This issue gives excellent examples for basic mycology, both from mushroom forming basidioymcetes and ascomycetes, including yeasts. The composite title photo shows two fungi, one basidiomycete and a yeast. A mitotic spindle of the mushroom forming basidiomycete Schizophyllum commune, stained for tubulin by immunofl uorescence and for DNA using DAPI (photo: Elke-Martina Jung, Jena) is shown, as well as a fruitbody forming in culture (insert on the left, photo: Nicole Knabe, Jena). Endocytosis of fl uorescein labelled, linear DNA is shown in a second insert (green stain) which is accompanied by a phase-contrast picture of the Saccharomyces cerevisiae cells used (see article by Lang et al. in this issue).
