Aproximately 5,000–6,000 fungal species form ectomyorrhizae (ECM), the symbiotic organs with roots of predominantly trees. The contributing fungi are not evenly distributed over the system of fungi. Within Basidiomycota exclusively Hymenomycetes and within Ascomycota exclusively Ascomycetes contribute to the symbiosis. Hymenomycetes play a big part, Ascomycetes a minor role; Zygomycetes only form exceptionally ECM. Responsible for ascomycetous ECM are mostly Pezizales with their hypogeous… 
Scleroderma areolatum ectomycorrhiza on Fagus sylvatica L.
TLDR
A morphological and anatomical description of tree nursery derived ectomycorrhizae of Scleroderma areolatum on Fagus sylvatica, grown for several years in a climatized room is provided and the phylogenetic analysis positioned the newly described ectomyCorrhiza together with Sclerodingma verrucosum and Sclerodma cepa in a single clade with a taxon name SH005470.07FU.
Two sebacinoid ectomycorrhizae on Chinese pine
TLDR
This is the first report of sebacinoid ECM on Chinese pine and the putative molecular phylogenetic relationships of P. multifurcata and P. nondextrinoidea were inferred by analyses of the partial large subunit nuclear rDNA (nLSU); however, an affiliation to fungal species was not possible.
Characterisation and identification of ectomycorrhizae formed by the species of Asproinocybe (Tricholomataceae) and Inocybe (Inocybaceae) with the roots of the tropical sal tree Shorea robusta (Dipterocarpaceae)
TLDR
The morpho-anatomical details of mycorrhizal roots of Shorea robusta associated with Asproinocybe lactifera and Inocybe purpureoflavida are provided for the first time.
How Ectomycorrhizae Structures Boost the Root System
TLDR
Ectomycorrhizal associations increase the root exploration area in soil, boosting the potential for mineral nutrition, water availability, and mutual survival of plant and fungus.
Studies on Ectomycorrhiza: An Appraisal
TLDR
Recent progresses in ectomycorrhizal biology are presented, especially the potential role of ECM symbioses in resistance or tolerance to various biotic and abiotic stresses, and in maintinance of plant diversity for proper ecosystem functioning.
Four ectomycorrhizae of Pyronemataceae (Pezizomycetes) on Chinese Pine (Pinus tabulaeformis): morpho-anatomical and molecular-phylogenetic analyses
TLDR
Morphological and anatomical characters of four ectomycorrhizae with affinities to the genera Humaria, Geopora, and Trichophaea of Pyronemataceae on Chinese Pine and possible taxa affiliations were assessed by molecular-phylogenetic analyses of the internal transcribed spacer (ITS) and partial large subunit (LSU) nrDNA.
Morphological Characteristics of Ectomycorrhizas on Merbau
Merbau [Intsia bijuga (Colebr.) O. Kuntze] is one of valuable timber tree in south-east Asia which has been known having ectomycorrhizae (EcM) though being ignored. Identification of the
Plants and Their Ectomycorrhizosphere: Cost and Benefit of Symbiotic Soil Organisms
TLDR
This work quantifies the exploration type specific space occupation under the influence of twice-ambient ozone concentrations and estimates the carbon cost the tree has to pay for and addresses enzymatic capacities of ectomycorrhizal communities and focus on bacteria being associated with the mycelium.
Ectomycorrhizae associated with Castanopsis fargesii (Fagaceae) in a subtropical forest, China
TLDR
This is the first study to characterize the below-ground ECM communities and anatomical structures in a subtropical evergreen broad-leaved forest of southwest China and identify 17 ECM fungi based on the analysis of ITS sequences.
A sheathing mycorrhiza between the tropical bolete Phlebopus spongiosus and Citrus maxima
TLDR
Although the association between Ph. spongiosus and C. maxima could be considered ectomycorrhizal, its anatomy matches the unique feature known as sheathing mycorrhiza.

Colour Atlas of Ectomycorrhizae
TLDR
The Colour Atlas depicts the habit of ectomycorrhizae as well as the functionally important features of many fungal relationships and of the most important ectomyCorrhizal tree genera and is going to include ectomy CorrhizAE from all over the world.
2 Characterization of Ectomycorrhiza
Evolutionary instability of ectomycorrhizal symbioses in basidiomycetes
TLDR
The results indicate that mycorrhizal symbionts with diverse plant hosts have evolved repeatedly from saprotrophic precursors, but also that there have been multiple reversals to a free-living condition, suggesting that myCorrhizae are unstable, evolutionarily dynamic associations.
ECTOMYCORRHIZA FORMATION BY THE OPERCULATE DISCOMYCETE SPHAEROSPORELLA BRUNNEA (PEZIZALES)
TLDR
The carbonicolous discomycete, Sphaerosporella brunnea, formed ectomycorrhizae with jack pine (Pinus banksiana) in monoxenic cultures and in open containers to determine the degree of host specificity and to develop criteria for the identification of S. brunnea in culture and in the myCorrhizal state.
The ectomycorrhiza Piceirhiza internicrassihyphis: A weak competitor of Cortinarius obtusus?
TLDR
The lack of cystidia and the presence of amyloidy suggest that this ectomycorrhiza Piceirhiza internicrassihyphis is formed by a species of the family Thelephoraceae.
Distance-related semi-quantitative estimation of the extramatrical ectomycorrhizal mycelia of Cortinarius obtusus and Tylospora asterophora
TLDR
It is concluded that these two species differ considerably in the amount and extension of their mycelia and this may be in line with their assignment to the respective exploration types and further studies are needed to substantiate these results.
Structure and ontogeny of Alnus crispa – Alpova diplophloeus ectomycorrhizae
TLDR
Structural changes in the host, the mycosymbiont, and the fungus–epidermis interface were described at various stages in the ontogeny of ectomycorrhizae.
Diversity and abundance of resupinate thelephoroid fungi as ectomycorrhizal symbionts in Swedish boreal forests
TLDR
Tomentelloid fungi appear to be relatively common ectomycorrhizal symbionts with a wide distribution in Swedish coniferous forests, in accordance with accumulating data that fungal species which lack conspicuous sporocarps may be of considerable importance in EM communities.
Identification of Picea-ectomycorrhizae by comparing DNA-sequences

    Mycological Progress
  • 2006
TLDR
Ectomycorrhizae of Picea abies, collected in southwest Germany during several years and described as morphotypes, were identified using LSU and ITS sequences to compare sequences from identified sporocarps.
The new method ‘micromapping’, a means to study species-specific associations and exclusions of ectomycorrhizae
TLDR
The preliminary results suggest that the ECM of Russula ochroleuca and Piceirhiza internicrassihyphis show no common occurrence within short distances, and the method ‘micromapping’ apparently provides a useful tool to analyse spatial relations of ECM in the soil.
