Abstract

An ultrastructural study was performed on Arthrinium aureum. The fungi were treated with glutaraldehyde and osmium tetroxide fixation. The hypha and conidia has a concentric membrane system which consisted of multiple membranes of a myelinoid appearance, and continued to the conidia and hypha plasma membrane. The fungi were also treated with periodic acid-alkaline bismuth (PABi) staining after glutaraldehyde and osmium tetroxide fixation. PABi positive materials were found on the marginal glycogen granules, the concentric membrane system and the conidia plasma membrane.
