulata though the substrate isn't right and the squamules are quite large. Cladonia 2 also has very large squamules and could be C. ochrochlora but apothecia in this species are rare. They could also both be the same thing. I am curious to know what others think.
Thanks for your time and guidance!
