Eyelash Cup Fungus
Fungi can be divided into two groups – basidiomycetes and ascomycetes. Basidiomycetes (gilled mushrooms, coral fungus, hedgehog mushrooms, puffballs, bird’s nest fungus) produce spores on the surface of microscopic cells called basidea. Ascomycetes (morels, cup fungi, stinkhorns) produce their spores within microscopic sacs (asci). The slug in this photograph is dining on an ascomycete — eyelash cup fungus (Scutellinia scutellata), the rim of which bears many stiff, eyelash-like hairs.
