• Genotypic diversity, plant selectivity and community composition of sooty mould symptom forming fungi in a Mata Atlântica relict rainforest
  The collaboration between Fabienne Flessa and Gerhard Rambold has provided valuable insights into the study of epiphytic fungal communities across various ecosystems, with a particular focus on the Brazilian Mata Atlântica. In a comparative study involving samples from the Atlantic Rainforest and Central Europe, they analyzed the composition and diversity of sooty mould communities. The samples from the Mata Atlântica showed significantly higher species richness and included numerous previously undescribed taxa. The study also revealed region-specific fungal assemblages, emphasizing the importance of local environmental conditions in shaping epiphytic microhabitats. This research was complemented by earlier studies focusing on Central European sites. For example, Flessa and Rambold investigated fungal communities on Rhododendron ferrugineum in alpine regions, identifying a dominance of Capnocheirides rhododendri. The results highlighted a high degree of host specificity among phyllosphere fungi. In another study, they examined how the annual leaf fall of deciduous trees in Central Europe influences the development of pigmented epiphytic fungi. Their findings indicated that the limited lifespan of leaves constrains the formation of stable fungal communities, affecting overall diversity. Taken together, these studies provide a comprehensive picture of how climatic, geographic, and host-specific factors shape the structure of epiphytic fungal communities — with the Mata Atlântica emerging as a hotspot of exceptional mycological diversity.

• Studien zur Vergesellschaftung epifoliarer pigmentierter Pilze mit Schwerpunkt in Oberfranken
  The study by Flessa and Rambold compared the communities of dark pigmented epifoliar fungi on deciduous trees around Bayreuth with those on evergreen plants. The results showed no host preference among the fungal taxa, but the community composition differed significantly between annual and perennial leaves, suggesting that the fungal community on deciduous leaves represents an early stage of the same community on evergreen plants.

• Diversity, habitat preferences and ecological adaptations of tropical corticolous lichens in North-East Brazil
  Marcela E. S. Cáceres, Robert Lücking, and Gerhard Rambold have explored the diversity of lichen species in northeastern Brazil. Their work suggests that host tree type, habitat, and microclimate are key factors shaping bark-dwelling lichen communities. They found that deterministic factors like the identity of the host have a larger influence on community structure than random factors. [Details]

Additionally, the study of Usnea samples revealed hidden fungal diversity, emphasizing the need for molecular tools in ecological research. [Details]
  
  
• Substrate specificity of members of the genus Xylaria (Ascomycota)
  Xylaria hypoxylon, the type species of Xylaria, was originally described by Linnaeus and is considered cosmopolitan. However, inconsistent rDNA sequences and morphoanatomical differences indicated a species complex. European populations of X. hypoxylon showed consistent rDNA data, while North American samples matched them. Some non-European strains, however, were identified as X. longiana. [Details]
