It fruits after warm summer or autumn rain, typically when daytime temperatures sit around 12 to 20 C and the ground stays damp. A good soaking followed by mild, humid days a week or so later usually brings them up.
It grows only in association with birch, so look under birch trees in mixed woods, heaths, parkland and damp birch scrub. It favours acidic, moist soils and often appears in mossy or grassy ground near the base of the trees.
The flavour is mild and the flesh turns soft and can go slimy when cooked alone, so it is best used in mixed mushroom dishes rather than as a star. Slice and fry firm young caps with onions for an omelette, add to soups and stews, or dry and grind into a mushroom powder for seasoning.
Easily told from other Leccinum such as the orange birch bolete by its dull brown cap. It has no deadly lookalikes, but as a bolete only ever pick firm specimens, since old soft ones cause stomach upsets, and avoid any bolete with red or orange pores and blue-staining flesh.
County Cavan is classic Irish drumlin country: a maze of low, rounded hills left by retreating glaciers, threaded with hundreds of small lakes (locals say one for every day of the year). The wilder northwest rises towards Cuilcagh Mountain, where the Shannon Pot marks the source of the River Shannon. Mixed woodland clings to the lake shores and hollows between the drumlins, with conifer plantations and broadleaves such as oak, ash, birch and hazel; spots like Killykeen Forest Park around Lough Oughter and the Cuilcagh Burren are good ground. Look for mushrooms among damp leaf litter, on mossy banks and in the boggy fringes where woodland meets wetland.
Cavan has a mild, distinctly damp Atlantic climate with rain spread through the year and few extremes of heat or cold. All that moisture and the lake-laced terrain keep the woods humid, which suits fungi well. Expect a patchwork of small woods, lakeshore margins and drumlin pastures rather than vast forests, so foraging here rewards working many little pockets of habitat. The reliably wet ground gives a long, productive autumn season, with the damp lowland woods often fruiting well after rain.
