0C59BD409B785EF5B4C7943FF5A2B90E.taxon	description	Description. On CMA and PDA hyphae branched, septate, hyaline, smooth, 0.9 – 1.9 μm wide. Coiled hyphae sometimes found on CMA. Hyphae form tight bundles of 3 – 11 hyphae on PDA. Racquet hyphae absent. Fertile hyphae bearing aleurioconidia, sessile or stalked. Arthroconidia not observed. Conidiophores abundant, solitary, usually curved, occasionally erect, arising in acute angles with the main axis, hyaline, smooth, usually bearing verticils of two to four branches arising from the stipe at an acute angle. Conidiophores more abundant on CMA than PDA. Aleurioconidia are pyriform to clavate or obovoid with a broad truncate basal scar, 2.8 – 4.6 × 1.7 – 3.2 μm (av = 3.7 × 2.5 μm, n = 50), in conidiophores separated by connective cells.
