Who: Daniel B. Wheeler (Tuberale)

No specimen available

Another lichen found on a sandy slope of a semi-stabilized sand dune. This was found near a road cut with lots of tree canopy over it. It caught my eye because 1) it is quite tall for a lichen and 2) these curious reddish/buff multiple fruiting structures on a multi-branches stalk. The one I’m holding in my hand has at least 12 of these curious fruiting structures on them, which often form a 3- or 4-lobed kind of flower, each lobe its own small cup. The base of the lichen is once again rather nondescript grayish-greeen, without a noticeable black reverse, and rather upright growing, finely wrinkled or crenulate, the base is so small and so overgrown by fruiting structures that they are difficult to see.

Used references: Provisional keys to Ways of Enlichenment: This is a tough one. It’s too tall to be C. cariosa, that seems pretty clear. It could be C. rei if it were sorediate (powdery), but Brodo claims it doesn’t occur in Oregon (and that it is an inland species). This brown-fruited form of C. gracilis is fairly common, so it seems the best guess.
