Anamorph: conidiomata in short linear rows, the ostioles erumpent from the host tissue. Conidia (alpha-conidia) 7.5-9 x 3-3.5 µm, fusiform (rarely fusiform-cylindrical), hyaline, aseptate, smooth, usually with two large guttules, without an epispore or gelatinous sheath. Beta-conidia not seen.
Teleomorph: not known.
An assessment would not be appropriate until the taxonomy is properly understood.
On dead stems of Heracleum sphondylium, reported by Grove (1935) also from Chaerophyllum temulentum and Sison amomum. His records on Atropa need confirmation.
Scattered throughout southern England and Wales.
