Click here for more information on apple rot fungi Figures J-N. Basidiomycota. Figure J shows toadstools of Coprinus comatus , one of the 'ink-caps'. Figures L and M show microscopical cross sections of the gills of a typical toadstool. Figures O, P. Oomycota. Sexual reproduction is shown for a species of Saprolegnia in Figure O .
Asexual reproduction is by release of motile zoospores from a sporangium.
Figure P shows a single sporangium of Phytophthora palmivora . The sporangia are wind-dispersed, land on a plant surface and their contents differentiate to produce zoospores . These features are important in practice because they can provide targets for the actions of antifungal agents. Fungi are haploid , whereas the other major groups of eukaryotes are diploid. Fungal cell membranes contain ergosterol , whereas animals have cholesterol and plants have sitosterol and other 'phytosterols'.
