Key to
the various lineages in "Botryosphaeria"
This key is in
several parts. The first part splits Botryosphaeria into four major
groups, namely species with Fusicoccum, Diplodia or
Lasiodiplodia or Dothiorella anamorphs and a fourth group consisting of
the B. obtusa/D. pinea complex. Subsequent keys can be used
to identify species within these groups.

1.
Conidia more than 10 µm wide, thick-walled, mostly ovoid
...................................... 2
1. Conidia less than 10 µm wide, thin-walled, fusoid, ellipsoid or ovoid

.......................................... Fusicoccum
and Neofusicoccum
2. Conidia hyaline and remain so for a long time before becoming
dark-walled
and septate,
usually after discharge ..................................
Diplodia/Lasiodiplodia
2. Conidia become dark whilst within the pycnidium

3. Conidia dark-walled and one-septate within the pycnidium, often before
release
from the conidiogenous cells
....................................................................
Dothiorella
3. Conidia dark-walled and aseptate within the pycnidium .............
