ABSTRACT
The development of ascospore ornamentation in Elaphomyces granulatus and E. persoonia was examined by light and electron microscopy. Although early events of ascosporogenesis were not observed, the delimitation of ascospores involved two unit membranes whose origins were not determined. Subsequent events revealed a pattern of ascospore wall development that resembles that described in other higher ascomycetes. However, the derivation of episporal ridges, the formation of a gelatinous, perisporal matrix, and the deposition of tertiary wall material between the epispore and ridge, collectively distinguish ascospore ornament morphogenesis in these two species from that in other taxa.
