Integrative taxonomy reveals an unexpected diversity in Geastrum section Geastrum (Geastrales, Basidiomycota).

A revision of the classification of Geastrum sect. Geastrum is presented on the basis of an integrative taxonomic approach, which involves the study of morphological, molecular, ecological, and chorological data. Four DNA regions are analysed: the ITS and LSU nrDNA, rpb1, and atp6.

The diversity of Terfezia desert truffles: new species and a highly variable species complex with intrasporocarpic nrDNA ITS heterogeneity.

Desert truffles belonging to Terfezia are well known mycorrhizal members of the mycota of the Mediterranean region and the Middle East. We aimed to test (i) whether the morphological criteria of Terfezia species regularly collected in Spain enable their separation and (ii) whether the previously hypothesized edaphic/biotic specificity of one group could be confirmed by study of a larger number of specimens. The species T.

Bovista sclerocystis, a new species from Mexico.

Bovista sclerocystis is described as a new species. It was found in Mexico, growing on rich soil of a tropical forest. It belongs to section Globaria, series Albosquamosa.

Calvatia sporocristata sp. nov. (Gasteromycetes) from Costa Rica.

Calvatia sporocristata, Gasteromycetes, is described and illustrated as a new species. Its taxonomic characters are discussed and compared with other closely related species of the genus. Few studies have been carried out on tropical Gasteromycetes.

[Tactics in the umbilical approach in abdominoplasties].

The authors review 58 female patients, submitted to abdominoplasty. They utilized a technical approach that permitted to obtain umbilical scars similar to the normal ones.
