description: Teunia korlaensis Q.M. Wang, F.Y. Bai & A.H. Li sp. nov. MycoBank MB828757. Fig. 7P.   
 Etymology: the specific epithet korlaensis refers to the geographic origin of the type strain, Korla county, Xinjiang.   
 Culture characteristics: In YM broth, after 7 d at 17 °C, cells are subglobosal to globosal, 3.8–5.1 × 4.3–5.9 μm and single,budding is polar (Fig. 7P), a sediment is formed. After 1 mo at 17 °C, a part ring and sediment are present. On YM agar, after 1 mo at 17 °C, the streak culture is cream, butyrous, smooth and semi-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 (weak), melezitose (weak), inulin (weak), D-xylose (weak), L-arabinose (weak), D-ribose (delayed and weak), L-rhamnose (weak), galactitol, D-mannitol and salicin (weak) are assimilated as sole carbon sources. L-sorbose, melibiose, raffinose, soluble starch, D-arabinose, D-glucosamine, N-Acetyl-D-glucosamine, methanol, ethanol, glycerol, ribitol, erythritol, D-glucitol, Methyl-α- D-glucoside, D-gluconate, DL-lactate, succinate, citrate, myo-inositol and hexadecane are not assimilated. Ammonium sulfate, ethylamine hydrochloride (weak) and cadaverine dihydrochloride (weak) are assimilated as sole nitrogen sources. Potassium nitrate, sodium nitrite and Llysine are not assimilated. Maximum growth temperature is 30 °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, Te. korlaensis differs from the closely related species Te. helanensis in its inability to assimilate soluble starch, D-arabinose, L-rhamnose, ethanol, erythritol, D-glucitol, succinate and L-lysine and its ability to assimilate sucrose (Table S1.7).   
 Typus: China, Korla county, Xinjiang province, obtained from soil, Feb. 2008, Q.-M. Wang (holotype CGMCC 2.3835 T preserved in a metabolically inactive state, ex-type CBS 15653 = 141.19).
