DESCRIPTION<\/strong>
\nAsexual form<\/i><\/b>: Colonies <\/i>on hosts punctiform, pulvinate to effuse, sometimes confluent, black 80-220 \u00b5m in diameter. Micelio<\/i> consisting of submerged and superficial layers of hyaline to pale brown, branched and septate hyphae, 1.5-5 \u00b5m wide.<\/i> Conidiophore stem cell<\/i> spherical to ampuliform, attached to the superficial mycelial web by a basal cell of irregular morphology 2-4 \u00b5m in diameter. Conidiophores <\/i> erect, simple, straight or flexuous, cylindrical, smooth-walled, hyaline except for broad, transverse brown or dark brown septa 40-100 \u00b5m. Conidia<\/i> brown with 2 concentric rings paler than conidia in frontal view 9-12 \u00b5m in diameter, in lateral view irregularly triangular or polygonal 10-14 x 8-10 \u00b5m. Cells<\/i> sterile<\/i> smaller and paler than conidia, globose to ellipsoidal, containing large, hyaline, refracted granules. <\/span>
\nAsexual form<\/b> is not known.
\nNOTES <\/b>
\nArthrinium austriacum<\/i> is characterised by the concentric rings of its conidia seen in frontal view. These rings are also present in Ar. puccinioides <\/i>but this species has regularly polygonal (never rounded) conidia in frontal view. In lateral view, conidia of Ar. austriacum <\/i> resemble those of Ar. fuckelii <\/i>and Ar. morthieri <\/i> because of their irregularly triangular or polygonal morphology, but Ar. morthieri <\/i> has oblong or irregular conidia in frontal view<\/p>\n
