When will Slippery Jack appear in County Limerick?

Mushroom season in County Limerick, Ireland is building right now, with slippery jack sitting at 21% today. The typical season runs August to November, and we’re in October now

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.

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.

A decent edible with a mild flavour, good in mixed dishes, soups and sauces rather than as the star. Always peel off the slimy cap skin, which can otherwise cause loose stools, and discard the spongy pore layer on older specimens.

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 Limerick is dominated by the broad, fertile lowland of the Golden Vale that spreads along the River Shannon and the Maigue valley, rimmed to the south and east by the Ballyhoura and Galtee uplands and to the west by the Mullaghareirk hills. The land shifts from rich grazing plains to peaty upland and the tidal flats of the Shannon Estuary. Much of the woodland is Coillte conifer plantation, especially the Sitka spruce of the Ballyhoura forests, alongside pockets of native oak, ash, birch and hazel in river glens and old demesnes. Mushrooms turn up at plantation edges and rides, in mossy broadleaf woods, and out on the limestone grassland and pasture of the lowlands.

Limerick has a mild, damp oceanic climate with cool summers, frost-shy winters and rain spread through the year, the Atlantic keeping things humid. These soft, wet conditions are ideal for fungi, with autumn the prime flush after the September rains. Foragers can expect a generous autumn season, with field species like meadows mushrooms on the Golden Vale pasture and woodland finds such as ceps, chanterelles and hedgehog fungus around the Ballyhoura and Galtee woods. Much of the lowland is farmed and access varies, so the forest parks and upland margins are the most rewarding ground.
