Sulfur-yellow honey fungus (Latin Hypholoma fasciculare ) is a poisonous mushroom from the genus Hypholoma of the Strophariaceae family.

Sulfur-yellow honey fungus grows on stumps, on the ground near stumps and on rotten wood of deciduous and coniferous species. It is often found in large groups.

The cap is 2-7 cm in ∅, first bell-shaped , then prostrate , yellowish, yellow-brown, sulfur-yellow, lighter along the edge, darker or reddish-brown in the center.

The pulp is light yellow or whitish , very bitter, with an unpleasant odor.

The greenish color of the plates and the cap makes it possible to distinguish this mushroom from most of the so-called "honey agarics". Gray lamellar honey fungus (Hypholoma capnoides) grows on pine stumps, its plates are not greenish, but gray.

I believe that at the competition of the most ordinary-looking mushrooms, the sulfur-yellow mushroom (or false foam) will never win the main prize: it will not be possible to attract the attention of the jury.
