description: Pseudobensingtonia fusiformis Q.M. Wang, F.Y. Bai & A.H. Li sp. nov. MycoBank MB828803. Fig. 14F.   
 Etymology: the specific epithet fusiformis refers to the fusiform vegetative cells of the type strain.   
 Culture characteristics: In YM broth, after 7 d at 17 °C, cells are cylindrical, ellipsoidal and fusiform, 7.6– 13.3 × 2.2–3.6 μm and single, budding is polar (Fig. 14F), a sediment is present. On YM agar, after 1 mo at 17 °C, the streak culture is yellow, butyrous, wrinkled and dull. 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, L-sorbose, sucrose, cellobiose, trehalose, lactose, raffinose, inulin, D-xylose, L-arabinose (variable), D-ribose (weak), ethanol (variable), glycerol, erythritol, ribitol, D-mannitol, D-glucitol, D-gluconate and succinate are assimilated as sole carbon sources. Galactose, maltose, melibiose, melezitose, soluble starch, D-arabinose, Lrhamnose, D-glucosamine, N-Acetyl-D-glucosamine, methanol, galactitol, Methyl-α- D-glucoside, salicin, DL-lactate, citrate, myo-inositol and hexadecane are not assimilated. Ammonium sulfate, L-lysine, ethylamine hydrochloride and cadaverine dihydrochloride are assimilated as sole nitrogen sources. Potassium nitrate and sodium nitrite are not assimilated. Maximum growth temperature is 23 °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, Ps. fusiformis differs from its closely related species Ps. ingoldii and Ps. musae in its inability to assimilate citrate and its ability to assimilate inulin (Table S1.19).   
 Typus: China, Bomi, Tibet, obtained from a leaf of an unidentified plant, Sep. 2014, Q.-M. Wang (holotype CGMCC 2.5823 T preserved in a metabolically inactive state, ex-type CBS 15647 = XZ152EA3).
