Description of fungi

 

The family Botryosphaeriaceae * is currently made up of at least ten genera and 21 species, the anamorphs of which are divided into 7 fungal genera, are considered to be pathogenic on vines (see the list at the end of the page).
The genus Botryosphaeria was created in 1863; it is originally based on the description of the reference species Botryosphaeria dothidea , and at least 18 species have been described in this genus. Recently, the phylogeny of these species has been reviewed using molecular methods based on the study of several genes (elongation factor, large and small ribosomal subunits, ITS, Beta-tubulin).

 

  • The mycelium of this fungal family is generally white and then becomes pigmented gray-brown to black over time (Figures 1 and 2).
  • The sexual (teleomorphic) form of these fungi is very rarely encountered in nature. FIG. 3 shows the appearance that the sexual form of can have, for example Botryosphaeria parva . The ascospores produced by asci contained in perithecia are hyaline and aseptic at first, they will turn slightly brown, eventually becoming partitioned with age.
  • The asexual (anamorphic) form is materialized by the easy formation of pycnidia . These produce conidia hyaline (pycniospores) for some species, melanizing for others, turning brown with age (Figures 4 to 6).
