Key Points

To assemble and characterize the haploid genome of Lichina pygmaea and analyze its associated microbial metagenomes.
Conducted genome assembly of Lichina pygmaea.
Scaffolded genome into 7 chromosomal pseudomolecules.
Annotated genes using Ensembl.
Recovered microbial metagenomic data to identify MAGs.
Generated a haploid genome of 32.42 megabases in length.
Identified 8,665 protein-coding genes within the genome.
Recovered 9 metagenomic bins, including 4 high-quality MAGs.

Abstract

We present a haploid genome assembly from an individual Lichina pygmaea (Black Lichen; Ascomycota; Lichinomycetes; Lichinales; Lichinaceae). The genome sequence has a total length of 32.42 megabases. The assembly is scaffolded into 7 chromosomal pseudomolecules. The mitochondrial genome has also been assembled, with a length of 47.95 kilobases. Gene annotation of this assembly on Ensembl identified 8 665 protein-coding genes. From the metagenome data, we recovered 9 bins, of which 4 were high-quality MAGs.
