This paper describes a novel species of ericoid mycorrhizal fungus from Australia, Cairneyella variabilis, Midgley and Tran-Dinh, gen. nov. sp. nov. The genome of C. variabilis was sequenced and a draft genome assembled. The draft genome of C. variabilis is 52.4 Mbp in length, and to our knowledge, this is the first study to present a genome of an ericoid mycorrhizal fungus from the southern hemisphere. Using the SignalP and dbCAN bioinformatic pipelines, a study of the catabolic potential of C. variabilis was undertaken and showed genes for an array of degradative enzymes, most of which appear to be secreted from the hyphae, to access a suite of different carbon sources. Isolates of C. variabilis have been previously shown to utilise cellulose, carboxymethyl cellulose (CMC), cellobiose, xylan, pectin, starch and tannic acid for growth, and in the current study, putative enzymes for these processes were revealed. These enzymes likely play key roles in nutrient cycling and other edaphic processes in heathland environments. ITS phylogenetic analyses showed C. variabilis to be distinct from the fungi of the "Hymenoscyphus ericae aggregate".

Plant invasions are impacting alpine zones, altering key mutualisms that affect ecosystem functions. Plant-mycorrhizal associations are sensitive to invasion, but previous studies have been limited in the types of mycorrhizas examined. Consequently, little is known about how invaders that host rarer types of mycorrhizas may affect community and ecosystem properties.

Anthropogenically elevated inputs of nitrogen (N), phosphorus (P), and potassium (K) can affect the carbon (C) budget of nutrient-poor peatlands. Fungi are intimately tied to peatland C budgets due to their roles in organic matter decomposition and symbioses with primary producers; however, the influence of fertilization on peatland fungal composition and diversity remains unclear. Here, we examined the effect of fertilization over 10 years on fungal diversity, composition, and functional guilds along an acrotelm (10-20 cm), mesotelm (30-40 cm), and catotelm (60-70 cm) depth gradient at the Mer Bleue bog, Canada.

Mycoviruses with an unprecedented genome organization, featuring the RNA-directed RNA polymerase (RdRp) palm domain coding sequence being split into two distinct genome segments, have been found recently in a few fungi and oomycetes of different lineages and have been proposed to be named "splipalmiviruses". One of these, Oidiodendron maius splipalmivirus 1 (OmSPV1), has been detected in the ericoid mycorrhizal fungus Oidiodendron maius, and it has been proposed to be bisegmented. Here, we complete the genome sequence of this virus by describing a third RNA segment, which is 2000 nt long and whose terminal sequences are identical to those of the other two segments of OmSPV1.

Atmospheric nitrogen (N) deposition has been substantially reduced due to declines in the reactive N emission in major regions of the world. Nevertheless, the impact of reduced N deposition on soil microbial communities and the mechanisms by which they are regulated remain largely unknown. Here, we examined the effects of N addition and cessation of N addition on plant and soil microbial communities through a 17-year field experiment in a temperate grassland.

Article Synopsis
- Archaeorhizomyces is a type of fungi that lives in soil and helps plant roots, but scientists don't know much about it because it's hard to study.
- Researchers found three new types of this fungi on the roots of certain plants in Japan and looked at how they grow and spread.
- They discovered that their new fungi were different enough from known types to describe two new species called Archaeorhizomyces notokirishimae and Archaeorhizomyces ryukyuensis.
