Within the framework of the JGI CSP project  'Metatranscriptomics of Forest Soil Ecosystems', we are aiming to explore the interaction of trees with communities of soil fungi, including ectomycorrhizal symbionts that dramatically affect plant growth, and saprotrophic soil fungi impacting carbon sequestration in forests. We are sequencing the genomes of the most abundant fungal species harvested on several long-term observatories in boreal, temperate and mediterranean woodlands to serve as the foundation for a reference database for metagenomics and metatranscriptomics of fungi, and for a comprehensive survey of the potential soil fungal metabolome.

Mycena galopus

M. galopus, commonly known as the milking bonnet or the milk-drop Mycena, is a basidiomycete in the Mycenaceae family of the Agaricales order. This woodland mushroom is very commonly found on debris of various deciduous trees as well as on fallen needles of coniferous trees. M. galopus is among the most important leaf litter decomposers in coniferous and angiosperm forests, having the potential to utilise all the major constituents of plant litter. This saprotrophic fungus is able to efficiently decay the lignocellulose of leaf litter, but it is also able to degrade hemicelluloses, proteins, xyloglucans and pectins by using secreted enzymes. In addition, M. galopus mycelium can increase the availability of phosphorus and other nutrients, both as a result of soil acidification and via the release of weathering agents such as organic acids. The sequenced strain, ATCC-62051, was provided by Hibbett's lab at Clark University.

The genomes of other litter decayers, such as Gymnopus luxurians and G. androsaceus, have also been sequenced by the JGI allowing in-depth comparison of the decay mechanisms in this guild of forest litter decayers.
