the Gnomoniaceae, Diaporthales - The Gnomoniaceae are
characterised by ascomata that are generally immersed, solitary,
without a stroma, or aggregated with a rudimentary stroma, in
herbaceous plant material especially in leaves, twigs or stems,
but also in bark or wood. The ascomata are black, soft-textured,
thin-walled, and pseudoparenchymatous with one or more central
or eccentric necks. The asci usually have a distinct apical
ring. The Gnomoniaceae includes species having ascospores that
are small, mostly less than 25 micrometer long, although some
are longer, and range in septation from non-septate to one-
septate, rarely multi-septate. Molecular studies of the
Gnomoniaceae suggest that the traditional classification of
genera based on characteristics of the ascomata such as position
of the neck and ascospores such as septation have resulted in
genera that are not monophyletic. In th
