Chestnuts versus earthstar mushrooms, carnival candy slime mold, etc.

Today in the morning, I went for a walk in the usual woods.

I found a chestnut prickle at my feet. This one had chestnuts inside, but the rest ones scattered around had all been eaten by wild monkeys. 


A collared earthstar mushroom has started to appear. Unlike an ordinary earthstar mushroom, it has a pointed pear-like shape when it is young.

When mature, the thick outer bark splits open radially from the apex.
The outer bark splits open in a star-like shape and everted outwards.
A collared earthstar mushroom as well as an ordinary earthstar mushroom remind me of chestnuts. In fact, the earthstar mushroom is called “Tsuchi-Guri” in Japan. Tsuchi means soil or earth and Guri is a chestnut.


Carnival candy slime mold or cotton candy slime mold (Arcyria denudata) occurred on decayed used logs (Quercus spp.) for shiitake mushroom cultivation.

The fruiting bodies seem pastel reddish and the stalk is reddish orange color. I think the spores have not yet been released.

Normally, a polypore fungus (bracket fungus) does not have a stalk, but this one has a very long stalk. Really?

View from the other side. It looks like a dead branch, not a stalk.
