There is not specific collective noun for the noun ignorance. The noun ignorance is an uncountable noun; quantities of ignorance are expressed in degrees, for example, some ignorance, much ignorance, total ignorance, etc. A term that expresses ignorance as a collective would be, 'the collective ignorance of a group' or 'the combined ignorance of a group'.
