Kwoniella ovata Q.M. Wang, F.Y. Bai & A.H. Li View in CoL sp. nov. MycoBank MB828747. Fig. 7M View Fig .
Etymology: the specific epithet ovata refers to the ovoid cell morphology of the type strain.
Culture characteristics: In YM broth, after 7 d at 17 °C, cells are ovoid and ellipsoidal, 4.2– 6.8 × 5.2– 7.9 μm and single, budding is polar ( Fig. 7M View Fig ), a sediment is formed. After 1 mo at 17 °C, a ring and sediment are present. On YM agar, after 1 mo at 17 °C, the streak culture is tannish-white, butyrous, smooth and glossy. The margin is entire. In Dalmau plate culture on corn meal agar, pseudohyphae are not formed. Sexual structures are not observed on YM, PDA, V8 and CM agar. Ballistoconidia are not produced.
Physiological and biochemical characteristics: Glucose fermentation is absent. Glucose, galactose, sucrose, maltose, cellobiose, trehalose, lactose, raffinose, melezitose, soluble starch, Dxylose, L-arabinose, D-arabinose, D-ribose, L-rhamnose, ethanol, glycerol, ribitol (delayed and weak), galactitol, Dmannitol, D-glucitol, Methyl-α- D-glucoside (weak), succinate and myo-inositol (weak) are assimilated as sole carbon sources. Lsorbose, melibiose, inulin, D-glucosamine, methanol, erythritol, salicin, DL-lactate, citrate and hexadecane are not assimilated. Ammonium sulfate, sodium nitrite and L-lysine (weak) are assimilated as sole nitrogen sources. Potassium nitrate, ethylamine hydrochloride and cadaverine dihydrochloride are not assimilated. Maximum growth temperature is 37 °C. Growth in vitamin-free medium is negative. Starch-like substances are not produced. Growth on 50 % (w/w) glucose-yeast extract agar is negative. Urease activity is positive. Diazonium Blue B reaction is positive.
Physiologically, Kwon. ovata differs from its closely related species Kwon. pini and Kwon. dejecticola in its ability to grow at 37 °C ( Table S1.6 View Table 1 ).
Typus: China, Hebei province, obtained from a leaf of an unidentified plant, Nov. 2006, Q.-M. Wang (holotype CGMCC 2.3439 T preserved in a metabolically inactive state, ex-type CBS 15475 = H1C1).
