Abstract

Microspore assemblages from the Six Inch Mine coal seam and associated shales at Quarnford, Staffordshire, northern England, were collected and studied. Three new genera, Discernisporites, Mooreisporites, and Proprisporites, and seven new species are erected and described. The maceration techniques developed for obtaining specimens from the shales in comparable condition to those from the coal seam are also described. It was found that spores belonging to the genus Florinites were dominant in the marine shales and that the variety of species in the shales was greater than that of the seam. Chaloner's discussion gives an alternative hypothesis for the high percentage of conifer pollen in the marine shales relative to that of the coal and nonmarine shales.
