Surface structure of the conidium and conidiophore of Stemphylium botryosum

Abstract

Observations with the scanning electron microscope reveal tuberculate prominences up to 0.75 to 1.0 μ high and 0.5 μ wide on the suface of the conidium. The prominences are 1.0 to 1.5 μ apart and in the mature conidia have flattened cap-like tops. The swollen tips of the conidiophores are finely warted.
