Stagonosporopsis stuijvenbergii

Ciri dan struktur

Colonies after 7 d at 25 °C, on OA reaching 75–80 mm diam, floccose aerial mycelium, olivaceous to pale olivaceous, whitish to pink near the edge, margin regular; reverse iron grey. On MEA reaching 65–70 mm diam, margin regular, aerial mycelium floccose, vinaceous buff with olivaceous edge; reverse darker brown with olivaceous black edge, buff near the centre. On PDA reaching 70–75 mm diam, margin regular, covered by floccose aerial mycelium, olivaceous, olivaceous black towards periphery, with pinkish to pale brown edge; reverse iron-grey, buff towards periphery. NaOH spot test negative on OA.

Habitat dan peran ekologis

Colonies after 7 d at 25 °C, on OA reaching 75–80 mm diam, floccose aerial mycelium, olivaceous to pale olivaceous, whitish to pink near the edge, margin regular; reverse iron grey. On MEA reaching 65–70 mm diam, margin regular, aerial mycelium floccose, vinaceous buff with olivaceous edge; reverse darker brown with olivaceous black edge, buff near the centre. On PDA reaching 70–75 mm diam, margin regular, covered by floccose aerial mycelium, olivaceous, olivaceous black towards periphery, with pinkish to pale brown edge; reverse iron-grey, buff towards periphery. NaOH spot test negative on OA. Phylogenetically, S. stuijvenbergii is most closely related to S. weymaniae, another novel species collected from Dutch soil in this study (Figure 1). However, S. stuijvenbergii is distinguishable from S. weymaniae by the colour and the size of its pycnidia, being brown and measuring 200–1000 × 195–930 μm in S. stuijvenbergii, whereas S. weymaniae produces whitish pycnidia, measuring 330–650 × 250–550 μm. Furthermore, S. weymaniae produces microconidia and chlamydospores, which were not observed in S. stuijvenbergii. Although there are several reports that Stagonosporopsis spp. could survive in soil for a short time (Vaghefi et al. 2016), this is the first record of a Stagonosporopsis species only known from soil (Domsch et al. 2007).

Reproduksi

The Netherlands. Gelderland province, Meteren, from garden soil, Mar. 2017, S. van Stuijvenberg (holotype designated here CBS H-24109; living ex-type culture CBS 144953 = JW 132011). Conidiomata pycnidial, produced on the agar surface, scattered or aggregated, solitary globose to subglobose, or 4–7(–10) confluent and irregularly-shaped, brownish, glabrous, ostiolate, 200–1000 × 195–930 μm; with 1–2 slightly papillate ostioles, sometimes elongated to a short neck; pycnidial wall pseudoparenchymatous, 4–5 layers, 6.5–35 μm thick, outer layers composed of brown, flattened polygonal cells, 9.5–33 μm diam. Conidiogenous cells phialidic, hyaline, smooth, globose, ampulliform or lageniform, 4.5–9 × 4–8 μm.
