What Are They?

I have observed something which was new to me, but may not to you, at Cerok Tokun. They appeared after the few days of rainfalls, just like the mushrooms. I am now able to know something about them with the help of technology.

With much struggles, I decided to put up the pictures thus to check my level of negligence. Please bombard my foolishness if you are able to tell the identity. I shall be even happier if I find out you are like me.
