Hello, dear friends.
My name is Olga and I am an amateur mycologist from Israel.
Recently we found here in Israel, on sandy soil, several large mushrooms, which look very much like those, published here - Lyophyllm hypoxanthum/Calocybe hypoxantha, or, to be exact, I think, Lyophyllum hypoxanthum var. occidentale - with more pale, whitish cap and slightly greying flesh.
I just wanted to add, that our mushrooms were found near trees of Acacia saligna and Casuarina, not under Cupressus trees
From the beginning I thought, it is some species of Leucopaxillus genus, but finally I got to this page and saw the pictures, published here, and understood, that "this is our boy".
I started to look for the information in the internet about this species, and understood, that it is quite rare. I did not find an information about it's edibility or toxity. Do you treat this mushroom as edible, unedible or poisonous?
And also I read in the beginning of this topic, that according to your observation, these mushrooms' fruit bodies remain for a long time, maybe month or more, and do not decay. Does it mean, that they could contain antibiotic material, that preserves them from decay, just like it is in mushrooms of Leucopaxillus genus? Do other species of Lyophyllum genus have this characteristic too, according to your observation?
I'd be glad to hear, what you say about this fungi, as it is somenthing new for me and it looks just beautiful.
Here are some of our pictures, taken in Israel in winter mushroom season (our season lasts usually in October-Februar and comes to its end now).
Thank you and have a pleasant day
