So pleased you enjoyed them Annief. You are a lucky so and so if you have lot's of Boletes, but suspect most may be what used to be called the Red Cracking Bolete, which are not worth bothering about.
If however you have the larger, more fleshy Boletes (in your very own garden!) then you are very fortunate and I suggest at the end of next summer when they should start to appear again, send in some photos to have them checked out, and it sounds to me you are going to be making a lot of Wabbers very envious !
Regarding Truffles, many different species occur in Britain, most being mediocre, but we do get some good edible ones, but Truffles in Britain are clouded in secrecy and I do not know if we will ever get the true picture.
Do please though, sent some examples off to Kew if any more do show, and most important - keep it quiet, otherwise before you know it, you will have strangers digging in your garden, then you will have to buy a vicious dog.
Neil.
