Arthrinium sporophleum

Ciri dan struktur

Asexual morph: Mycelium consisting on smooth hyaline branched hyphae, 2–5 µm in diameter. Colonies oval to irregular, dark blakish brown, 300–1200 × 150–650 µm. Conidiophore mother cells sub-cylindrical, hyaline to pale brown, measuring 5–7 × 5–7 µm (n = 20). Conidiophores straight to flexuous, cylindrical, hyaline except for the thick brown to dark brown transversal septa, 30–130 × 2–4 µm (n = 20). Conidia brown, smooth, lemon-shaped in face view, measuring (10–)11–14(–15) × (5–)6–8(–9) µm (n = 45), triangular with the outer edge curved and rounded angles in side view, measuring 5–8 µm thick. Sterile cells paler than conidia, subspherical or triangular, 5–8 µm wide. Culture characteristics: on MEA 2% colonies cottony, white with grey patches, reverse pale grey.

Habitat dan peran ekologis

Arthrinium sporophleum is the only species of Arthrinium with lemon-shaped conidia. Kunze (1823) considered that Sporophleum gramineum represents a synonym of this species, and Cooke (1954) considered A. sporophleoides Fuckel a synonym of this species too. The only sample analyzed in the present work fits the descriptions of this species by Kunze (1823), Ellis et al. (1951), Ellis (1965) and Scheuer (1996). This sample was found in Juncus sp., but this remarkable species has been often reported from Carex sp. hosts (Ellis 1965). Interestingly, other species occurring in Carex sp. present also conidia with unusual shapes, e.g. A. puccinioides (polygonal), A. curvatum var. minus (curved), and A. caricicola or A. japonicum (fusiform).

Arthrinium arundinis: Spain: Galicia: Santiago de Compostela, city garden, culms of Bambusa sp., 11 Jan. 2018, A. Pintos 11118A (MA-Fungi 91722).
