How are Slippery Jack doing in County Waterford this October?

This week’s slippery jack forecast for County Waterford, Ireland reads 14% and just starting.

It fruits after warm late-summer and autumn rain, typically when day temperatures sit around 10 to 20C and the ground stays damp. A good soaking followed by mild nights usually brings flushes within a week or two.

It has a distinct membranous ring or partial veil remnant on the stem, an unusual feature among the slippery-capped Suillus boletes.

Scan the ground near any pine, especially along sandy tracks and clearings where they often appear in groups. Pick young firm caps, since older ones go soft and waterlogged, and carry them separately because the slimy cap coats everything.

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 Waterford rises from a rugged southern coastline into the Comeragh, Monavullagh and Knockmealdown mountains, with the broad valleys of the Blackwater and Suir rivers cutting through fertile lowland in between. The famous Copper Coast gives way inland to corrie lakes, heathery uplands and the secluded Nire Valley. Sheltered river valleys and demesnes hold mixed broadleaf woods of oak, beech, ash and hazel, while conifer plantations of Sitka spruce cloak the lower mountain slopes. Look for fungi along damp woodland edges, in old estate parkland, and in the grassy fields and dunes near the coast.

Waterford has a mild, moist Atlantic climate, often counted among the sunnier corners of Ireland yet still wet enough to keep the ground reliably damp. Frosts are light and rain falls through much of the year, with the uplands catching noticeably more than the sheltered coast. Autumn is the prime season, when mixed woods and old pastures produce ceps, chanterelles and a good range of edible species, and waxcaps colour the unimproved grasslands of the Comeraghs. Much of the best ground sits on private farmland and forestry, so always seek permission and forage carefully.
