Affinities:
McIntyre and Brideaux, 1980, p. 25: Kallosphaeridium ?agglutinatum differs from K. ?granulatum (Norvick in Norvick and Burger) Stover and Evitt, 1978 in being larger and possessing a dense granulate to microrugulate ornament compared to the granulate, baculate or clavate ornament of the latter.
