Intercontinental divergence in the Populus-associated ectomycorrhizal fungus, Tricholoma populinum.

Phylogeographic structure was not observed within Scandinavian or North American lineages of T. populinum, and intercontinental divergence appears to have resulted from either allopatric isolation; a recent, rare long-distance dispersal founding event followed by genetic drift; or the response in an obligate mycorrhizal fungus with a narrow host range to contractions and expansion of host distribution during glacial and interglacial episodes within continents.

Ectomycorrhizal fungi in Mexican Alnus forests support the host co-migration hypothesis and continental-scale patterns in phylogeography

Alnus-associated ECM assemblages have clear patterns in richness and composition across a wide range of geographic locations, supporting the host–ECM fungi co-migration hypothesis from a common north temperate origin.

Inter- and Intra-Continental Genetic Variation in the Generalist Conifer Wood Saprobic Fungus Phlebiopsis gigantea

The genetic differentiation identified here among P. gigantea individuals from coniferous forests from different world regions indicates that European isolates of this fungus should not be used in North America (or vice versa), and, likewise, commercially available eastern North American P. gigsantea isolates should not been used in western North America forests.

Phylogeographic Analyses of a Boreal-Temperate Ectomycorrhizal Basidiomycete, Amanita Muscaria, Suggest Forest Refugia in Alaska During the Last Glacial Maximum

DNA sequence data from Amanita muscaria is analysed using phylogenetic and coalescent methods to test whether this boreal-temperate ectomycorrhizal fungus was present in Alaska during the Last Glacial Maximum and indicates that there are at least two endemic groups showing no detectable migration from or to populations that survived the LGM in Southern refugia.

Multilocus phylogenetic analyses reveal unexpected abundant diversity and significant disjunct distribution pattern of the Hedgehog Mushrooms (Hydnum L.)

This study extensively gathered specimens of Hydnum from Asia, Europe, America and Australasia, and analyzed them by using sequences of four gene fragments, recognizing at least 31 phylogenetic species within Hydnum, 15 of which were reported for the first time.

Genetic variation within the cosmopolitan aquatic fungus Lignincola laevis (Microascales, Ascomycota)

The high genetic divergence suggests that Lignincola laevis is a species complex that consists of a group of closely related species with subtle morphological differences, and the lack of geographical structure in the sampled isolates of L. Laevis may suggest a high dispersal capacity for the cosmopolitan aquatic fungus.



Molecular phylogeny and biogeography of the widely distributed Amanita species, A. muscaria and A. pantherina.

The molecular phylogeny and biogeography of two widely distributed Amanita species, A. muscaria and A. pantherina, were studied based on specimens from diverse localities and revealed a greater divergence of the beta-tubulin region than the ITS region.

Beringian origins and cryptic speciation events in the fly agaric (Amanita muscaria)

The data suggest that populations of A. muscaria later evolved into species, expanded their range in North America and Eurasia, and adapted to the cooling climate.

Genet size and distribution of Amanita muscaria in a suburban park, Dunedin, New Zealand

The presence of both small and large genets (or widely separated ramets) indicates that establishment through sexually derived basidiospores and through mycelial spread may play important roles in populations of A. muscaria such as the one studied.

Molecular phylogenetic analysis of Grifola frondosa (maitake) reveals a species partition separating eastern North American and Asian isolates

A phylogenetic analysis was performed on 51 isolates of the commercially valuable basidiomycete, Grifola frondosa, using sequences from the Internal Transcribed Spacers and 5.8S region of the nuclear ribosomal DNA (rDNA) and a portion of the β-tubulin gene, showing strong support for a species partition separating eastern North American and Asian isolates.

Mycorrhizas: Symbiotic Mediators of Rhizosphere and Ecosystem Processes

Molecular Evolution and Phylogenetics

This work will formulate this biological problem in computational terms by studying two probabilistic models of divergence: Jukes-Cantor & Kimura, and would like to detect evidence of natural selection in populations.

Eukaryotic microbes, species recognition and the geographic limits of species: examples from the kingdom Fungi

It is shown that inferred geographic range of a fungal species depends upon the method of species recognition and that microbial organisms generally have fewer morphological characters, and that the rate of morphological change will be slower for organisms with less elaborate development and fewer cells.

Mycorrhizas and nutrient cycling in ecosystems - a journey towards relevance?

The results support the hypothesis that selection has favoured ericoid and ectomycorrhizal systems with well developed saprotrophic capabilities in those ecosystems characterized by retention of N and P as organic complexes in the soil.

A randomization test for phylogenetic information in systematic data

-A randomization procedure is proposed to determine if sets of data used for phylogenetic analysis contain phylogenetically nonrandom information. The method compares the observed number of steps on
