Differential hypogeous sporocarp production from Nothofagus dombeyi and N. pumilio forests in southern Argentina

open access: yesMycologia, 2012
Mycorrhizal fungi that form hypogeous sporocarps are an important component of the temperate forest soil community. In many regions, such as the Nothofagus forest in the Patagonian Andes, this group of fungi has been poorly studied. Here we examined the spring and autumn community composition of "sequestrate fungi", based on sporocarp production in ...
