Mushroom crops in relation to weather in the southwestern Yukon
Epigeous mushroom production in the boreal forest ecosystem varies dramatically from year to year. We tested the hypothesis that the aboveground production of epigeous mushrooms in the Kluane region, Yukon, could be predicted by summer rainfall. There is a single crop in this part of the boreal zone...

Epigeous mushroom production in the boreal forest ecosystem varies dramatically from year to year.
