Description: | CYA, 25°C, 7 days: colony diameters 59-64 mm, entire, floccose; mycelium white, pale-pale yellow (2A2-3), pinkish to pale red (7A2-3); gymnothecia produced; conidiogenesis sparse; exudate tiny droplets, yellowish white (1A2); soluble pigment greyish orange (5B5-6); re-verse brownish roange (6C4-6) to greyish orange (5B4-6). MEA, 25°C, 7 days: colony diameters 65-70 mm, plane, floccose; mycelium white overlaid with yellowish white gymnothecia (1A2); gymnothecia abundant, discrete or confluent; conidiogenesis light; exudates light yellow to yellow (2A5-6); soluble pigment pastel yel-low-yellow (2A4-6); reverse light yellow-yellow (3A5-7). G25N, 25°C, 7 days: no growth. CYA, 5°C, 7 days: no germination. CYA, 37°C, 7 days: colony diameters 62-65 mm, entire, floccose; mycelium white, yellowish white to pastel yellow (1A2-4); conidiogenesis sparse; exudates tiny droplets, yellowish white to pale yellow (1A2-3); soluble pigment greyish orange (5B4-5); reverse brown orange (7C4-6), greyish orange (5B3-5); light brown (6D4-6) or brown (7E5-6). Gymnothecia on MEA globose, pastel yellow to yellow (3A4-6), maturing in 11-14 days, abundant, confluent or discrete, mostly superficial, less often embedded in the mycelium, 144-384 μm, with peridium composed of tightly interwoven hyphae; ascomatal initials long cylindroidal cells with apical fist-shaped, tight coil, in turn develop into ascogenous hyphae; asci subglobose, borne in chains, 7.1-8.3 × 6.3-7.1 μm, uncolored; ascospores ellipsoidal to flattened ellipsoidal with a single equatorial flange, smooth, 4.0-4.8 × 2.4-3.2 μm, uncolored. Conidiophores and conidia: conidiophores and stipes on MEA or CYA unusually monophi-alidic structures, not the typical biverticillate or monoverticillate penicilli described by Pitt (1979); phialides elongate, cylindroidal, gradually tapering, 7.9-30.0 × 1.6-2.8 μm, smooth; conidia ellipsoidal, obovate, uncolored, 3.6-7.1 × 2.7-4.2 μm, smooth, thin walled, borne in a short, single chain. | |||
