description: Heitmania cylindrica Q.M. Wang, F.Y. Bai & A.H. Li sp. nov. MycoBank MB828845. Figs 17E, F and 18F.   
 Etymology: the specific epithet cylindrica refers to the vegetative cell morphology of the type strain.   
 Culture characteristics: In YM broth, after 7 d at 17 °C, cells are elongate cylindrical, 2.5– 3.4 × 9.9– 16.3 μm and single, budding is polar (Fig. 18F), 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 cream, 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, sucrose (delayed and weak), maltose (delayed), trehalose (delayed), melezitose (delayed), ethanol, glycerol, D-mannitol, D-glucitol and succinate are assimilated as sole carbon sources. Galactose, L-sorbose, cellobiose, lactose, melibiose, raffinose, inulin, soluble starch, D-xylose, L-arabinose, D-arabinose, D-ribose, L-rhamnose, D-glucosamine, N-Acetyl-D-glucosamine, methanol, erythritol, ribitol, galactitol, Methyl-α- Dglucoside, salicin, DL-lactate, citrate, myo-inositol and hexadecane are not assimilated. Ammonium sulfate, potassium nitrate (delayed and weak), L-lysine and ethylamine hydrochloride are assimilated as sole nitrogen sources. Sodium nitrite and cadaverine dihydrochloride are not assimilated. Maximum growth temperature is 22– 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, He. cylindrica differs from its closely related species He. tridentata in its ability to assimilate melezitose, glycerol, D-glucitol, succinate and ethylamine (Table S1.31).   
 Typus: China, Milin county, Tibet, obtained from a leaf of an unidentified plant, Sep. 2015, Q.-M. Wang (holotype CGMCC 2.5650 T preserved in a metabolically inactive state, ex-type CBS 15568 = GPS20.2C8).
