ABSTRACT

Three species of Siphomycetes: Rhizopus arhizus, Rhizopus equinus and Rhizopus nigricans, as well as a Septomycete: Emericella nidulans, have been examined by means of a scanning electron microscope. Among the difjerent Rhizopus, this technique showed differences in the appearance of the sporangia. In Emericella nidulans, scanning microscopy enábled one to ascertain that the "Hull cells" were completely hollow and also demonstrated the ornemented aspect of the ascospores.


RESUMO

Três espécies de Sifomicetas: Rhizopus arhizus, Rhizopus equinus, Rhizopus nigricans e um Septomiceta: Emericella nidulans foram examinados em microscopia de exploração. Esta técnica mostrou detalhes não evidenciáveis ao poder de resolução do microscópio óptico, demonstrando ser útil para o diagnóstico em micologia.
