A re-examination of herbarium material together with some new finds from Southern Italy (the regions Basilicata, Calabria, Campania, Puglia and Sicilia) resulted in a list of 39 lichenicolous fungi (and 8 species of lichenicolous lichens). Six of them are new to Italy [Arthonia caerulescens (Almq.) R.Sant., Arthonia protoparmeliae Etayo, Arthonia xanthoparmeliarum Etayo, Tremella diploschistina Millanes & al., Verrucoccum coppinsii V. Atienza & al. and Zwackhiomyces polischukii Darmostuk & Khodos.] and 13 new to the respective region. The species Lichenotubeufia calabrica Brackel, Sphaerellothecium nimisii Brackel & Puntillo and Stigmidium hypogymniae Brackel are described as new to science

This paper clarifies the taxonomy and nomenclature of a characteristic calcicolous lichen, formerly called Caloplaca subochracea auct., which is widespread in coastal areas of the Mediterranean region. In spite of being easily recognizable, this lichen was often misunderstood, and has a very complicated nomenclatural history. The analysis of the type material of Callopisma marmoratum Bagl., described from Sardinia in 1879, revealed that it is identical to Caloplaca subochracea auct., and has nothing to do with the lichen currently called Xanthocarpia marmorata (Bagl.) Frödén, Arup & Søchting. The results of molecular analysis showed that Caloplaca subochracea auct. belongs to Gyalolechia, and that two closely related species can be recognized; formerly these were treated as varieties with differently pigmented thalli, and are recombined here as Gyalolechia marmorata (Bagl.) Nimis & Arup, and G. luteococcinea (Clauzade & Cl. Roux) Cl. Roux, M. Bertrand & Arup. Finally, the name Xanthocarpia fulva (Harm.) Nav.-Ros. & Cl. Roux, is introduced to replace Xanthocarpia marmorata.

Records of macrofungi from Gozo are few and underrepresented when compared to those found in mainland Malta. An investigation on the macrofungi occurring on Gozo has been carried out to narrow this knowledge gap. During the present study, 147 samples were collected from Gozo between October 2019 and April 2021. From this sampling effort, 70 different species of macrofungi were identified, of which 61 were new records for Gozo and 45 were new records for the Maltese Islands. Five of these new records (one new to science) were already published during the progress of this work, whereas the remaining 40 new records are reported for the first time in this account. This investigation elevated the number of macrofungi in Gozo from 36 (prior to the onset of this work) to 97 species. For each of the 40 new records, a detailed account of the examined material, ecology, macro- and micro- morphology, and notes related to the taxonomy and closely related species are provided. An annotated checklist of all the 97 species occurring in Gozo is given, and details on the locations of each collection are also included. The main threats that local macrofungi are currently facing in Malta and Gozo are for the first time exposed, and conservation measures are discussed

The arcto-montane thalloid liverwort Mannia triandra is reported for the first time in Spain, on the Balearic Island of Mallorca. The species was discovered in December 2022 at a unique location in the famous and bryologically celebrated Serra de Tramuntana. The specimens from Mallorca and their ecological environment are described. Diagnostic characters are discussed and a comparison is made with other Marchantiales species with which confusion is possible. A key to Mediterranean Mannia and Asterella without spores is provided.

Quercus faginea woods in Alvados valley are remnants of ancient forest within a strongly fragmented and diverse human-made matrix. In this contribution, new data concerning lichen diversity characterizing this area are presented, including two species new to Portugal. More than 20% of the species are typical of undisturbed, natural environments confirming these woods to be important areas for preservation of specific lichen flora.

In the last decades, lichenological studies started again in Lombardia (N Italy), where locally overlooked situations persist. One of such areas is the southernmost part of the Pavese Apennine, where the highest mountains of the Province of Pavia are located. We report the results of a thorough lichen survey carried out in the Natura 2000 Habitat 9130 “Asperulo Fagetum beech forests” occurring along the Monte Lesima-Cima Colletta ridge, an area with an outstanding naturalistic relevance, part of which is included within the SCI IT2080025 “Le Torraie-Monte Lesima”. Ninety-two taxa are recorded from four sites with different features, with the richest site hosting old beech trees and rock outcrops. Circinaria coronata, Glaucomaria subcarpinea, Gyalolechia marmorata, Leproplaca chrysodeta, Pertusaria coronata, Physconia servitii, Variospora paulii and Wadeana dendrographa are new to Lombardia.
