Observation 102513: Physconia perisidiosa (Erichsen) Moberg
When: 2012-07-20
(34.2177° -118.1304° 957m)
No herbarium specimen

Notes: HABITAT recently lightly-burned open oak forest high on north slope; SUBSTRATE bark of Quercus chrysolepis at chest height; ASPECT partly shaded; NOTES reflexed lobe tips with very coarse non-isidioid soredia under tips and margins, white and ecorticate? below with black squarrose rhizines, particularly pruinose.

There were a couple of oaks that survived the Station Fire, all covered with Physconia. I took a small sampling from all over, and was surprised to find that it was all P. perisidiosa, with only a tiny bit of P. enteroxantha mixed in on one piece.
