Observation 12953: Candelariella efflorescens R.C. Harris & W.R. Buck

Crustose lichen, on oak bark with Physcia adscendens and Xanthoria fulva.
THALLUS: yellow granules with a few minute yellow corticate lobes, K- to slightly reddish
APOTHECIA: minute, 0.19-0.22 mm (N=3), lecanorine, paraphyses cylindrical and not at all swollen
SPORES: how many per ascus?, (11)12+/-0.8(14) x (4.7)5.2+/-0.4(6.0) µm (Q=(2.0)2.4+/-0.3(2.8)) (N=8), simple, hyaline, one end typically narrower than the other, smooth

According to the flora, no fertile specimens of Candelariella efflorescens have been seen in this area, making me wonder if this is the correct ID. Not sure what else it can be, though…
