| Scientific Name | Ann. Mycol. 1: 329. 1903. |
|---|---|
| Synonyms | Phragmidium ivesiae subsp. wyomingense R.S. Peterson, Mycologia 54: 389. 1963 [1962]. |
| Disease | Rust fungus on Potentilla and Ivesia species (Rosaceae) |
| Taxonomic Rank | |||
|---|---|---|---|
| Order | Pucciniales | Family | Phragmidiaceae |
| Distribution | North America (Arthur 1934; Conners 1967; Peterson 1967; Savile 1976; Tykhonenko 2007). |
|---|---|
| Characteristics | Autoecious macrocyclic rust fungus. Spermogonia and aecia rarely observed; spermogonia adaxial, subcuticular, flat hymenia. Aecia subepidermal, Caeoma-type, erumpent with sparse paraphyses; aeciospores subglobose to ellipsoid, 20–27 × 16–22 µm, echinulate. Uredinia on abaxial leaf surface, Uredo-type, orange-yellow, surrounded by paraphyses; urediniospores 20–28 × 16–22 µm, pale yellowish, echinulate. Telia dark brown to black, producing (2–)3(–4)-celled teliospores 35–55 × 19–28 µm, bilaminate wall with cinnamon-brown inner layer and colorless outer layer, sparse warts; pedicels up to 100 µm long. |
| Notes | Occurs on numerous Potentilla and Ivesia species across North America. Spermogonia and aecia infrequently observed. Uredinial and telial morphology closely related to Phragmidium section on Potentilla, but distinguished by teliospore wall layering and host specificity. |
| Economic importance | Minor rust pathogen on Potentilla and related genera; mainly of taxonomic interest, not economically significant. |
