I just posted a song about mushroom-hunting in La Lilandejo. I only know it in Esperanto, but something in the back of my head whispers that it is of Danish origin. Does anybody recognize it (text or tune or both) or know anything about it?
Fungoj
The meaning is roughly as follows:

1. In the autumn forest, among the treetrunks
I go searching, because now it's 'shroom season!
To a merry melody, I put them in my basket
With knife and fingernails, O you lovely fungi!

In the autumn forest, the flowers have already withered,
But the fungi without stinginess shine in colours:
White, read, with a hat on a stick, here an umbrella;
Some shine golder, oh, what lovely colours.

Some taste like an apple, are indeed welcome,
But dangerous to humans are the poisonous ones!
"Research is of paramount necessity! More important than the color,"
Said my grandfather, "are their contents."

Any information will be gratefully received.
