Conidiophores cylindrical, hyaline to light brown, simple, formed at the conidiomatal wall, (24 –) 28 – 52 (– 60) μm (av. = 43 μm, n = 20) long. Conidiogenous cells subcylindrical to cylindrical, smooth-walled, produce conidia acrogenously.

Culture characterisctics: — Culture growth on PDA is initially white, becoming yellowish after 3 – 5 days. The colony is flat, with an irregular edge, texture uniform, producing dark green to black pigment after 7 – 10 days. Conidiomata sparse, irregularly distributed over agar surface, black mucous conidia were produced on the colony.	en	Du, Zhuo, Hyde, Kevin D., Yang, Qin, Liang, Ying-Mei, Tian, Cheng-Ming (2017): Melansporellaceae: a novel family of Diaporthales (Ascomycota).

Fan, 11 Jul 2013 (BJFC-S 955, living culture, CFCC 51729). Notes: — Melansporella juglandium is the type species of Melansporella, and only occurs on Juglans regia. Isolates were identified as Melansporella juglandium based on holomorphic morphology characters, host, and high support in the phylogeny (MP / ML / BI = 100 / 96 / 1). Hence, we treat this taxon as a novel species of Melansporella.	en	Du, Zhuo, Hyde, Kevin D., Yang, Qin, Liang, Ying-Mei, Tian, Cheng-Ming (2017): Melansporellaceae: a novel family of Diaporthales (Ascomycota).
