Morphological description: On MEA, mycelium consisting of septate, branched, smooth, hyaline to pale brown, 1\u20134 \u03bcm diam hyphae. Conidiophores differentiated, branched often verticillate, hyaline, pale brown to brown. Conidiogenous cells phialidic, solitary or grouped, terminal, hyaline to pale brown, cylindrical to lageniform, straight or curved, 7\u201330 \u00d7 1.5\u20134 \u03bcm, with a cylindrical to conical, refractive, collarette up to 3.5 \u03bcm long, 1\u20131.7 \u03bcm wide. Conidia lunate, allantoid, hyaline, 4\u201310 \u00d7 1\u20132 \u03bcm. Hyphopodia not observed (Hern\u00e1ndez-Restrepo et al<\/em>. 2016).<\/span><\/p>\n

Culture characteristics: After 7 d at 25 \u00b0C: On PDA reaching 60 mm diam, aerial mycelium scarce to moderate, cottony, olivaceous grey, buff or isabelline, submerged mycelium darker, margin diffuse to rhizoid; reverse centre olivaceous grey, colourless to the periphery. On MEA reaching 62 mm diam, aerial mycelium abundant to moderate, cottony, pale olivaceous grey, darker to the periphery, submerged mycelium dark, margin effuse, rhizoid; reverse fuscous dark, rhizoid to the periphery. On OA reaching 62 mm diam, flat to cottony, greenish grey to grey olivaceous in the centre, white to colourless to the periphery, aerial mycelium moderate to abundant, white, submerged mycelium dark in the centre, margin effuse; reverse pale mouse grey (Hern\u00e1ndez-Restrepo et al<\/em>. 2016).<\/span><\/p>\n
