Teichospora sp. FL1471 was isolated in culture from surface-sterilized, decomposing leaf litter of saw palmetto, Serenoa repens (Arecaceae), at Archbold Biological Station, Florida as part of a study examining endophytic fungal communities across North America (U’Ren et al., 2012; U'Ren and Arnold, 2016). We classified this isolate as an unidentified species of Teichospora (Pezizomycotina, Dothideomycetes, Pleosporales, Teichosporaceae) via ITS-partial LSU rDNA sequencing. Described species of Teichospora primarily occur as saprotrophs of wood and bark in temperate forests, although some species inhabit senescent leaves and inflorescences (Kohlmeyer and Volkmann-Kohlmeyer 2000; Marincowitz et al. 2008; Crous et al. 2015). Based on ITS rDNA sequence similarity, we determined that fungi with this genotype also occur as endophytic fungi in living leaves. Comparative genomic analyses of FL1471 will provide an important framework for understanding the evolution of ecological modes, substrate use, and plant cell wall degradation in this diverse clade.
