The complete mitochondrial genomes of five lichenized fungi in the genus Usnea (Ascomycota: Parmeliaceae).

ABSTRACT: Known colloquially as 'Old Man's Beard', Usnea is a genus of lichenized Ascomycete fungi characterized by having a fruticose growth form and cartilaginous central axis. The complete mitochondrial genomes of Usnea halei, U. mutabilis, U. subfusca, U. subgracilis, and U. subscabrosa were sequenced using Illumina data and then assembled de novo. These mitogenomes ranged in size from 52,486 bp (U. subfusca) to 94,464 bp (U. subgracilis). All were characterized by having high levels of intronic and intergenic variation, such as ORFs that encode proteins with homology to two homing endonuclease types, LAGLIDADG and GIY-YIG. Genes annotated within these mitogenomes include 14 protein-coding genes, the large and small ribosomal subunit
