Fruits in late summer and autumn after warm spells broken by steady rain, typically when daytime temperatures sit around 12 to 20 C. A few days of moisture following a warm period usually triggers a flush.
Grows on the ground in grassy, open places such as pasture, meadows, road verges, woodland edges and clearings, often on poor or sandy soil. It favours sunny spots and is not tied to a particular tree.
A prized edible with a mild, slightly nutty taste. The caps are good dusted in flour or breadcrumbs and fried whole like a schnitzel; the fibrous stems are usually too tough to eat and are discarded.
Can be confused with members of the genus Chlorophyllum, especially Chlorophyllum brunneum and the American Chlorophyllum molybdites, which cause stomach upsets. The parasol is told apart by its tall snakeskin-patterned stem, a movable double-edged ring and flesh that does not turn red when cut; the dangerous lookalikes are stockier with a bulbous stem base and often bruise reddish. Avoid any small Lepiota species, several of which are deadly poisonous.
Isère runs from the flat Rhône valley plains and the Bièvre lowlands in the west to the limestone massifs of the Vercors and Chartreuse and the crystalline peaks of Belledonne and the Écrins in the east. The Isère river carves the broad Grésivaudan valley past Grenoble, where basins meet steep slopes rising above 4,000 metres. Beech and silver fir cloak the Vercors and Chartreuse plateaux on limestone, mixed with spruce higher up, while oak, chestnut and pine hold the warmer lower slopes and the Terres Froides. This range of soils and altitudes, from calcareous ridges to acidic crystalline massifs, gives fungi a long succession of habitats.
Grenoble’s sheltered basins bring hot summers, cold winters and marked temperature inversions, while rainfall climbs steadily with altitude across the massifs. Damp, cooling autumns after summer storms trigger the main flush, and the spring thaw feeds the morel season on the valley floors. Autumn is the peak, when the beech-fir forests of the Vercors and Chartreuse yield ceps and porcini, chanterelles and black trumpets on the leaf litter. Spring brings morels to the alluvial woods and poplar stands of the Isère and Drac valleys, while lower oak and chestnut woods add further boletes.
