ABSTRACT
Schroeteria delastrina and 5. poeltii were studied by light and transmission electron microscopy. Schroeteria has traditionally been classified in the Ustilaginales, but karyogamy and meiosis do not occur in spores or in germination hyphae. Spores and Hyphae are multinucleate and the conidia (“sporidia”) arise endogenously. Based on these facts, on the morphology of the spindle pole bodies, on the presence of pores with a pore plug and Woronin bodies at the septa and, on the absence of layering in the cell wall, we conclude that S. delastrina and S. poeltii are anamorphs of Ascomycetes. Consequently, the genus Schroeteria should be exchided from the Ustilaginales.
