Blue, red and yellow mushrooms I found on my forest walk

It's already mid-October; I haven't seen slime molds around lately. I think the occurrence of slime mold was low this year. This summer was extraordinary hot, so this probably had a bad effect for slime molds. When I go for a stroll through the forest, all jumped into my eyes are mushrooms.

Actually, it rained heavily last night. Today it's cloudy, and it is a little dark inside the forest, but plants seem lively after the rain. When I wandered along my favorite forest path, I found many traces of wild boar digging. I think they were probably searching for earthworms under the fallen leaves. I wonder if wild boars are okay with eating that stuff.

This is a truly eccentric blue mushroom. I usually find it in the beech or oak forests, but today I found it occurring in the middle of the unpaved forest road. I think it's probably a Japanese blue mushroom (Ruri-hatsu-take) and its scientific name is not Lactarius indigo, but a different species, Lactarius subindigo, which is distributed in eastern Asia (Japan, Southeast Asia to India). But when I looked it up online, it said it was a "rare mushroom," so I might not be right.

On the other hand, this is a vermilion color mushroom. This mushroom is also commonly seen in woodlands, but it was growing by the forest roadside.

A small, bright yellow fungus had grown on rotten wood. It's called a Byo-take mushroom, and is small, less than 5mm in diameter. It's very noticeable.　In English-speaking countries, it is known as yellow fairy cups or lemon disco. It is a saprophytic fungus. Its Japanese name, Byo-take, comes from the fact that the fungus resembles a nail that is used to fasten something.
