Such a pity that the English names of species in the Wikipedia are usually in fact Latin, while German has funny names for many. Here is a "Krause Glucke" (Frizzy Hen):
Sparassis crispa. No stem. A little different.
In general, there are two categories of mushrooms: pedestal (
Basidiomycota) and tubular (
Ascomycota); the latter may be interesting for you. There are
cup shaped,
balloon shaped,
net shaped even (including
Morchella with smelly goo)...
The TRION game "RIFT" has a whole zone which looks like taken over by mushrooms: the "Ardent Tomain". Watch a
video of gameplay there (best quality in HD resolutions).
