Minutiella pruni-avium

Ciri dan struktur

Sexual morph not observed. Asexual morph on SNA. Vegetative hyphae hyaline, smooth-walled, septate, branched, 1–3 μm wide, lacking chlamydospores. Sporulation abundant, conidia formed directly on hyphal cells, in conidiomata and by microcyclic conidiation. Conidiophores on hyphae reduced to conidiogenous cells, conidiogenous loci formed terminally. Conidiogenous cells enteroblastic, hyaline, smooth-walled, mostly reduced to mere openings with collarettes formed directly on hyphal cells, discrete phialides rare, navicular, constricted at the base, 5.5–14.5 × 1.5–2.5 μm; collarettes rarely visible or flaring, < 0.5–3 μm long, opening 0.5–1.5 μm, periclinal thickening sometimes visible. Conidia aggregated in masses around the hyphae, hyaline, smooth-walled, aseptate, oblong to ellipsoidal, mostly straight, sometimes slightly curved, with both ends rounded, sometimes with a prominent scar on one end, (2.5–)3–5(–6) × 1–1.5(–2) μm, mean ± SD = 3.9 ± 0.9 × 1.4 ± 0.2 μm, L/W ratio= 2.8. Conidiomata produced on OA in 2–4 wk; solitary or aggregated, globose to subglobose, unilocular, immersed to superficial, 50–340 μm wide, olivaceous to black, mostly glabrous, sometimes with a few hairs, opening with an irregular rupture. Conidiophores reduced to conidiogenous cells. Conidiogenus cells enteroblastic, hyaline, smooth-walled, conidiogenous loci formed terminally, discrete phialides, globose to ampulliform or navicular, 3.5–7.5 × 2–3.5 μm, opening 0.5–1 μm, periclinal thickening sometimes visible. Conidia hyaline, smooth-walled, cylindrical to ellipsoidal, sometimes slightly curved, with both ends rounded, (2.5–)3–4.5(–6) × (1–)1.5–2(–3) μm, mean ± SD = 3.8 ± 0.8 × 1.7 ± 0.4 μm, L/W ratio = 2.2.

Habitat dan peran ekologis

Two strains of Minutiella pruni-avium were isolated from wood of Prunus avium. The LSU sequences of these strains differ in three and one nucleotides from those of M. tardicola and Minutiella sp., respectively. The ITS region shows 11 differences to M. tardicola and 9 differences to Minutiella sp. The TUB sequence of M. tardicola and Minutiella sp. differ in one nucleotide, however, in 35 and 33 nucleotides compared to M. pruni-avium. Minutiella pruni-avium differs from Minutiella tardicola and the strains of Minutiella sp. by forming larger conidiomata, longer discrete phialides and flaring collarettes of up to 3 μm. The closest match in a blastn search with the ITS sequence of strain GLMC 1624 is the type strain of Minutiella tardicola CBS 121757 with 97.9% identity (NR132006, Damm et al. 2010).
