Begerowomyces foliicola Q.M. Wang, F.Y. Bai & A.H. Li sp. nov.

MycoBank number: MB 828828; Index Fungorum number: IF 828828; Facesoffungi number: FoF; Figs 11F and 15P.

Etymology: the specific epithet foliicola refers to the type strain isolated from a leaf.

Culture characteristics: In YM broth, after 7 d at 17 °C, cells are ovoid and ellipsoidal, 2.6 – 3.9 × 2.7 – 6.0 μm and single, budding is polar (Fig. 15P), a sediment is formed. After 1 mo at 17 °C, a pellicle and sediment are present. On YM agar, after 1 mo at 17 °C, the streak culture is yellowish cream, butyrous, wrinkled and smooth. 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 (delayed and weak), sucrose (delayed), maltose (delayed and weak), cellobiose (delayed and weak), trehalose (delayed and weak), melezitose, inulin (delayed and weak), D-xylose, L-arabinose (delayed and weak), ethanol, erythritol (delayed), ribitol, galactitol, D- mannitol (delayed), D-glucitol (delayed) and succinate (delayed) are assimilated as sole carbon sources. L-sorbose, lactose, melibiose, raffinose, soluble starch, D-arabinose, D-ribose, L- rhamnose, D-glucosamine, N-Acetyl-D-glucosamine, methanol, glycerol, Methyl-α-D-glucoside, 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 26–27 °C. Growth in vitamin-free medium is positive. 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.

Typus: Germany, obtained from a leaf of an unidentified plant, Sep. 2005 (holotype CGMCC 2.3164^T preserved in a metabolically inactive state, ex-type CBS 15655 = G7.4).
