Taxonomic annotation of public fungal ITS sequences from the built environment - a report from an April 10-11, 2017 workshop (Aberdeen, UK).

Recent DNA-based studies have shown that the built environment is surprisingly rich in fungi. These indoor fungi - whether transient visitors or more persistent residents - may hold clues to the rising levels of human allergies and other medical and building-related health problems observed globally. The taxonomic identity of these fungi is crucial in such pursuits.

and related synnematous fungi with notes on species from the built environment.

A recent taxonomic revision of with an emphasis on synnematous fungi enabled re-identification of previously isolated indoor strains of . All available strains from the culture collection of the Westerdijk Institute were studied, 20 originating from the built environment. Phylogenetic relationships were inferred from DNA sequence data from the internal transcribed spacer 1 and 2 and intervening 5.

revisited.

In 2007 a new leaf spot disease of (sugar beet) spread through the Netherlands. Attempts to identify this destructive sp. in sugar beet led to a phylogenetic revision of the genus.

and scopulariopsis-like species from indoor environments.

Scopulariopsis-like species are often reported from the indoor environment, as well as from clinical samples. The lack of type isolates and thorough phylogenetic studies in the hampered the correct identification of these isolates. Based on recent phylogenetic studies, which resulted in multiple name changes, the aim is to molecularly identify the and scopulariopsis-like species which occur in the indoor environment and give an overview of the current species in these genera and their habitats.
