sp. nov. (, ): a paleoendemic species of section discovered in Japan.

A previously unknown morel species apparently endemic to Japan is here described. is proposed for this species. This new taxon displays archaic features recalling section (pileus lanceolate, few primary alveoli), and a yellow pileus similar to subsection of section .

New insights into black truffle biology: discovery of the potential connecting structure between a Tuber aestivum ascocarp and its host root.

According to isotopic labeling experiments, most of the carbon used by truffle (Tuber sp.) fruiting bodies to develop underground is provided by host trees, suggesting that trees and truffles are physically connected. However, such physical link between trees and truffle fruiting bodies has never been observed.

True morels (Morchella, Pezizales) of Europe and North America: evolutionary relationships inferred from multilocus data and a unified taxonomy.

Applying early names, with or without original material, to genealogical species is challenging. For morels this task is especially difficult because of high morphological stasis and high plasticity of apothecium color and shape. Here we propose a nomenclatural revision of true morels (Morchella, Pezizales) from Europe and North America, based on molecular phylogenetic analyses of portions of the genes for RNA polymerase II largest subunit (RPB1) and second largest subunit (RPB2), translation elongation factor-1α (TEF1), the nuc rDNA region encompassing the internal transcribed spacers 1 and 2, along with the 5.
