Last autumn a great drift of spores ofChrysomyra woroniniiwas found in Kebnckaise, the highest mountains in Sweden. The author has correlated it with the strong infection of the same parasitic fungus on thePiceain the forests of Norrland. An examination of the meteorological situations in the latter part of August indicates that the spore drift with the wind occurred on August 27–28. As the spores must have flown at least 75 km, this little paper is of interest in our studies of the long-distance transport problem in pollen analysis.
