Community Analyses Uncover High Diversity of Lichenicolous Fungi in Alpine Habitats

Abstract

Lichens are frequently colonized by specialized, lichenicolous fungi. Symptomatic lichenicolous fungi usually display typical phenotypes and reproductive structures on the lichen hosts. The classification based on these structures revealed different host specificity patterns. Other fungi occur asymptomatically in the lichen thalli and are much less known. We aimed at studying the diversity of lichen-associated fungi in specific, lichen-rich communities on rocks in the Alps. We tested whether lichenicolous fungi developing symptomatically on their known hosts also occur asymptomatically in other thalli of the same or of different host species. We collected lichen thalli according to a uniform sampling design comprising individuals adjacent to thalli that showed symptoms of lichenicolous fungal infections. The total fungal communities in the selected lichen thalli were further studied by single-strand conformation polymorphism (SSCP) fingerprinting analyses and sequencing of internal transcribed spacer (ITS) fragments. The systematic, stratified sampling strategy helped to recover 17 previously undocumented lichenicolous fungi and almost exhaustively the species diversity of symptomatic lichenicolous fungi in the studied region. ...Continue Reading
