Chrysozyma sorbariae Q.M. Wang, F.Y. Bai & A.H. Li View in CoL sp. nov. MycoBank MB828855. Fig. 19C, D View Fig .

Etymology: the specific epithet sorbariae refers to Sorbaria , the plant genus from which the type strain was isolated.

Culture characteristics: In YM broth, after 7 d at 17 °C, cells are elongate ellipsoidal and cylindrical, 1.7–2.7 × 5.8–10.4 μm and single, budding is polar ( Fig. 19C View Fig ), a sediment is present. On YM agar, after 1 mo at 17 °C, the streak culture is cream, butyrous, smooth and semi-gloosy. 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 allantoid or falcate, 2.1–2.9 × 6.4–7.9 μm ( Fig. 19D View Fig ).

Physiological and biochemical characteristics: Glucose fermentation is absent. Glucose, sucrose, maltose, trehalose, melezitose, inulin (delayed and weak), D-mannitol and D-glucitol are assimilated as sole carbon sources. Galactose, Lsorbose, cellobiose, lactose, melibiose, raffinose, soluble starch, D-xylose, L-arabinose, D-arabinose, D-ribose, L-rhamnose, D-glucosamine, methanol, ethanol, glycerol, erythritol, ribitol, galactitol, Methyl-α- D-glucoside, salicin, DL-lactate, succinate, citrate, myo-inositol and hexadecane are not assimilated. Ammonium sulfate, potassium nitrate (weak) and sodium nitrite are assimilated as sole nitrogen sources. Llysine, ethylamine hydrochloride and cadaverine dihydrochloride are not assimilated. Maximum growth temperature is 26 –27 Ί C. Growth in vitamin-free medium is variable. 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, Ch. sorbariae differs well from other Chrysozyma species in its assimilation of carbon and nitrogen sources ( Table S1.34 View Table 1 ).

Typus: China, Bomi county, Tibet, obtained from a leaf of Sorbaria arboricola, Sep. 2004 , F.-Y. Bai (holotype CGMCC 2.2768 T preserved in a metabolically inactive state, ex-type CBS 15460 = XZ9D1).
