dc.description.abstract
Biogenic ice nucleation (IN) in the atmosphere is a topic of growing interest, as, according to IPCC, the impact of
IN on global climate is crucial to perform reliable climate model calculations. About 20 years ago IN activity of a
few lichen and Fusarium species [1,2] was reported, while all other investigated fungi were IN-negative. However,
as the fungal kingdom is vast, many abundant species, especially the Basidiomycota (most mushrooms), were not
tested before. Furthermore, the focus of the past studies was on the IN activity of the mycelium as a cryoprotective
mechanism, and not on the airborne spores.
We carried out oil immersion measurements [3] with spores from 17 different fungal species of ecological,
economical or sanitary importance. Most of these species have not been investigated before, like exponents of
Aspergillus, Trichoderma and Agaricales (most mushrooms). Apart from F. avenaceum, spores of all measured
species showed moderate or no IN activity, supporting the hypothesis that significant IN activity is a rather
exclusive property of only a few species within the fungal kingdom.
