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
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 ............. "B." obtusa/D. pinea
