In many western North American forests, prescribed burning and mechanical thinning are widely used to reduce fuels and restore stand conditions after a century of fire suppression. Few studies have followed the relative impacts of these treatments on the production and consumption of truffles in forest ecosystems, particularly in the Sierra Nevada of California. Using a full-factorial completel...

Two specimens of Tuber aestivum sensu lato from China were found between T. aestivum ascomata for sale in Italy. The morphological features of these ascomata were intermediate between those of T. aestivum and Tuber mesentericum. The spores were roundish and smaller than those of T. mesentericum and T. aestivum. Phylogenetic analyses showed that the Chinese specimens are placed in a separate cla...

Ascomata of two truffle species, Tuber borchii and T. asa-foetida, both naturally growing in woodlands of the Basilicata region (southern Italy), were identified on the basis of ascospore morphology and compared under a volatile organic compound profile to determine the particular volatile organic compounds that characterize each taxon. Solid-phase microextraction-gas chromatography-mass spectr...

decline in timber harvesting from federal forests. The harvest of these products involves complex and interrelated social, economic, managerial, nd biological issues ( ee Savage 1995; Molina et al. 1997). Although timber typically exceeds nontimber forest products in value, opportunities xist o manage for both, to the benefit of different groups. Of nontimber products, the wild mushroom industr...

The alignment of the 28S gene of several species of Pezizales allowed to select two pairs of primers able to amplify the internal transcribed spacer region of ribosomal DNA in mycorrhizal fungi, such as truffles. The higher yield of the amplification product demonstrates a better annealing of the new primers to the rDNA, as compared to the universal primers internal transcribed spacer 1 and int...
