conidiophore_position_solitary
solitary
A solitary elongating secondary conidiophore usually develops from each primary conidium apex. However, it is not uncommon in this taxon for a group of 2-3 subparallel secondary conidiophores to arise from a common base cell or for a pair of conidiophore branches to originate in a spreading dichotomous manner just below a terminal conidiogenous locus.
