Data Set Maintenance: Data set compiled and standard item. Data set author(s): Schubert K. @EXCL@ Kainz C. (06-03-21).

Nomenclature: Current taxonomic status: accepted. Taxonomic rank: species. Synonyms: Phyllactinia suffulta f. pistaciae Jacz.; Erysiphaceae Tul. & C. Tul.; Erysiphales.

Type Information: Basionym: Phyllactinia pistaciae H. D. Shin & Y. J. Choi. Type: Phyllactinia pistaciae H. D. Shin & Y. J. Choi.

Taxonomic Literature: Taxonomic notes: + ascomata outer wall-cells irregularly polygonal to somewhat rounded, 10-25 µm wide, not distinct; hyphae substraight to flexuous, sometimes undulate to geniculate, 50-110 × 4-6(-10) µm, mostly branching at right angles, with a septum near the branching point; appressoria well-developed, hook- to rod-shaped, branched or not, wavy or lobed, single or opposite in pairs; penicillate cells crowded on the upperpart of the ascoma, hyaline, feet composed of one to several cells, terminal cell 16-56 × 16-40 µm, filament 12-80 µm long, 3-6 µm wide, but swollen at the apex, reaching up to 10 µm wide. Shin H.D. & Choi Y.J., Mycotaxon 87: 213-221 (2003).

Biogeography: Continent: Asia-Temperate. Country or state(s): Turkmenistan.

Ecology: Biotroph; phytopathogenic; growing on leaves, mostly hypophyllous or amphigenous. Host or Phorophyte Taxonomy: Pistacia vera L.; Pistacia, Anacardiaceae.

Reproduction Strategy: With sexual (and possible asexual) stages. Ascocarps: Cleistothecioid (blackish brown), orbicular (depressed globose), scattered, .22-.28 mm in diam.. Margin: External filaments present; not interlaced, straight (filiform with a bulbous base, 40-55 µm wide at the ball, 7-10 µm wide above the ball and gradually narrower upwards, apex 6-8 µm wide and obtuse), .8-1.2-(1.4) µm long, hyaline, few, 6-13 per mm², growing between the lower and upper hald of the ascocarp, stiff and straight, not ramified, aseptate.

Asci: (14)-18-30 asci per ascocarp, indistinctly stipitate or distinctly stipitate, 60-100 µm long, 25-40 µm wide; dehiscence unitunicate (olivaceous-brown, moderately thick-walled, but thinner at the upper part).

Ascospores: 1–2 per ascus, spores 2 per ascus, oval or cylindrical (-oval), 34-42 µm long, 18-24 µm wide; septa absent; wall pale brown (olivaceous, guttulate).

Conidiomata: Present; hyphomycetous.

Conidiophores: Ovulariopsis-type (conidiophores single on a hyphal cell, arising from the upper part of creeping hyphae, position mostly central, mostly composed of three cells, producing conidia singly, followed by a shorter cell and a foot-cell, spirally twisted or wavy at the basal part or throughout the foot-cells, with a basal septum at 5-25 µm away from the branching point of the mycelium); not branched; conidiophore cells 110-240 µm long, basal cells 5-7 µm wide. Conidium Formation: Conidiogenous cells single. Conidia: Clavate; macroconidial (germ tubes at randomly located sites), not branched, rounded at one end (at the apex or somewhat pointed, non-papillate; conically), 52-72-(80) µm long, 17.5-25 µm wide; aseptate; cell wall hyaline; without distinct fibrosin body fibrosin bodies.
