Proliferodiscus ingens

Ciri dan struktur

Sexual morph not observed. Asexual morph on OA. Vegetative hyphae hyaline, smooth-walled, septate, branched, 1.5–3 μm wide, lacking chlamydospores. Sporulation abundant, conidia formed in conidiomata. Conidiomata produced on OA in 2–4 wk, solitary or aggregated, subglobose, unilocular, superficial, 250–1000 μm wide, dull green to grey olivaceous, almost glabrous to completely covered with hairs, opening with an irregular rupture. Conidiophores hyaline, smooth-walled, septate, sometimes branched at the base and above, conidiogenous loci formed terminally. Conidiogenus cells enteroblastic, hyaline, smooth-walled, navicular to subulate, tapering towards apices, 8–15 × 1–2 μm; collarettes hardly visible, cylindrical, < 1 μm long, opening 0.5–1 μm, periclinal thickening sometimes visible. Conidia hyaline, smooth-walled, aseptate, cylindrical to ellipsoidal, straight, with both ends rounded, 2.5–3(–3.5) × 1–1.5 μm, mean ± SD = 2.9 ± 0.2 × 1.4 ± 0.1 μm, L/W ratio = 2.1. Colonies on OA raised with entire to crenated margin, buff to pale olivaceous grey, white at the margin, with umber to black spots due to conidiomata, aerial mycelium sparse, white, reverse buff to cinnamon, 1–2 mm diam. in 2 wk, 2–3 mm diam. in 4 wk. Colonies on SNA flat to very low convex with entire to fimbriate margin, white, lacking aerial mycelium, reverse same colour; 1–2 mm diam. in 2 wk, 2–3 mm diam. in 4 wk.

Habitat dan peran ekologis

Strain GLMC 1751, described here as Proliferodiscus ingens, was isolated from Prunus avium in Baden-Württemberg. Only the asexual morph of this fungus was observed. Asexual morphs have previously rarely been observed in the genus Proliferodiscus and no complete description is available. However, Baral and Kriegelsteiner (1985) and Dennis (1949) mention an asexual morph of Pr. pulveraceus. Dennis (1949) observed multilocular pycnidia with slender conidiophores (10–12 μm long) and spherical conidia (1 μm diam.), whereas Baral and Kriegelsteiner (1985) described oval conidia, measuring 1.5–1.7 × 1.2–1.4 μm, produced on verticillately branched conidiophores. In contrast to the description of Dennis (1949), the strains observed here produce unilocular pycnidia. Conidia of Pr. ingens are larger than conidia of Pr. pulveraceus in both descriptions. The asexual morph of Pr. ingens differs from that of the other Proliferodiscus strains observed in this study by producing larger, darker conidiomata, a different conidial shape and a lower growth rate. The closest match in a blastn search with the ITS sequence of strain GLMC 1751 with 97.7% identity is “ Hyaloscyphaceae sp. 2” strain ICMP 18979 from symptomless leaves of Nothofagus fusca in New Zealand (JN225935, Johnston et al. 2012).
