ellipsoid, moderate in size, beakless, with several transverse
and longitudinal septa, solitary or in short chains. Solitary, short,
apical secondary conidiophores may occur. The species from this
section occur on Umbelliferae.
Note: This section was first recognised by Pryor & Gilbertson
(2000) based on sequence data of the ITS and mitochondrial SSU.

Type species: Alternaria sonchi Davis
Diagnosis: Section Sonchi is characterised by subcylindrical,
broadly ovoid, broadly ellipsoid or obclavate, (medium) large
conidia, single or in short chains, with multiple transverse and few
longitudinal septa, slightly constricted at the septa, with a blunt
taper which can form secondary conidiophores.
Notes: The species-group was described by Hong et al. (2005)
based on molecular data of the GAPDH and Alt a 1 regions.
Lawrence et al. (2013) included A. brassicae as a basal lineage
in sect. Sonchi, which is supported as a monotypic lineage in our
analyses. The species from section Sonchi occur on multiple hosts
within the Compositae.
