The ascomycete class Pezizomycetes (single order Pezizales) is known for its cup‐shaped fruit bodies and the evolution of edible truffles and morels, but little is known about the ontogeny and ecology of this large and ecologically diverse fungal group. In this issue of Molecular Ecology, Healy et al. ( ) make a great leap forward by describing and identifying asexual, anamorphic structures that produce mitotic spores in many ectomycorrhiza‐forming truffle and nontruffle species on soil… 

Topics from this paper

Ploidy-specific symbiotic interactions: divergence of mycorrhizal fungi between cytotypes of the Gymnadenia conopsea group (Orchidaceae).
TLDR
This study provides the first evidence that polyploidization of a plant species can be associated with a shift in mycorrhizal symbionts, and this divergence may contribute to niche partitioning and facilitate establishment and co-existence of different cytotypes.
In Vitro Observations of the Interactions between Pholiota carbonaria and Polytrichum commune and Its Potential Environmental Relevance
TLDR
Physical interactions between a post-fire fungus, Pholiota carbonaria, and a moss, Polytrichum commune, were visually examined under laboratory conditions and provided the first visual documentation of these structures in vitro.
Rescuing the ectomycorrhizal biodiversity associated with South American Nothofagaceae forest, from the 19th century naturalists up to molecular biogeography
The southernmost portion of the Andes in South America hosts Nothofagaceae forests that form ectomycorrhizal (EcM) associations. We compiled all the published reports of EcM taxa from these
Diversity of fungal endophytes in the semi evergreen vine thickets of the southern Brigalow Belt bioregion and their production of antimicrobial secondary metabolites.
TLDR
The results of this study indicate that Semi-evergreen vine thickets (SEVT) harbour a vast storehouse of novel and medicinally significant endophytic fungi.
Draft Root-associated fungi of Pinus wallichiana A . B . Jackson in Kashmir Himalaya
9 An important factor in the performance of out-planted conifers is the association of plant roots with 10 ectomycorrhizal (EcM) fungi. However, limited information is available about the diversity
Temporal variation in mycorrhizal diversity and carbon and nitrogen stable isotope abundance in the wintergreen meadow orchid Anacamptis morio.
TLDR
Observations suggest that, irrespective of differences in the seasonal environmental conditions, the plant phenological stages and the associated fungi, the isotopic content in mycorrhizal A. morio remains fairly constant over time.
Recent Changes in Fungal Nomenclature and Their Impact on Naming of Microfungi
TLDR
To provide for some stability, provisions are introduced for the preparation of lists of protected/suppressed names, in which deviation from temporal priority is possible when leading to meaningful generic circumscription and following established usage; names on these lists will subsequently be regarded as conserved/suppression.

Molecular and morphological diversity of pezizalean ectomycorrhiza.
TLDR
It is demonstrated that Pezizales species constitute a considerable proportion of the mycobionts in EcM fungal communities in mature boreal deciduous and coniferous forests, in several soil types.
Ascomycetes associated with ectomycorrhizas: molecular diversity and ecology with particular reference to the Helotiales.
TLDR
A high diversity of these fungi on different hosts and habitats is demonstrated and the ubiquity and diversity of the secondary root-associated fungi should be considered in studies of mycorrhizal communities to avoid overestimating the richness of true symbionts.
Biotrophic associations between lodgepole pine seedlings and postfire ascomycetes (Pezizales) in monoxenic culture
TLDR
Twenty-two species of postfire ascomycetes belonging to the order Pezizales were screened for biotrophic interactions with roots of lodgepole pine, and the only confirmed mutualistic species was Sphaerosporella brunnea, which formed ectendomycorrhizae.
High diversity and widespread occurrence of mitotic spore mats in ectomycorrhizal Pezizales
TLDR
The broad geographic range, high frequency and phylogenetic diversity of spore mats produced by EcM Pezizales suggests that a mitospore stage is important for many species in this group in terms of mating, reproduction and/or dispersal.
A phylogenetic estimation of trophic transition networks for ascomycetous fungi: are lichens cradles of symbiotrophic fungal diversification?
TLDR
Use of phylogenetic analyses that incorporate these newly recovered fungi and ancestral state reconstructions that take into account phylogenetic uncertainty provide the basis for estimating trophic transition networks in the Ascomycota and provide a first set of hypotheses regarding the evolution of symbiotrophy and saprotrophy in the most species-rich fungal phylum.
Community Analysis Reveals Close Affinities Between Endophytic and Endolichenic Fungi in Mosses and Lichens
TLDR
This study reveals the distinctiveness of endolichenic communities relative to those in living and dead plant tissues, with one notable exception: it is found that fungal communities differ at a broad taxonomic level as a function of the phylogenetic placement of their plant or lichen hosts.
Host and geographic structure of endophytic and endolichenic fungi at a continental scale.
TLDR
This study provides a first evaluation of endophytic and endolichenic fungal associations with their hosts at a continental scale and sets the stage for empirical assessments of ecological specificity, metabolic capability, and comparative genomics.
Differential hypogeous sporocarp production from Nothofagus dombeyi and N. pumilio forests in southern Argentina
TLDR
This work examined the spring and autumn community composition of “sequestrate fungi”, based on sporocarp production in pure forests of Nothofagus dombeyi (evergreen) and N. pumilio (deciduous) and found that two different forest stands, each dominated by different species of Nothsofagus, exhibited different hypogeous sporocaru communities.
