## TL;DR

This paper provides a high-quality genome sequence of the lichen-forming fungus Lecanora helva from a tropical mangrove in Thailand.

## Contribution

The study introduces a novel multi-assembler approach to generate a nearly complete genome sequence of Lecanora helva.

## Key findings

- The genome assembly is 30.07 Mb with 98.1% BUSCO completeness.
- The sequencing was done using PacBio HiFi technology.
- The genome will support research on mangrove adaptation and climate resilience.

## Abstract

We present a high-quality genome assembly of the lichenized fungus Lecanora helva collected in a tropical mangrove in Thailand. Using PacBio HiFi sequencing and a novel multi-assembler approach, we generated a contiguous, nearly complete (30.07 Mb, 98.1% BUSCO completeness) genome sequence, enabling future studies on mangrove adaptation and climate resilience.
