In the same pine woods and season look for other Suillus such as larch bolete and weeping bolete, plus saffron milkcaps and the occasional bay bolete or porcini on richer patches. False chanterelles and various brittlegills often share the same acidic ground.
Use fresh within a day or two as the slime makes it perish quickly; peel and clean before chilling. It dries well once peeled and de-pored, and the dried slices or powder keep for months in an airtight jar; it can also be cooked and then frozen.
Other Suillus boletes such as the larch bolete (Suillus grevillei) and weeping bolete, all of which are also edible, so there are no dangerous poisonous lookalikes. The slimy brown cap, yellow pores and ringed stem set it apart from any toxic gilled mushroom.
County Galway splits in two: the wild, mountainous and bog-strewn west of Connemara with the quartzite peaks of the Twelve Bens and Maumturks, and the flat limestone plains of the east, divided by Lough Corrib, Ireland’s second-largest lake. The long Atlantic coastline of bays, inlets and exposed headlands frames the whole county. Native sessile oak woodlands cling to sheltered valleys, alongside birch and hazel scrub on the limestone, with stands of ash and the well-known native woods at Coole Park near Gort. Large Sitka spruce plantations cover much of Connemara, and their mossy floors and forest edges are prime fungal ground.
This is one of the mildest and wettest corners of Ireland, with a strong oceanic Atlantic influence bringing frequent rain, high humidity and few hard frosts. Damp, mild autumns keep the soil moist well into the season, ideal for steady fungal fruiting. Expect generous pickings in the oak and birch woods and along conifer plantation edges, while the vast Connemara bogs and acid heaths offer their own specialist species. Wet ground and rough terrain are part of the experience, so sturdy boots and respect for private and grazing land go a long way.
