Hey, picking mushrooms is a hobby for me, but I didn’t know you can do it on public buses too. Well, you can. Especially in Hungary. This young Pleurotus ostreatus was captured on a coach to Seregélyes, Hungary.
Unique? No, because then here’s another instance of Pleurotus ostreatus growing on a bus, again from Hungary, from Bus No. 27 in Budapest.
The older Ikarus buses seem to have this species (and some others too) by default. Never look under your seat. Never.
