Description of Auraspora

The type species is A. canningae Weiser and Purrini, 1980 in the male gonads of Lepidocyrtus lignorum (Collembola, Tomoceridae). Dimorphic (?), diplokaryotic and monokaryotic. Meiosis unknown. Transmission unknown. Merogony: unknown. Sporogony: apparently two developmental sequences. In one sequence, tetra and octonucleate plasmodia give rise to free binucleate sporoblasts and spores. The other sequence, gives rise to several uninucleate sporoblasts, within sporophorous vesicles. Spores: free spores, 45 x 22.5 µm are pyriform and binucleate, the 2 nuclei differing in shape. The endo and exospore are thick, the exospore having an irregular, foamy character. Polaroplast is lamellar. Polar tube is isofilar with 89 coils. No data are available on the second type of spore. Comment: this is an incompletely known genus with no satisfactory illustrations for reproduction.
