When will Slippery Jack appear in County Kildare?

This week’s slippery jack forecast for County Kildare, Ireland reads 30% and building.

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 Kildare is a landlocked, low-lying county in Ireland’s eastern central plain, with few hills beyond the eastern fringe where the land begins to rise towards the Wicklow Mountains. Its character is defined by flat farmland, the open grassland of the Curragh, and the vast raised peatlands of the Bog of Allen. Native woodland is limited, but you’ll find mixed broadleaf stands of oak, ash, beech and birch along the Liffey and Barrow river valleys and in demesne woods, alongside conifer plantations of spruce and pine. Grassy pastures, old parkland, the bog margins and damp riverside meadows are the most productive ground for fungi.

Kildare has a mild, damp temperate climate with rain spread fairly evenly through the year and no extremes of heat or cold. Being inland it is slightly drier than the west coast, but the autumn stays humid and moist, which suits mushroom growth. Expect open, accessible country rather than deep forest, with finds concentrated in pasture, parkland, canal banks and the scattered woods rather than across wide tracts of trees. Autumn is the main season, and much of the land is farmed or used for horses, so always seek permission and stick to public ground and rights of way.
