Semicentenialea rex, as a colony and under the microscope

The images show Semicentenialea rex both as a colony and under the microscope. After eight weeks of growth, the fungus forms a small colony on the culture plate. The microscopic images reveal a network of hyphae with so-called clamp connections – structures that connect adjacent cells in the hyphae of basidiomycete fungi. To follow fungal development, the researchers stained the nuclei pink and the cell walls blue. Three types of swollen cells can be observed within the hyphae: basidium-like cells, teliospore- or probasidium-like cells, and intercalary swellings. These structures are examined in greater detail in the following figures.
