Micapra have horizontal pupils, long-ish fluffy ears, a rabbit-like nose, and sometimes a branching tail. Most notably, they have fungal fruiting bodies on their heads, which may come in the form of a "hat" or "horns". Their "fur" is actually small strands of mycelium, and they often have neck fluff resembling a mushroom's ring. They are 4'1'' / 1.24m tall on average.
Micapra are adept at plant-related magic, like helping plants grow; it's most often focused on fungi, though (which aren't even plants... they're just magical like that).
Micapra may be solitary or live in colonies, it depends entirely on the individual. They prefer to live in forests, though they can be found in any environment.
