摘要:Abstract(#br)Phylogenetic relationships in the genus Helvella were investigated using both LSU rDNA sequences and morphological features. The latter were coded and included in the analyses, resulting in better-supported clades. Helvella is monophyletic and Wynnella is its si...

摘要:Abstract(#br)An emendation of the generic description of Scleroderma is proposed to consider the membranaceous veil like, or granulose patches, both on the base of the globose basidiome or on the upper part of the stipe, formed by the growth of the basidiome, which breaks th...

摘要:Abstract(#br)The complex evolutionary history of the subtribe Physalinae is reflected in the poor resolution of the relationships of Physalis and the physaloid genera. We hypothesize that this low resolution is caused by recent evolutionary history in a complex geographic se...

摘要:The class Dacrymycetes has been considered a monophyletic group based on shared morphological characteristics and recent molecular studies, with bifurcate basidia and non perforate parenthosome as synapomorphies. In this review of the state of knowledge for Dacrymycetes (dacrymyc...
