Summary: Chaetosphaeriaceae sp. FL1790
Chaetosphaeriaceae sp. FL1790 was isolated from a decomposing
needle of Pinus clausa at Archbold Biological Station,
Florida as part of a study examining endophytic and saprotrophic
fungal communities across North America (U’Ren & Arnold,
2016). We identified this isolate as an unidentified species of
Chaetosphaeriaceae (Pezizomycotina, Sordariomycetes,
Chaetosphaeriales) using ITS-partial LSU rDNA sequencing. Based on
ITS rDNA sequence similarity, we determined that fungi with this
genotype also occur as endophytic fungi in living photosynthetic
tissues. Described species of Chaetosphaeriaceae occur worldwide in
both temperate and tropical climates and are typically saprobes of
decaying wood and decomposed plant substrates (Fernández et
al., 2006; Cannon & Kirk, 2007). Comparative genomic analyses
of FL1790 will provide an important framework for understanding the
evolution of ecological modes and substrate use in the
Sordariomycetes.
