Suddenly, he stops and begins to dig furiously with both paws. “Ah, he’s found an Italian white truffle,” Mirko explains. “He uses both paws only when he fin...
Recent surveys of belowground fungal biodiversity in México and USA have revealed many undescribed truffle species, including many in the genus Tuber. Here we describe seven new species: Tuber beyerlei, T. castilloi, T. guevarai, T. lauryi, T. mexiusanum, T. miquihuanense and T. walkeri. Phylogenetic analyses place these species within the Maculatum group, an understudied clade of small truffle...
roots of helianthemum species were collected from various rangeland sites in fars, and other provinces in iran. the partial small subunits of ribosomal dna genes were amplified with the genomic dna extracted from their roots by nested polymerase chain reaction (pcr) using the universal fungal primer pair its1/its4 and specific primer pair ftc/rtc, which was designed based on internal transcribe...
Truffles ascocarps need carbon to grow, but it is not known whether this carbon comes directly from the tree (heterotrophy) or from soil organic matter (saprotrophy). The objective of this work was to investigate the heterotrophic side of the ascocarp nutrition by assessing the allocation of carbon by the host to Tuber melanosporum mycorrhizas and ascocarps. In 2010, a single hazel tree selecte...
