How are Porcini doing in County Longford this September?
Porcini usually come up in County Longford from August to November, and right now they’re at 40% and looking good.
Fruits after warm, humid spells when soil temperatures sit in the mid teens Celsius and a good soaking rain follows a warm period. A typical trigger is heavy rain after several warm days, with flushes appearing roughly one to two weeks later.
Often shares ground with chanterelles, other boletes like the bay bolete, and amanitas including the toxic fly agaric and death cap, so identify everything carefully. The reddish fly agaric under birch and pine is a useful indicator that conditions may suit cep nearby.
Check around the bases of host trees and along sunlit forest edges, returning to productive spots a few days apart through the flush. Cut or twist the stem cleanly, slice each cap to check for maggots, and take only young specimens with white firm flesh.
Can be confused with the bitter bolete (Tylopilus felleus), which has a darker net on the stem, pinkish pores when mature and a strongly bitter taste, and with red pored boletes. Avoid any bolete with red or orange pores or flesh that stains strongly blue.
Longford is a landlocked midland county of gently rolling, low-lying drumlin country, with Corn Hill near Granard its only real high point. Its western edge is dominated by the River Shannon and the broad waters of Lough Ree, and much of the interior is given over to raised bogs, callows and reedy lake margins. Woodland is patchy and small-scale: pockets of broadleaf around demesnes and lakeshores with oak, ash, birch and willow, alongside conifer plantations of spruce and pine. Look for mushrooms in damp mixed woods, along bog edges, in old pasture and among the grassy fringes of the Shannon callows.
The climate is mild, damp and Atlantic, with cool summers, soft winters and rain spread liberally through the year. This steady moisture, combined with the county’s bogs and lakes, keeps the ground reliably humid for fungi well into autumn. Expect a quiet, lowland foraging experience built around bog margins, lakeside woods and grazed fields rather than mountains or coast. Autumn is the main season, with grassland and woodland species the typical finds; much land is private farmland, so seek permission and tread carefully on fragile bog.
