Die Spezies Diaporthe und die asexuelle Form Phomopsis, sind eine Gruppe von pathogenen (schädlichen) Pilzen, "unschädlicher" Endophyten und saprobiontisch lebenden Pilzen. Es sind mehrere hundert Arten bekannt. Interessant sind diese Pilze besonders im Zusammenhang mit der Landwirtschaft und Ackerbau, da Infektionen an Kulturen durch pathogene Arten grosse Schäden anrichten können.

Gattungsbeschreibung
Perithecia formed within the substratum, erumpent to the exterior
"
through an ectostroma or directly through the overlying tissues by
"
means of a more or less elongated perithecial neck; scattered singly,
"
irregularly clustered or in definitely orientated groups; formed within
"
an area of entostromatic development which shows a marginal black
"
ening of the tissues, at least at some points. Asci clavate to cylindric
"
with a refractive ring in the thickened apical wall, sessile, soon freed
"
from their attachment by dissolution of the basal portion and coming
"
to lie free within the perithecium. Paraphyses broad, band-like, pre
"
sent at first but disappearing at maturity. Spores elliptic-fusoid to
"
cylindric, straight inequilateral or curved, two-celled, hyaline, some
"
times appendaged and biseriate to uniseriate in the ascus.
"
In the following key an attempt is made to separate the species with
"
out reference to the host inhabited. As there are often overlapping
"
forms in some groups and as the host is often a great aid in the identification of species, the host is given in parentheses after each species.
