Graduate Student Opportunities
Fungal diversity and ecology, including plant-fungal, fungal-invertebrate, and fungal-microbial interactions; fungal systematics and phylogeny; fungal diversity and conservation
Seeking MSc and PhD students (dependent on funding) to start May/September 2018 on projects related to molecular systematics of Arctic agarics, with European collaborators who are compiling a morphology-based manual of Eurasian basidiomycetes that will contain keys, descriptions and illustrations to the species
