Jain & Kar (1979) proposed Colligerites to accommodate Involutisporonites kutchensis R.K. Kar & R.K. Saxena 1976, described from the Matanomadh Formation (Palaeocene, 66–56 mya) of Matanomadh, Kutch District, Gujarat, India, with the following diagnosis: “Spores multicellular, coiled, cells generally smaller, rounded in central region and bigger, rectangular in outer region. Spore wall mostly laevigate, sometimes granulose. Pore may be present or absent in each cell.” Several asexual ascomycetes in the family Tubeufiaceae have similar ascospores (Boonmee et al. 2011, Dong et al. 2020).
