Translation:I do not pick these mushrooms because I do not know them.
Out of curiosity: What is the most common term for 'sbírat houby' in english? to collect mushrooms, to pick mushrooms, to gather mushrooms ... ? By the way, I love it ... :-)
Probably to pick mushrooms: I like to pick mushrooms. Are you going to pick mushrooms today? Who picked those mushrooms? And so on...As for myself, I have never picked them:)
