Phyllosticta musaechinensis is weakly pathogenic on leaves of Musa sp. It grows slowly on PDA. Sexual and spermatial states were not observed.

Type: — CHINA. Chongqing Municipality: Yubei District, Longtou Temple Park , on leaves of Musa sp. , 21 September 2012, Shiping Wu, (CQ12097, holotype); ex-type living culture = GZAAS6.1247 = MFLUCC13-0907 View Materials = ICMP 20111 View Materials ).

Etymology:— From Musa , the host and chinensis, in reference to the first collection of the species on a banana host in China.

Weakly pathogenic on leaves of Musa sp. , slightly discoloring leaves yellow, with black, shiny conidiomata forming on healthy green, or yellowing parts of leaves. Sexual state: Unknown. Asexual state: Pycnidia 45–145 µm (= 93 µm) diam. subcuticular to erumpent, solitary or clustered in small groups, black, shiny, globose or subglobose, with a rounded ostiole at the center. Conidiogenous cells cylindrical or conical. Conidia 14–18 × 8–12 µm (= 17 × 10 µm), hyaline, aseptate, coarsely guttulate, ellipsoidal or clavate, thin- and smooth-walled, surrounded by a mucilaginous sheath 0.5–3.5 µm thick, apex tapering, straight to curved, appendage 4.0–18.5 µm (= 12 µm) long. Spermatial state: unknown.

Colony on PDA bluish black to black, without aerial mycelium, irregular, raised to about 0.7 mm, reaching 14.2– 12.5 mm diam after 60 d at 28°C. Pycnidiasolitary or aggregated in colony, black. Conidia 15.5–22.5 × 8.5–13 µm (= 18 × 11 µm), hyaline, aseptate, coarsely guttulate, ellipsoidal, clavate or irregular, thin- and smooth-walled, surrounded by a mucilaginous sheath or not, apex tapering, straight to curved 4–18 µm (= 11.6 µm). Spermatia not formed.

Known distribution:— China.

Host:— Musa sp.

Additional material examined:— CHINA. Chongqing Municipality: Yubei District, Longtou Temple Park , on leaves of Musa sp. , 3 August 2013, Shiping Wu ( CQ13018 ); living culture = GZAAS6.1384 .
