Nomenclature: Current taxonomic status: accepted. Taxonomic rank: variety. Synonyms: Microsphaera caprifoliacearum var. flexuosa (U. Braun) U. Braun; Erysiphaceae Tul. & C. Tul.; Erysiphales.

Type Information: Basionym: Microsphaera lonicera var. flexuosa U. Braun. Type: Microsphaera lonicera var. flexuosa U. Braun.

Taxonomic Literature: Taxonomic notes: This variety differs from var. lonicera by ascomata characters, see below. Braun U., Beih. Nova Hedwigia 89: 1-700 [431-433] (1987).

Biogeography: Northern hemispheric. Continent: Northern America (USA, Canada, widespread). Country or state(s): Washington (USA).

Ecology: Biotroph; phytopathogenic; growing on leaves, epiphyllous (mostly) or amphigenous. Host or Phorophyte Taxonomy: Lonicera ciliosa (Pursh.) Poir.; Lonicera, Caprifoliaceae.

Reproduction Strategy: With sexual (and possible asexual) stages. Ascocarps: Cleistothecioid, orbicular, forming independently from the host thallus or mycelium, .065-.12 mm in diam.. Margin: External filaments present; recurved (when fully mature) or straight, 1.5-3.5-(4) µm long, few, 4-15 per mm², growing between the lower and upper hald of the ascocarp, flexuose, ramified, dichotomously branched (3-6 times, closely and regularly).

Asci: 3-10 asci per ascocarp, not stipitate or indistinctly stipitate, 40-60 µm long, 25-40 µm wide; dehiscence unitunicate.

Ascospores: c. 4 per ascus, spores 4-5 per ascus, subglobose, ellipsoid, or ovoid, 15-24 µm long, 8-14 µm wide; septa absent.

Conidium Formation: Conidiogenous cells single. Conidia: Ellipsoid or doliiform; macroconidial, 25-40 µm long, 14-22 µm wide.
