Summary
Background
Epiphytic fungi have evolved multiple times within Dothideomycetes, particularly in orders like Asterinales, Capnodiales, Microthyriales, and Zeloasperisporiales. The order Neodactylariales is poorly known and was originally circumscribed based only on the genus Neodactylaria. Recent discoveries of related genera necessitate taxonomic revision and emendation of this order and family.
Objective
To describe a new fungal genus and species isolated from sooty mould communities on Symphoricarpos albus leaves in Poland and to provide phylogenetic analysis and emended descriptions of the order Neodactylariales and family Neodactylariaceae based on morphological and molecular data.
Results
Szaferohypha enigmatica, a new monotypic genus and species, was isolated and assigned to Neodactylariales based on phylogenetic placement. The genus differs morphologically from related genera Beaucarneamyces, Neodactylaria, and Pseudoarthrographis. Neodactylariales formed a well-supported clade (MLB = 85%) that showed a strongly supported sister relationship to Oncopodiellales.
Conclusion
The discovery of Szaferohypha necessitated emendation of the order Neodactylariales and family Neodactylariaceae to include characters of all four genera now placed within this group. Sooty mould communities represent an underexplored source of rare fungal species, particularly in temperate regions.
