shape: muriform, roughly spherical to irregularly lobed cluster of cells (resembling a blackberry). symmetry: asymmetrical to vaguely radial. wall structure: thick, highly pigmented cell walls. edge definition: distinct, scalloped or lobed contour due to the multicellular composition. surface texture: individual cells appear to have a rough or verrucose surface. internal contents: dense and obscured by heavy pigmentation. color and staining: dark reddish-brown to dark magenta; heavily naturally pigmented (dematiaceous). septation or chains: muriform (multi-septate in intersecting planes, forming a dense ball). other notable features: The wider field image shows other distinct particles, including an apparent skin cell and a separate club-shaped dematiaceous spore (likely Alternaria), indicating a mixed indoor sample.
