Mazama Mushroom Calendar

Mazama sits in the North Cascades and a drier, rain-shadowed climate, with roughly 23.1 inches of annual rainfall, most of it falling in the cool months from fall into spring. The ground warms and reaches early fruiting potential around April, by which point the average last frost (May 9) has usually passed. Summer fruitings stay confined to pockets of moisture — irrigated urban ground can be one — and the real abundance arrives with the fall rains in October. Winter then shuts the season down hard and early.
