Dictyosporium digitatum sp. nov. is described from a fallen, decaying herbaceous stem. It is sporodochial and characterized by cheiroid conidia consisting of 4–8 parallel, tightly appressed arms which are flattened in one plane. Arms ascend from a more or less triangular basal cell. The apex of each arm is digitate, distinctly thin-walled, hyaline, straight or flexuous, incurved or even curled. The morphological distinction between D. digitatum and other closely related species in Dictyosporium, Cheiromyces and Cheiromycella is discussed.
