The endophyte Allantophomopsis cytisporea is associated with snow blight on Calluna vulgaris in the Alps—An effect of climate change?
Shoots of Calluna vulgaris, Erica carnea, Juniperus communis subsp. nana, Picea abies, and Pinus mugo subsp. mugo covered with felty, melanized epiphytic mycelia typical for brown felt blight caused by Herpotrichia pinetorum were collected at several locations in the Swiss Alps. Most cultures prepar...
