Morphological description: On MEA, mycelium consisting of septate, branched, smooth, hyaline to brown, 1\u20134 \u03bcm diam hyphae. Conidiophores more or less differentiated, verticillate. Conidiogenous cells phialidic, hyaline to pale brown, solitary or grouped, terminal, sometimes intercalary, cylindrical, lageniform, 5\u201320 \u00d7 2\u20134.5 \u03bcm, collarette up to 3 \u03bcm long, 1\u20132.5 \u03bcm diam. Conidia lunate, slightly or strongly curved, hyaline, 5\u201311.5 \u00d7 1\u20132 \u03bcm. Hyphopodia lobed, brown, 16.5\u201324 \u00d7 15.5\u201323.5 \u03bcm (Hern\u00e1ndez-Restrepo et al<\/em>. 2016).<\/span><\/p>\n

Culture characteristics: After 7 d at 25 \u00b0C: On PDA reaching 74 mm diam, flat, aerial mycelium scarce, cottony, white, submerged mycelium dark, in the centre hazel, grey, isabelline, olivaceous grey, buff to the periphery, margin effuse, rhizoid; reverse fuscous black, mouse grey or isabelline in the centre, no change to the periphery. On MEA reaching 76 mm diam, aerial mycelium moderate, cottony to funiculose, white, mouse grey to pale mouse grey, submerged mycelium dark (mouse grey), margin effuse, rhizoid; reverse centre fuscous, periphery amber white to white. On OA reaching 77 mm diam, flat, aerial mycelium scarce to moderate or abundant, cottony to funiculose, white, submerged mycelium dark, olivaceous grey, olivaceous black, dark mouse grey, margin effuse, rhizoid; reverse olivaceous, mouse grey, leaden grey, no change to the periphery (Hern\u00e1ndez-Restrepo et al<\/em>. 2016).<\/span><\/p>\n

Specimens examined: Netherlands, near Barendrecht, isolated from Ctenanthe<\/em>, stem base, J.W. Veenbaas-Rijks (holotype, CBSH-22580; culture ex-type, CBS352.93). USA, Florida, isolated from Stenotaphrum secundatum<\/em>, 1988, M. Elliott, CPC26022; 1990, M. Elliott, CPC26025 = CBS141381; 1991, M. Elliott, CPC26036 = CBS141382; Georgia, isolated from Eremochloa ophiuroides<\/em>, 1994, H. Wilkinson, CPC26056 = CBS141383 (Hern\u00e1ndez-Restrepo et al<\/em>. 2016).<\/span><\/p>\n
