When will Slippery Jack appear in County Roscommon?
Mushroom season in County Roscommon, Ireland is just starting right now, with slippery jack sitting at 3% 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.
It has a distinct membranous ring or partial veil remnant on the stem, an unusual feature among the slippery-capped Suillus boletes.
Always peel off the slimy cap skin and remove the spongy pore layer first, as both can upset the stomach. Slice and fry in butter for a soft side dish, add to risotto or stews where the texture suits, or dry the cleaned pieces and grind into a savoury mushroom powder for stocks and sauces.
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.
Roscommon is a landlocked county of gentle limestone lowlands, drumlin hummocks and broad river plains, with no coast and few real hills. Much of it lies between the River Shannon to the west and the River Suck to the east, threaded with raised bogs, fens, callows and seasonal turlough lakes. Woodland is patchy but rich, ranging from mixed estate forests like Lough Key to scattered stands of oak, ash, birch and hazel alongside Coillte conifer plantations. The most productive ground for fungi is the damp broadleaf woodland, bog margins and old parkland, plus the grassy callows and pastures that fruit with field species.
The climate is mild, humid and distinctly oceanic, with rain spread generously across the year and few weather extremes. Frequent damp spells over the bogs and river meadows keep the soil moist, which suits fungi well from late summer into autumn. Expect a quiet, low-key foraging county where wetland edges, bog fringes and limestone pastures matter as much as the woods themselves. Autumn after rain is the reliable window, with grassland and woodland species both worth seeking once the ground stays damp.
