Lyophyllum shimeji, commonly known as the hon-shimeji is an edible species of fungus in the family Lyophyllaceae that grows in pine forests, often near man-made roads.

It was originally only known from Japan, Korea and China, but presently has a known distribution that includes Russia, Estonia, Scandinavia, Czechia and Spain, as well as USA and Canada.

[1][2] It is particularly widespread in lichen pine forests in Sweden, Finland and Norway, after being confirmed from these countries as late as 2011.
