yes, they are extremely cool and unusual. havent meet them even once - only saw on the pics.

They are really tiny, I find them where there is landscaping bark and lots of rain.

uh, I knew they are not growing on the soil,. but rather on wood chips and manure.
and what about the season (i.e. which months exactly they appear) ?..

April and May around here, when its rainy but not yet too hot in the summer.
