I like taking pictures of fungi. They don’t flee if I get too close: creatures which don’t flee when I get too close are likely to attack instead. Even worse. They don’t move unpredictably when there’s even the slightest breeze, like many plants.
Admittedly, they are often hard to get a good view of: hiding where there’s not much light, half-hidden in vegetal detritus in an overgrown patch of rough ground. But they have an incredible variety of shapes and textures, and sometimes colours which cannot be seen anywhere else in the natural world. And once in a while they’re just a slightly twisted variation on a standard mushroomy shape, with colours which are bland. Lo, scurfy twiglets, Tubaria furfuracea.
