Primo contributo lichenologico nella Riserva Naturale Orientata di Bosco della Favara e Bosco Granza (Sicilia centro-settentrionale).
2008
Oggetto del nostro contributo il censimento della flora lichenica del territorio di Montemaggiore Belsito facente del sito ZPS ITA020032 “Boschi di Granza e Bosco di Favara.Il territorio in esame ampiamente studiato dal punto di vista vegetazionale e floristico relativamente alle fanerogame (2), non risulta finora studiato sotto l’aspetto lichenico .L’area in esame è denominata Valle del Torto ed è compresa nella tavola I.G.M., 1:25.000, F. 259 I: S.O. (Montemaggiore Belsito). Essa si estende su un ampio territorio ricadente nei comuni di Montemaggiore Belsito, Cerda, Sclafani Bagni, Caltavuturo e Caccamo. Tale studio appare significativo per comprendere il mosaico delle conoscenze floristi…
Macromycetes' diversity in Tunisia
2017
In Tunisia, about 12% of the country area is covered by forests which have favorable climatic factors likely to harbor a high macrofungal biodiversity. However, this valuable bioresource remains understudied especially regarding their distribution, ecology, abundance and diversity. The initiation of the first national inventory of macrofungi in NorthWestern Tunisian forests was published by our group in 2016. The study covered six governorates, sixty seven sites and enabled the identification of one hundred and twenty-three specimens. Abiotic environmental factors such (as bioclimatic stage, rainfall and edaphic conditions) and biotic factors (plant association and nature and density of the…

Recording and mapping the Mediterranean mycota: the case of Sicily (S Italy)
2009
The assessment of fungal diversity in the Mediterranean area is considered by mycologists as a priority target. In recent times a number of associations, commissions and international networks recognized fungi as important tools to be included in research projects. The newly established Mediterranean Mycology Working Group with the European Mycological Association could be the focal point for increasing mycological research in the Mediterranean area. According to its strategic position in the Mediterranean Basin, Sicily could be considered a centre of diversity and a reference area. The evaluation and exploitation of fungal biodiversity in Sicily is illustrated here.
Polymorphism of ITS1 and ITS2 regions within and between three distant population of Schizophyllum commune
2017
Schizophyllum commune is one of the most widely distributed fungi and can be isolated from all continents, except for Antarctica. It has an important role as wood decomposer since it is mostly found on fallen branches and timber of deciduous trees, but it can also colonize softwood as well as grass silage. As an edible and medicinal mushroom, it has been shown to have various biological functions including anti-tumor, antioxidative and anti-inflammatory activity. Investigation of molecular diversity of this cosmopolitan species is important since it can make us understand what genetic traits are important in maintaining the global success of this species. In this study we analyzed polymorph…
Taxonomic study on Allium dentiferum Webb & Berth. (Alliaceae) and its relations with allied species from the Mediterranean.
2008
Taxonomy and relationships of Allium dentiferum, a polyploid synanthropic Mediterranean species, are assessed based on morphological, karyological and cladistic analysis. A new species, Allium galileum, closely related to A. dentiferum, is described and illustrated. Both species are large and share very long spathe valves, yellow-greenish tepals and interstaminal teeth. The new species, however, is diploid and linked to natural habitats, and is characterized by the lax and spread inflorescence, purple stamen filaments and the smaller perigon, anthers, ovary and capsule. Relationships among these two species and allied taxa of Allium sect. Codonoprasum, such as A. fuscum, A. pallens, A. pani…
Mycena pseudoinclinata, new to Italy
2012
The first report of Mycena pseudoinclinata in Italy is accompanied by notes on the taxonomy, ecology, and distribution of this uncommon basidiomycete.
Brassica carinata (Cruciferae) spontaneizzata in Sicilia
2009
Brassica carinata (Cruciferae) naturalized in Sicily. Brassica carinata (Cruciferae) is reported occurring naturalized in Sicily. Two small populations of this taxon of hybrid origin, introduced in cultivation for production of combustible oilseeds in several countries of the Mediterranean region, including Sicily, have been found growing in hemerophilous conditions at the borders of the A.19 Palermo-Catania motorway, in locality Tremonzelli (Central Sicily).
Typification and taxonomic characterization of Thymus longicaulis C. Presl (Lamiaceae)
2014
Thymus longicaulis, described from Sicily by Carl Bořivoj Presl, is a critical Mediterranean species, often confused with other taxa belonging to Th. sect. Serpyllum. In order to preserve the current application of this name, a lecotype is designated. Furthermore a detailed morphological description and information about habitat, phenology, distribution, karyology and taxonomy are provided.
