Abstract: | The autofluorescence (primary fluorescence, AF) of the freshly collected fruiting bodies of the fungus Macrolepiota rhacodes was studied in a Zeiss Jenalumar fluorescence microscope at a blue and a green excitation. The strongest yellow AF at blue excitation was displayed
by irregular granules on the surface of the fungal pileus. A weaker yellow-green AF was exhibited by spherical cells and hyphae
in the central part of the pileus while basidiospores emitted somewhat stronger AF. At green excitation, a considerable red
AF was emitted only by basidiospores, other parts of the pileus showing a very weak red AF. M. rhacodes AF is much weaker than the AF of wood-rotting fungi, such as Fomes fomentarius, Daedalea quercina, Piptoporus betulinus, Fomitopsis pinicola and others. |
