Hello
Presently there is a mushroom season in Czech Republic and I wonder how firmly has the Boletus connect his micelia. I heard, that if you touch (I do not know how gently)young fruiting body hat, it will stop grow more. I suppose because you break the net. IS IT REALY POSSIBLE JUST WITH TOUCH?
Thank you

Why wild carrot Daucus carrota has dark point in the middle of the inflorescence. I hear somethink that is for attracting the birds. they think that is insect and attack the inflorescence. Carrot is pollinate this way. but i am sceptic about birds as pollinator in carrot example because she has fragrance and nectar for pollinators_insect. And why evolution favour this.
