The whole genome was approximately 44.63 Mb, with a GC content of 40.69%. Genome assembly generated 207 scaffolds with an N50 length of 563,100 bp, N90 length of 122,672 bp. The genome comprised 9,581 genes, some encoded enzymes

Lecanora neobarkmaniana (Lecanorales, Lecanoraceae), A New Lichen Species from South Korea Mycobiology (IF 1.9) Pub Date : 2023-02-06 Jung Shin Park, Sang-Kuk Han, Soon-Ok Oh
Abstract Lecanora is one of the largest genera of lichens worldwide. These lichens can be easily seen, and are commonly found on trees and rocks. Most Korean Lecanora species belong to the Lecanora subfusca group, which has well-defined superficial thallus, red–brown apothecia, and soredia. The new species of L. neobarkmaniana grows on rocks, farinose soredia coalescing, usually covering the whole
