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.
Greyish to dull brown cap up to about 15 cm, with a spongy pore surface underneath that is whitish then greying (not gills). The tall stem is whitish and covered in small dark brown to blackish scales, and the white flesh is soft, barely changing colour when cut.
Use fresh within a day or two as it deteriorates fast and the flesh softens quickly. It dries well into slices or powder, and you can also slice and freeze it after a brief sauté to hold its texture better.
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.
Donegal is the most mountainous county in Ulster, dominated by the quartzite cone of Errigal and the Derryveagh and Blue Stack ranges, with vast blanket bog spread across the uplands. Its deeply indented Atlantic coastline of cliffs, headlands and sandy bays gives way inland to glacial valleys, loughs and rough grazing. Pockets of native oak, birch, hazel and holly survive in places like Glenveagh and the Celtic rainforest of Ardnamona, where mossy ground and damp glens favour fungi. Most woodland, however, is Coillte conifer plantation, chiefly Sitka spruce on upland peat, whose mossy edges and rides are productive ground.
The climate is cool and distinctly wet, shaped by the North Atlantic Drift and prevailing Atlantic westerlies that drive rain in off the ocean year-round. Annual rainfall runs from about 1,000mm on the coast to over 1,500mm in the hills, keeping the ground reliably moist for fungi. Expect a damp, oceanic foraging ground where boggy moor, spruce plantation and the rare native wood each hold their own species, but searching means covering open, exposed terrain. The long, mild autumn extends the season, though weather off the Atlantic can turn quickly.
