 Gyroporus cyanescens is an ectomycorrhizal species that has a broad host range . Fruit bodies of Gyroporus cyanescens grow singly or scattered on the ground in deciduous and mixed forests . Often found in association with birch and poplar , the fungus tends to prefer sandy soil , and also frequents road banks and woodland edges . Fruiting occurs in summer and early autumn . Fruit bodies can be parasitized by the mold Sepedonium ampullosporum . Infection results in necrosis of the mushroom tissue , and a yellow color caused by the formation of large amounts of pigmented aleurioconidia ( single @-@ celled conidia produced by extrusion from the conidiophores ) .
