McDonald, T./ E. Gaya/ F. Lutzoni 2013: Twenty-five cultures of lichenizing fungi available for experimental studies on symbiotic systems. - Symbiosis59(3): 165-171. [RLL List # 230 / Rec.# 34374] Abstract: In this study we describe the techniques used to culture 25 mycobionts spanning three classes and five orders of the leotiomyceta (Ascomycota). We find that five media, including potato-carrot, malt extract-yeast extract (MY), Bold’s basal medium with nitrogen (NMBBM), oatmeal, and yeast extract with supplements (YES), are sufficient to induce ascospore germination of many lichenizing fungi and are also suitable for maintaining growth of the culture over the long term. Regular physical disruption of the cultures in liquid media is recommended to stimulate continued growth. Genomes of five of these lichen-forming fungal strains have been sequenced. The identity of each culture was confirmed by sequencing the nuclear ribosomal internal transcribed spacer (ITS) or the mitochondrial small subunit (mitSSU) from each strain. Additionally, the level of sequencing in terms of total number of genes sequenced for each taxon is provided. All fungal cultures have been deposited in public culture collections and, therefore, are available to the scientific community for conducting in vitro experiments.
