A few shots of the 5th kingdom, Fungi. Mushrooms are the most common example of fungi, but there are others. Fungi had been classed with the Plant kingdom in older taxonomies, but they now have their own kingdom. Fungi, according to my editor’s bible, are

nongreen eukaryotic organisms with cell walls that differ chemically from those of green plants, and they have different modes of nutrition. There are 3 divisions within the kingdom Fungi: Zygomycota (zygomycetes), Basidiomycota (basidiomycetes), and Ascomycota (ascoymcetes). Some divisions in the kingdom Protista (including Myxomycota, Oomycota, Plasmodiophora, and Chytridiomycota) were formerly considered to be fungi. (357)

Not being a mycologist, I don’t even bother to identify the fungi in the photos below to order, let alone genus or species. Kingdom is good enough for me, for now!
