Abstract Mycelial development of seventy-three strains of black yeasts and related fungi were studied, and numbers of nuclei per hyphal cell were counted. Two main patterns were apparent in expanding hyphae, viz. (1) uninucleate expanding hyphal cells, septum formation strictly following mitosis, and (2) multinucleate, branched, aseptate hyphal tips, septa being formed in a later stage, leading to oligo- or uninucleate mature cells. Characteristic genera in the two groups areExophiala andAureobasidium, respectively. InZasmidium and in someRamichloridium species all mycelial cells are oligonucleate. The character is indicative for relationships at the family level in black yeasts.
