Treatment

Apiospora arundinis (Corda) Pintos & P. Alvarado , Fungal Syst. Evol. 7: 205 (2021)

Fig. 2 View Figure 2

Description.

Asexual morph: On WA, hyphae smooth, branched, septate, 1.2–3.5 µm diam. (n = 30). Conidiophores cylindrical, septate, erect, sometimes reduced to conidiogenous cells. Conidiogenous cells erect, subglobose to ampulliform, aggregated in clusters on hyphae, smooth, branched, 5–15 × 1–2.5 µm (x = 8.5 × 6 µm, n = 30). Conidia globose, sub-globose to ampulliform, lenticular, occasionally elongated to ellipsoidal, with a longitudinal germ slit, brown to dark brown, smooth to finely roughened, 6–14 × 4–7 µm (x = 10.5 × 6 µm, n = 30) µm. Sexual morph: Not observed.

Culture characteristics.

Colonies on PDA attaining 5 cm diam, after 4 days at 25 ° C, thick, dense, surface with patches of grey aerial mycelia, margin irregular and undulate, diffuse yellow pigment, reverse yellow.

Specimens examined.

China • Guizhou Province: Guiyang City , on diseased bamboo branch, 5 June 2022, K. M. Yu, living cultures: GUCC 6.1 . and GUCC 6.2 .

Notes.

In the present study, two new isolates ( GUCC 6.1 and GUCC 6.2 ) clustered together with Ap. arundinis ( CBS 133509 ) with high-support values (ML / BI = 98 / 1) in the multi-locus phylogenetic tree (Fig. 1 View Figure 1 ). Morphologically, GUCC 6.1 and GUCC 6.2 have similar conidiophores, conidiogenous cells, and conidia to Ap. arundinis ( Li et al. 2023) . Ap. arundinis was found on various plants, including Phyllostachys praecox , Castanea mollissima , and Brunfelsia brasiliensis in China ( Chen et al. 2014; Liao et al. 2022; Li et al. 2023). The conidia sizes of our collection (6–14 × 4–7 µm) larger than Chen et al. (2014) (5–7 × 2–4 µm) and Liao et al. (2022) (4.5–7.4 × 3.3–4.4 µm). Comparing with the description from Li et al. (2023) (6.4–10.4 × 5.2–8.3 µm), they have similar sizes, but the conidia in this study are slenderer and more elongated. Combining phylogenetic tree and morphology, these strains were identified as Ap. arundinis .
