Podosphaera koreana (H. D. Shin & U. Braun) U. Braun & S. Takam.

Data Set Maintenance: Data set compiled and standard item. Data set author(s): Schubert K. @EXCL@ Kainz C. (06-01-31).

Nomenclature: Current taxonomic status: accepted or basionymous. Taxonomic rank: species. Erysiphaceae Tul. & C. Tul.; Erysiphales.

Type Information: Basionym: Sphaerotheca koreana H. D. Shin & U. Braun. Type: Sphaerotheca koreana H. D. Shin & U. Braun.

Taxonomic Literature: Taxonomic notes: + ascomata outer wall cells irregularly polygonal to rounded, large, 12-52 µm wide, distinct; vegetative hyphae substraight to somewhat wavy, irregular in width, 50-75 × 5-8 µm, branching at narrow or right angle, with a septum near the branching point; appressoria poorly developed, only simply swollen or nipple-shaped, single. Shin H. D., Erysiphaceae of Korea. 1-320 [237-238]. Suwon, Korea (2000).

Biogeography: Continent: Asia-Temperate. Country or state(s): Korea (North & South) (endemic ?).

Ecology: Biotroph; phytopathogenic; growing on stems or leaves, amphigenous. Host or Phorophyte Taxonomy: Corydalis ochotensis Turcz.; Corydalis.

Reproduction Strategy: With sexual (and possible asexual) stages. Ascocarps: Cleistothecioid (dark brown), orbicular (subglobose), forming independently from the host thallus or mycelium, not emerging (partly immersed in the mycelial masses), sub scattered or gregarious, .08-.106 mm in diam.. Margin: External filaments present; mycelioid, straight, .5-2 µm long, 5-8 µm in diameter, hyaline or pigmented (brown at the base and becoming hyaline upwards), few, 3-10 per mm², growing on the upper half of the ascocarp, smooth, thin, not ramified, septate (1-5-septate, with a basal septum at 10-20 µm away from the base).

Asci: 1 asci per ascocarp, 75-94-(140) µm long, 52-64-(80) µm wide; dehiscence unitunicate (moderately thick-walled, but thinner at both ends).

Ascospores: c. 8 per ascus, spores 8 per ascus, ellipsoid, 22-26 µm long, 16-18 µm wide; septa absent; wall sub hyaline (due to dense cytoplasm and minute oil drops).

Conidiomata: Present; hyphomycetous.

Conidiophores: Euoidium-type; not branched (single on a hyphal cell, arising from the upper part of mother cells, position central to non-central, foot cells straight without swollen bases, followed by 2-3 straight cells, foot cells short, with a basal septum at the branching point of mycelium); conidiophore cells 110-160 µm long, basal cells 9-11 µm wide. Conidium Formation: Conidiogenous cells in chains. Conidia: Oval to cylindrical; macroconidial (germ tubes on one side, bifurcate), not branched, crenate, 29-36 µm long, 12-16 µm wide; aseptate; with distintly visible fibrosin body fibrosin bodies.
