DESCRIPTION<\/b>
\nAsexual form<\/i><\/b>: Point-like colonies, sometimes confluent and effusive, blackish-brown to black, 100-400 \u00b5m in diameter. The mycelium is both superficial and immersed in the substrate; the superficial part is composed of septate, smooth-walled, pale brown to olivaceous hyphae, 2-7 \u00b5m thick, branched and anastomosed. The immersed part is sparse, composed of pale olivaceous brown hyphae, 1 to 4 \u00b5m thick. The stem cells of the conidiophores emerge on the mat formed by superficial hyphae, and are barrel-shaped or lageniform, measuring 4-8 \u00d7 3-6 \u00b5m. The conidiophores are erect or erumpent, simple, cylindrical, straight or flexuous, sometimes branched, hyaline, 30-80 \u00b5m long and 3-6 \u00b5m in diameter, with multiple thick brown to dark brown transverse septa. The conidia are curved, with the ends bent inwards (horn-like), brown to dark brown, with a hyaline germinal cleft. They are smooth-walled, measuring 16-21 \u00d7 11-15 \u00b5m in frontal view and 8-11 \u00b5m thick in lateral view, tapering at the horn ends to 2-4 \u00b5m.
\nThe sterile acrogenous cells are hemispherical, pale brown, 5-11 \u00d7 5-7 \u00b5m in size.
\nCulture characteristics: Colonies are flat, spread out on MEA medium and have a moderate aerial mycelium, with a yellow underside. <\/p>\n

Asexual form<\/b> is not known.<\/p>\n

NOTES <\/span><\/b>
\nArthrinium luzulae<\/i> is the only species with inward-curving conidia. The non-type specimen identified here matches descriptions by Ellis & Ellis (1951), Scheuer (1996) and Minter & Cannon (2018). Genetically, it is related to specimens identified as Ar. curvatum <\/i> (which have outwardly curved conidia), suggesting that the entire clade containing these samples may have an ancestor with curved conidia (a characteristic not present in other species of Arthrinium<\/i>).<\/p>\n
