Ochropsoraceae (Arthur) Aime & McTaggart, fam. & stat. nov.

MycoBank number: MB 836640; Index Fungorum number: IF 836640; Facesoffungi number: FoF;

Basionym: Ochropsoratae Arthur, Rés. Sci. Congr. Int. Bot. Vienne: 336. 1906.

Type genus: Ochropsora Dietel, Ber. Dtsch. Bot. Ges. 13: 401. 1895.

Description: Spermogonia Group VI (type 7). Aecia aecidium-type; uredinia malupa-type; aecial states systemic overwintering as mycelium; telia forming crusts, 1-cell deep, at first subepidermal, then erumpent; teliospores germinate without dormancy, either internally (Ochropsora) or externally (Aplopsora). Species likely macrocyclic and heteroecious, although gametothallus not known for Aplopsora.

Included genera:   Aplopsora,   Ochropsora;   likely   includes Ceraceopsora.

Host families: Ranunculaceae (0-I); Rosaceae, Cornaceae (II-III)

Notes: A monophyletic Ochropsoraceae as the earliest diverging lineage of Raveneliineae was recovered in all of our analyses. Aplopsora and Ochropsora were previously treated within the artificial Chaconiaceae (Cummins & Hiratsuka 2003) where they shared the convergent character of teliospore germination without dormancy.
