MycoBank: MB 822000

Type: — USA. California: Armstrong’s Station, El Dorado Co., alt. 1615 m, on Sanicula graveolens (as S. nevadensis ), 11 Jun 1895, G. Hansen ( BPI 175301, holotype, designated here).

Sori in leaves, forming round or elongate to polyangular, amphigenous, flat, scattered or sometimes gregarious, initially white, later pale yellowish-brown spots, 1–10 mm diameter or larger when confluent. Spores confluent, sometimes in chains, globose, subglobose, ovoid, ellipsoidal to slightly irregular, (11) 12–16 × 14–20 (22) μm diameter [av. ± SD, 14.9 ± 1.8 × 16.7 ± 2.9 μm] with subhyaline content. Spore wall 2–6 μm thick, uneven, hyaline to subhyaline, smooth. Anamorph absent.
