Contribution to the knowledge of the genus Phlebia in Italy

Abstract

The presence of two corticioid taxa belonging to the genus Phlebia (Basidiomycota), collected from Sicily, Italy is reported. A macro-and micromorphological descriptions of P. acanthocystis and P. nothofagi added of ecological and distributional data are here provided. P. acanthocystis is reported as new for Italy.

Hidden in the dark under umbrellas: two new Psilolechia species (lichenized Ascomycota, Lecanorales) described from the Czech Republic

“…The genus Psilolechia contains a spectrum of various metabolite substance classes (following Elix 2018): pulvinic acid derivatives (rhizocarpic acid), orcinol tridepsides (gyrophoric acid), dibenzofurans (porphyrilic acid), unidentified (tri-)terpenoids and β-orcinol depsides (atranorin) (Coppins & Purvis 1987;Yoshimura & Harada 2004;Czarnota & Kukwa 2008). Some of the unidentified compounds may belong to other substance classes.…”

“…Tønsberg (1992) noted traces of an unknown substance in corticolous Norwegian material without further specification. In Polish specimens of P. lucida, Czarnota & Kukwa (2008) detected at least 7 unknown accessory substances by TLC that they tentatively identified as terpenoids. Yoshimura & Harada (2004) reported the presence of atranorin in P. lucida (otherwise not known either from this species or the genus) from Japan, but using a more sensitive HPLC method.…”

“…is morphologically a relatively well circumscribed group of small crustose microlichens forming visible extensive thalli. It is characterized by emarginate convex apothecia, asci showing an amyloid tubular structure (Micarea-/ Porpidia-type) after IKI treatment, small simple dacryoid to elongate-ellipsoid ascospores usually not exceeding 7 × 2 µm in diam., and absence of pycnidia (Coppins & Purvis 1987;Czarnota & Kukwa 2008;Gilbert et al 2009). Although pycnidia are unknown in the genus, a hyphomycetous anamorph has been described from one species, P. clavulifera (Coppins & Purvis 1987).…”

“…Currently, only four species are known in the genus Psilolechia worldwide (Lücking et al 2017). Two of them (P. lucida, P. clavulifera) are widespread, subcosmopolitan lichens growing on a variety of substrates, but with different ecological preferences (see Coppins & Purvis 1987;Czarnota & Kukwa 2008). The third species (P. leprosa) is a rare substrate specialist occurring almost exclusively on copper-rich rocks (Coppins & Purvis 1987), but has been reported also from volcanic lahar flows in the Canary Isles and Kamchatka (Berger & Etayo 1998;Vereshchagin et al 2023).…”

New records of corticioid fungi from Sicily

“…Data on diversity and distribution of aphyllophoroid species in Sicily were published in several papers (Saitta et al 2004;Bernicchia et al 2007;Bernicchia et al 2008;Saitta and Venturella 2010;Saitta et al 2011). New distributional and ecological information on new, uncommon and/or rare corticioid species has been recently published (Saitta and Melo 2012;Gorjón and Saitta 2014;Pecoraro et al 2014;Saitta et al 2014aSaitta et al , 2014b. The number of recorded corticioid species in Sicily is 102 (see Appendix) excluding the new records herein.…”
