Wild mushrooms run on weather and calendar together; this is a rough Northern-Hemisphere temperate guide — your microclimate shifts everything by weeks, and the Southern Hemisphere offsets by six months. SPRING (Mar–May): morels lead, with oysters, pheasant back / dryad's saddle, and wine cap. SUMMER (Jun–Aug): chanterelles, black trumpets, chicken-of-the-woods, and the first boletes after warm rains. AUTUMN (Sep–Nov): the great flush — porcini / king bolete, hen-of-the-woods (maitake), hedgehog, matsutake, saffron milk cap, blewit, and lobster. WINTER (Dec–Feb): the black truffle peaks, the white truffle finishes from late autumn, and the wild velvet shank (winter enoki) and wood ear persist; cultivated species (shiitake, oyster, enoki, king trumpet, shimeji) are available all year, flat and high. Use this with each species page's hemisphere-aware seasonality scores to plan a hunt or a menu.
