Family Gigasporaceae
Morton and Benny (1990)
|
Members have all characteristics
of the suborder Gigasporineae. In addtion
they form large (usually >200 um) spores asexually with the following morphological
properties:
- The spore wall consists
of a permanent outer layer enclosing a laminate layer, each with different
properties that distinguish species (e.g. color, thickness, reaction in Melzer's
reagent, etc.) and
- The spore contents are
partitioned from that of the bulbous sporogenous cell by a plug or, more rarely,
by a septum.
Two genera are recognized:
Gigaspora
Scutellospora
