I'm no expert in mycology, until recently I had known only around 8 species by name. Those nicely coloured boletes were not two specimens of Boletus satanas but one Boletus calopus, inedible because awfully bitter (but oh so pretty. I know where they grow, I'll get a picture when the rains stop) a well slug-gnawed Boletus erythropus.
Which I found out by showing them to a botanist friend. I was also told that B. erythropus is hardly ever infected with insect larvae but that it's popular among slugs and forest mice. Also, it turns nicely blue when bruised or cut. Mental note: I should read something about the chemistry in mushrooms. I wonder whether the blue colour could be fixed somehow.
It's raining and I'm not going anywhere out until it's sunny. No more mushrooms for a few days, promise.
