ABSTRACTIt has been suggested that the anamorph ofOphiostoma francke-grosmanniaeis a species ofPhialocephalawith phialidic conidium development. This would make it the only species inOphiostomawith aPhialocephalaanamorph. Light and fluorescence microscopy seemed to confirm the presence of phialidic conidiogenous cells. However, scanning and transmission electron microscope observations revealed tightly packed, yet distinct annellations in the apical region of the conidiogenous cells. This is indicative of the percurrent enteroblastic proliferation that is diagnostic ofLeptographiumanamorphs ofOphiostoma.The anamorph ofO. francke-grosmanniaeshould, therefore, be disposed inLeptographium.
