Species Name | Morphological Characteristics In Vitro | |
---|---|---|
Conidiogenous Cells | Conidia | |
Periconia artemisiae (KUN-HKAS 107384) |
2.5–4 × 1–2 μm, mono- to polyblastic, with 1–2 conidiogenous loci, lateral, or integrated, lateral and terminal, brown to dark brown, inconspicuous, giving rise to solitary conidia, or in short chains. | 5–8 × 4–5 μm globose, brown to dark brown, aseptate, smooth to slightly verruculose. |
Periconia banksiae (≡ Noosia banksiae, CBS H-20587) |
Solitary, lateral, or integrated, inconspicuous, lateral and terminal, with small, pimple-like pores of up to 0.5 µm diam. | Dimorphic: primary conidia (4–)7–10(–13) × (3.5–)4(–5) µm, aseptate, globose to fusoid-ellipsoidal, subhyaline to brown, smooth to verruculose with age, solitary or in short, branched chains. Secondary conidia 5–15 × 4–5 µm, phragmosporous, brown, verruculose, arising from disarticulating hyphal cells, initially in short chains, forming directly on conidiogenous cells when mature. |
P. chimonanthi (KUN-HKAS 107380) |
7–10 × 4.5–6 μm, polyblastic, solitary, erect, lateral and terminal, cylindrical to irregular, luteous to brown, discrete or integrated, determinate, or inconspicuous, percurrent proliferations, with 1–3 conidiogenous loci. | 6–8 × 6–8 μm, globose to oblong, or ellipsoidal, subhyaline to brown or dark brown, smooth to verruculose, solitary or in short chains. |
P. pseudobyssoides (KUN-HKAS 107382) |
4–6 × 2.5–4 μm, monoblastic, solitary, terminal, inconspicuous, with small, pimple-like pores, arising from brown and verruculose hyphae. | 13–16 × 12–15 μm, solitary, globose, reddish-brown, aseptate, verruculose. |
Notes: Conidiophores reduced to conidiogenous cells for all of these species. The morphological characteristics of Periconia banksiae (≡ Noosia banksiae) are adopted from Crous et al. [16].
