Phomopsis hysteriola
General description:
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.
Conservation status:
An assessment would not be appropriate until the taxonomy is properly understood.
Associations:
On dead stems of Heracleum sphondylium, reported by Grove (1935) also from Chaerophyllum temulentum and Sison amomum. His records on Atropa need confirmation.
Distribution:
Scattered throughout southern England and Wales.
Notes:
A provisionally accepted species; molecular data is needed to place it accurately.
