 Etymology: the specific epithet sterigmata refers to the vegetative cells producing conidia on stalk-like conidiophores in the type strain.   
 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. 14M), a sediment is present. One or more conidia are produced on each stalk-like conidiophore. Conidiophore is single or multiple, usually multifurcate. 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 deep 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 allantoid or reniform, 2.6– 3.2 × 3.8– 5.8 μm (Fig. 14N).   
 Physiological and biochemical characteristics: Glucose fermentation is absent. Glucose, galactose, sucrose, maltose (delayed and weak), cellobiose, trehalose, melezitose and inulin are assimilated as sole carbon sources. L-sorbose, lactose, melibiose, raffinose, 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-mannitol, D-glucitol, Methyl-α- D-glucoside, salicin, DL-lactate, succinate, 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.   
 Typus: China, Fanjingshan Mountain, Guizhou province, obtained from a leaf of an unidentified plant, Oct. 2011, Q.-M. Wang (holotype CGMCC 2.4539 T preserved in a metabolically inactive state, ex-type CBS 15553 = FJS3F22).
