　Description： Colony diameters on Czapek’s agar larger than 9 cm in 2 weeks at 25°C, floccose; mycelium white to pale ivory yellow (R., Plate XXX), reverse capucine buff, light salmon-orange or seashell pink to flesh color (R., Plate XXXII, XIV). At the 37°C texture as 25°C, but conidial heads radiate to short columnar, deep malachite green to french green (R., Plate XXXII); reverse capucine buff to pale orange-yellow (R., Plate III). Colony diameters on Malt Extract Agar 7.0-7.5 cm in 2 weeks at 25°C, floccose; mycelium white; conidial heads inconspicuous, radiate, light hellebore green (R., Plate XVII); cleisto-thecia abundant, scattered, ivory yellow to cartridge buff (R., Plate XXX); reverse cartridge buff to cream-buff (R., Plate XXX). Colonies textures at 37℃ same as 25°C, but mycelium and Cleistothecia ivory yellow to cream-buff (R., Plate XXX), reverse cream-buff to honey yellow (R., Plate XXX). Cleistothecia 174.0-365.0 μm, globose to subglobose, asci globose to ellipsoidal, 8-spored, 10.7-12.7 μm in diameter, ascospores lenticular to subglobose, spore bodies 4.6-6.5 × 4.0-5.6 μm; with two equatorial flanges 1.5-2.8 μm wide; convex surface spinose to spinulose. Colony diameters on Czapek’s Agar with 20％ added sucrose larger than 9 cm in 2 weeks at 25°C, floccose; mycelium white; reverse light buff, pale orange to capucine buff (R., Plate XV, III). At 37°C the colony texture the same as 25°C, but with abundant conidial heads along the margin, radiate to columnar, diamine green or dark sulphate green to dark zinc green (R., Plate VII, XIX); reverse light buff (R., Plate XV). Stipes smooth, 38.0-950.0 × 2.2-8.0 μm; aspergilla uniseriate; vesicles clavate to globose 4.0-18.0 μm wide; phialides covering 1/2 to 3/5 of the vesicle, 5.4-11.7 × 2.0-3.2 μm; conidia globose, ellipsoidal, smooth to finely roughened, 2.7-4.4 × 2.4-4.0 μm. Colony diameters on M40Y larger than 9 cm in 2 weeks at 25°C, floccose; Mycelium white to pale yellow; conidial heads abundant, radiate to loosely columnar, light hellebore green (R., Plate XVII); reverse cream color (R., Plate XVI). At 37°C, colony texture the same as at 25℃, but producing abundant conidial heads, conidial heads radiate to loosely columnar, light hellebore green to bice green (R., Plate XVII), reverse cream color (R., Plate XVI).

　Note： On Czapek’s agar with 20％ added sucrose at 37°C, conidia globose, subglobose, ellipsoidal, smooth to finely roughened. Mycelium and cleistothecia on Malt Extract Agar at 37°C, yellow to cream-buff. Ascospores subglobose, with two equatorial flanges, and convex surface spinose to spinulose. N. fischeri var. spinosa has larger asci and ascospores convex surfaces spinose to spinulose under SEM, which differs greatly from N. fischeri var. fischeri.
