I've been mushroon hunting today. I've never seen so many. This one, Anthurus muellerianus, isn't native here. It came from Australia. It is not invasive though, quite rare instead, so one has to be lucky to find one.
I didn't find the English name, maybe Barbara knows. Best regards to her. In German it is called like 'squid fungus'.
I took photographs and my lunch as well. Is was Saffron Milk Cap, chopped, fried, an egg scrumbled over it. Seasoned with pepper, salt and a touch of Rosemary, like my grandmother did.
