description: Bensingtonia pseudorectispora Q.M. Wang, F.Y. Bai & A.H. Li sp. nov. MycoBank MB828802. Fig. 14E.   
 Etymology: the specific epithet pseudorectispora refers to the similar colony morphology to that of Bensingtonia rectispora.   
 Culture characteristics: In YM broth, after 7 d at 17 °C, cells are ellipsoidal and cylindrical, 2.8 –3.2 × 7.2 –10.3 μm and single, budding is polar (Fig. 14E), a sediment is present. After 1 mo at 17 °C, a ring and a sediment are present. On YM agar, after 1 mo at 17 °C, the streak culture is pink red, 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, maltose, melezitose, D-mannitol and salicin are assimilated as sole carbon sources. Galactose, Lsorbose, sucrose, cellobiose, trehalose, lactose, melibiose, raffinose, inulin, soluble starch, D-xylose, L-arabinose, D-arabinose, D-ribose, L-rhamnose, D-glucosamine, N-Acetyl-D-glucosamine, methanol, ethanol, glycerol, erythritol, ribitol, galactitol, D-glucitol, Methyl-α- D-glucoside, DL-lactate, succinate, citrate, myo-inositol and hexadecane are not assimilated. Ammonium sulfate, potassium nitrate, L-lysine, ethylamine hydrochloride and cadaverine dihydrochloride are assimilated as sole nitrogen sources. Sodium nitrite is not assimilated. Maximum growth temperature is 22– 23 °C. Growth in vitamin-free medium 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, Be. pseudorectispora differs from its closely related species Be. rectispora in its inability to assimilate sucrose, trehalose and glycerol and its ability to assimilate salicin and ethylamine (Table S1.18).   
 Typus: China, Bomi, Tibet, obtained from a leaf of an unidentified plant, Sep. 2014, Q.-M. Wang (holotype CGMCC 2.5677 T preserved in a metabolically inactive state, ex-type CBS 15750 = XZ154D5).
