Erysiphe plectranthi H. D. Shin & Y. J. La

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. Taxonomic rank: species. Erysiphaceae Tul. & C. Tul.; Erysiphales.

Type Information: Basionym: Erysiphe plectranthi H. D. Shin & Y. J. La. Type: Erysiphe plectranthi H. D. Shin & Y. J. La.

Taxonomic Literature: Taxonomic notes: + ascomata outer wall cells polygonal, 12-20 µm wide, distinct; vegetative hyphae substraight to somewhat wavy, 50-80 × 4-7 µm, branching at right or narrow angle, with a septum near the branching point; appressoria well-developed, moderately lobed to multilobed, single or opposite in pairs. Shin H. D., Erysiphaceae of Korea. 1- [57-59]. Suwon, Korea (2000).

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

Ecology: Biotroph; phytopathogenic; growing on stems, leaves, or inflorescences, mostly epiphyllous or amphigenous. Host or Phorophyte Taxonomy: Plectranthus, Labiatae.

Reproduction Strategy: With sexual (and possible asexual) stages. Ascocarps: Cleistothecioid (blackish brown), orbicular (depressed globose), forming independently from the host thallus or mycelium, scattered (to subscattered), .083-.12 mm in diam.. Margin: External filaments present; interlaced with each other or interwoven with surrounding mycelium, mycelioid, straight, (1)-3-6 µm long, 4.5-6 µm in diameter, hyaline or pigmented (subhyaline, rarely pale brown at the base), numerous, 8-18 per mm², growing all across the lower half of the ascocarp, geniculate (bent) (often undulate to tortuous), smooth, thin, not ramified (occasionally with short outgrowths), septate ((1-)2-3-septate).

Asci: 4-8 asci per ascocarp, not stipitate or indistinctly stipitate, 52-68 µm long, 41-49 µm wide; dehiscence unitunicate (moderately thick-walled, but usually thinner at the upper part).

Ascospores: c. 8 per ascus, spores 6-8 per ascus, ovoid, 22-27 µm long, 12-15 µm wide; septa absent.

Conidiomata: Present; hyphomycetous.

Conidiophores: Pseudoidium-type; not branched (single or two or rarely three on a hyphal cell, arising from the upper part of mother cells, position central to somewhat non-central, simple, straight in foot cells, followed by (2-)3(-4) straight cells, with a basal septum at the branching point of the mycelium); conidiophore cells 100-185 µm long, basal cells 7-9 µm wide. Conidium Formation: Conidiogenous cells single. Conidia: Ovoid or fusiform; macroconidial (producing germ tubes on the shoulder), not branched, 27-40 µm long, 15-19 µm wide; aseptate; without distinct fibrosin body fibrosin bodies.
