Morphology, anatomy, and molecular studies of the ectomycorrhiza formed axenically by the fungus Sistotrema sp. (Basidiomycota)
This is the first report proving in axenic culture that a fungus belonging to the genus Sistotrema forms true ectomycorrhizal status, and it is believed that this species is polyphyletic.
Characterization of Ectomycorrhizal species through molecular biology
Mycorrhizae are mutualistic associations between fungi and plant roots. These symbiotic associations are abundant and occur in 75 to 80 % of plants. Ectomycorrhizal fungi are very important in
Fungal relationships and structural identity of their ectomycorrhizae
A limited number of species could be considered, some general conclusions are possible and the most important ectomycorrhizal relationships within Hymenomycetes and within Ascomycota contribute to the symbiosis.
Sistotrema is a genus with ectomycorrhizal species − confirmation of what sequence studies already suggested
The ectomycorrhizal status of Sistotrema sp. is shown by morphological–anatomical and molecular identification, confirming earlier reports about Sistotrema DNA in ectomycorrhizae (ECM). For molecular
Characterization of Ectomycorrhizal species through molecular biology tools and morphotyping
The objective of this study was to show that the use of molecular biology tools associated with morphotyping to characterize species of ectomycorrhizae is more effective than when they are used on their own.
Two sebacinoid ectomycorrhizae on Chinese pine
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.
Scleroderma areolatum ectomycorrhiza on Fagus sylvatica L.
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.
The AD-type ectomycorrhizas, one of the most common morphotypes present in truffle fields, result from fungi belonging to the Trichophaea woolhopeia species complex
It is shown that AD-type ECMs result from host plant colonization by the pyronemataceous species Trichophaea woolhopeia, and the 28S and internal transcribed spacer (ITS) rDNA regions are analyzed to sustain the hypothesis that T. woolh hopeia is a species complex.
Basal hymenomycetes belonging to the Sebacinaceae are ectomycorrhizal on temperate deciduous trees.
Two sebacinoids of divergent rDNA sequences were demonstrated to form similar ectomycorrhizas, with a well-developed Hartig net and a hyphal mantle having thick-walled outer mantle hyphae.
Ectomycorrhizas involving sebacinoid mycobionts.
Observations on ectomycorrhizas and basidiomes suggest that species of Sebacinaceae are fairly common mycobionts in various ectomyCorrhizal plant communities and the complex trophic relationships in the SebacInaceae are discussed.


Selection of Fungi for Ectomycorrhizal Inoculation in Nurseries
In co-evolving with their host plants, the mycorrhizal fungi have developed impressive physiological and ecological diversity.
Structure and ontogeny of Alnus crispa – Alpova diplophloeus ectomycorrhizae
Structural changes in the host, the mycosymbiont, and the fungus–epidermis interface were described at various stages in the ontogeny of ectomycorrhizae.
Synthesis of Elaphomyces muricatus + Pinus sylvestris ectomycorrhizae
Ectomycorrhizal morphology, mantle anatomy, and cultural characteristics of E. muricatus were examined in view of the possible relationship to Cenococcum geophilum and agreed in all respects with ectomy Corrhizae associated with E. Muricatus ascocarps.
Structure and function of mycorrhizal rhizomorphs with special reference to their role in water transport
Anastomosing systems of fungal rhizomorphs are found in association with mycorrhizal roots of trees in arid zones1, in soils of temperate deciduous2, coniferous3 and humid tropical4 forests, and even
Synthesized ectomycorrhizae of aspen: fungal genus level of structural characterization
The ability of Populus tremuloides Michx. to form ectomycorrhizae with identified species of fungi was investigated using a pouch technique. Twenty-nine out of 54 fungus species formed
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.
SUMMARY The ability of two shrubby alders to form ectomycorrhizae with known species of fungus was investigated. Frankia- inoculated seedlings of Alnus crispa and Alnus rugosa were raised in growth
Ascomycete mycorrhizas from pot-grown silver-fir seedlings (Abies alba Mill.).
Ulastructural investigations showed that the dolipore seemed to be the main distinguishing feature between ascomycete and basidiomycete mycorrhizas, and differences in the matrix of the interface and the fungal wall were not stable enough to be used as a distinguishingfeature between asco- and basidiaomycetes.
Characterization and classification of mycorrhizae of Douglas fir. II. Pseudotsuga menziesii + Rhizopogon vinicolor
A common tuberculate ectomycorrhiza of Douglas fir in the Pacific Northwest, described earlier by Trappe, is further examined and defined. Tubercles consist of an outer rind of aseptate, amber,
Taxonomic affinities and criteria for identification of the common ectendomycorrhizal symbiont of pines
Evidence from cultured and soil-borne mycelium clearly indicates that the widespread mycorrhizal symbiont (or symbionts) known as the E-strain is an ascomycete anamorph. The evidence includes regular
