It can get as high as 35° , that is the hottest I have seen here .We have picked upto 40 litres of the Winter chanterelles in one day ,we love to pick and my wife used to take a few baskets per week into work each was about 20 litres and that went on for weeks .Our new place has been much harder to find but we will as you have to learn the forest and we know they are here .
In Finland there is a thing "Everyman's right " ( I hope I haven't told this before !) we are allowed to pick from anywhere as long as it is not within site of the owner's house -and you can sell the pickings without paying tax on the earnings .
Lots of people in the countryside leave the ones they have picked and an honesty box for the money .
There is so much forest here that universities from all over Europe come to see the fungi as some forests have not been looked after and are basically wild .
