We report 510 records of 58 species belonging to the three lichen genera Cladonia P. Browne, Nephroma Ach. and Peltigera Willd. from 57 sites in the Prealps and Alps of Lombardia (Northern Italy). Four mountain sectors were investigated: the Orobic Prealps and Alps (19 sites), the Brescia Prealps (9 sites), the Adamello massif (8 sites), and the Rhaetian Alps (22 sites). Cladonia was represented by 39 species (415 records), Nephroma by 2 species (7 records), Peltigera by 17 species (88 records). Some relevant records are reported for species from each genus. Albeit all of the recorded species have been already reported from Lombardia and most of them are common and widespread, some records refer to species of conservation concern, and all of the data reported here can contribute at improving the knowledge on the distribution of these genera, which is at the base of a better understanding of their ecology and of any eventual conservation strategy

Two infrequent species from Italy, i.e. Inocybe obscurobadia (Basidiomycets) and Neournula pouchetii (Ascomycetes) are reported for the first time from Sicily (southern Italy). The two species were collected in the Monti Sicani Park within a non-native forest in the Site of Community Interest (SCI ITA040005) - Monte Cammarata, Contrada Salaci.

The author reports the first Balkan collection of the scarcely featured in the mycological literature Pholiota gallica based on material collected in Bulgaria. Description of the macro-morphology and microscopic features of the studied specimens is included, supplemented with illustrations.

The investigation of 20 populations of Pisolithus spp. collected from the Maltese Islands resulted in three different records. Pisolithus albus and P. marmoratus are new to Malta and were found associated with Eucalyptus spp. The third species, P. arhizus, was confirmed from two new stations and both were associated with Quercus ilex. A brief morphological and ecological comparison of the three species is given and supplemented by images and a dichotomous identification key

1707 specific and intraspecific taxa, 698 genera, 254 families are included in the historical fungi collection of the General Herbarium of Palermo, most of which are mycromycetes responsible for diseases on major agricultural crops, with backgrounds from all parts of the world. The most substantial nucleus is represented by the collections of the Italian Cryptogamic Herbarium in which many researchers of the XIX Century participated.
