Lichenological studies in Sicily: a thorough biblography (1692-2020)
2020
A bibliography on lichens in Sicily has been compiled and is here provided, as a comprehensive source to facilitate further studies focused on the regional territory. We checked the available literature from 1692 to 2020. We listed alphabetically a selection of 397 key publications and provided some comments on their distribution in time and space, and on the main studied topics. The complete reference list is freely available online.
Aphyllophoraceous wood-inhabiting fungi on Quercus spp. in Italy
2008
240 species representing 100 genera of aphyllophoraceous fungi growing on Quercus spp. in Italy are listed. Some species are considered rare or infrequent in Italy, e.g. Bulbillomyces farinosus, Dendrothele dryina, Fomitopsis iberica, F. spraguei, Hyphoderma incrustatum, Inonotus andersonii.
Allium albanicum (Amaryllidaceae), a new species from Balkans and its relationships with A. meteoricum Heldr. & Hausskn. ex Halácsy
2019
A new species, Alliumalbanicum, is described and illustrated from Albania (Balkan Peninsula). It grows on serpentines or limestone in open rocky stands with a scattered distribution, mainly in mountain locations. Previously, the populations of this geophyte were attributed to A.meteoricum Heldr. & Hausskn. ex Halácsy, described from a few localities of North and Central Greece. These two species indeed show close relationships, chiefly regarding some features of the spathe valves, inflorescence and floral parts. They also share the same diploid chromosome number 2n =16 and similar karyotype, while seed testa micro-sculptures and leaf anatomy reveal remarkable differences. There are …
Typification of the name Papaver hybridum L. (Papaveraceae)
2011
The typification of the Linnaean name Papaver hybridum is discussed. A specimen in the Burser Herbarium at Uppsala is designated as lectotype.
An analysis of botanical studies of vascular plants from Italian wetlands
2022
Wetlands are essential for life on Earth, but at the same time the most threatened environments due to the gradual alterations associated with climate change and human action. The botanical studies on wetland higher plants carried out in Italy from 1950 until today are analysed in this survey. The 1,265 contributions resulting from this study are analysed from a historical, geographical, and content point of view. Most of the scientific contributions were published in the 1980s and 1990s, often by the same research groups and on a local scale. The predominant research theme is the inventory. Most papers are mainly focused on lakes and rivers. The results of this literature survey point to t…
A critical conspectus of Italian Lycopodiaceae
2015
As a result of our work on the Lycopodiaceae account for the Critical Flora of Italy, a new, synonymic inventory of Italian taxa is presented, based on herbarium studies and critical re-examination of extant literature. Three genera with eight species are accepted: Huperzia (1 species), Lycopodiella (1), and Lycopodium (6). An additional, ninth species (Lycopodiella cernua) is listed as a casual alien. The genus Diphasiastrum, accepted in several recent works, is treated at sectional level within Lycopodium (three species and their three hybrids). Lycopodium lagopus ( = L. clavatum subsp. monostachyon) is a recent addition to the Italian flora. Images of five types and Internet URI of other…
Conspectus of Italian Selaginella (Selaginellaceae), with some typifications
2015
An annotated synonymic inventory of Italian Selaginella taxa, a practical key for their identification and their dot distribution maps are presented, as a result of our work on the Selaginellaceae account for the Flora Critica d'Italia. The names Lycopodium helveticum L. and Selaginella denticulata var. platystachya Hieron. are typified.

An outline of the Madonie Mountains (northern Sicily): a center of diversity for Pleurotus species
2013
The territory of the Madonie Mountains is considered as a biodiversity hot-spot in the Mediterranean Basin. Since long ago distinguished botanists who have studied the vegetation of this particular territory were fascinated by the high level of species diversity. In this chapter, an overview of the geographical, geological, soil, climatic and vegetation features of the area is provided. Madonie territory is an important center of diversity for fungi and in particular for species belonging to the genus Pleurotus growing on roots of plants of the family Apiaceae.
Iconografia della storia naturale delle Madonie
2011
Con lo spirito di divulgare l'opera di Francesco Minà Palumbo, alcuni fra coloro che negli ultimi decenni hanno contribuito allo studio del patrimonio naturale e naturale delle Madonie hanno aderito all'iniziativa promossa dal museo Naturalistico di Castelbuono dedicato allo scienziato e dal Dipartimento di Scienze Botaniche di Palermo per sostenere l'onere della pubblicazione concessa dagli eredi all'Editore Sellerio di Palermo.
