Collection number: Jason Dart 991

Notes:
On sandstone boulder used in rock rip-rap beneath the railroad bridge over Graves Creek, near the Salinas River.

Thallus scant, tan, becoming areolate and greenish orange, maybe tending toward subsquamulose. Apothecia crowded, plane to slightly flexuous, often angular due to constriction by adjacen apothecia. Disk light orange, usually but not always thickly pruinose, matte. Hypothecium composed of linear hyphae (prosoplectenchymatous).

Spores constricted at septum before heating. After heat septum really short: Average spore size 15.8×7.4µm with isthmus 2.2µm (n=9).
