Drying process is commonly used to allow long time storage of valuable porcini mushrooms (Boletus edulis). Although considered a stable product dried porcini flavour changes during storage. Monitoring of volatile compounds during shelf life may help to understand the nature of the observed changes. In the present work two mass spectrometric techniques were used to monitor the evolution of volat...

Abstract Only two Coccoloba -associated xerocomoid boletes with smooth basidiospores are currently known from the Dominican Republic, namely Boletus ruborculus and Xerocomus coccolobae . A multilocus phylogenetic analysis of four gene markers (ITS, LSU, RPB2 , TEF1 ) reveals that B forms an autonomous clade in Boletaceae corresponding to a novel genus, which is introduced here as Tropicoboletus...

Abstract B. edulis , collected from 33 forested or woodland sites across Poland over 25 years since 1995, were analysed for radiocaesium. The results ( 137 Cs activity range: to 10,000 Bq kg -1 dry weight) provide a good indication of artificial radioactivity in this food material. relatively higher levels detected the earlier years, mostly easterly location, is consistent with depositions proj...

Quercus pyrenaica-dominated forests are very widely distributed in Mediterranean ecosystems. Traditional forest use, such as coppicing to obtain firewood or livestock grazing under silvopastoral systems, and the current social abandonment of rural environment have given rise structures different ages at stages development. Thus, on one hand, there large areas Q. pyrenaica coppice systems that p...
