Based on a set of characteristic morphological features and in accordance with the contemporary knowledge for the mayfly's taxonomy, four new species for the Bulgarian fauna are reported. They belong to the genera Rhithrogena and Ecdyonurus and are in larval and/or nymphal stage. Some ecological notes are given also. The finding of the species Caen...

... However, eight species of Sistotrema including the type species have a more developed hymenophore with a hydnoid, irpicoid to a poroid surface. While S. confluens and S. subconfluens L.W. Zhou have pileate-stipitate basidiome and a poroid to irpicoid hymenophores (Eriksson et al., 1984;Ryvarden & Gilbertson, 1994;Zhou & Qin, 2013;Bubner, Morgner, Stark, & Münzenberger, 2014), S. alboluteum (Bourdot & Galzin) Bondartsev & Singer, S. albopallescens (Bourdot & Galzin) Bondartsev & Singer, S. brunneolum Spirin & Zmitr., and S. dennisii Malençon have a poroid-resupinate hymenophore (Eriksson et al., 1984;Malençon, 1977;Spirin & Zmitrovich, 2007;Kout, 2008), and that of S. muscicola (Pers.) S. Lundell and S. raduloides (P. ...
We describe two new species of resupinate Sistotrema sensu lato (Cantharellales) collected in Japan: S. flavorhizomorphae and S. chloroporum. Both species have urniform basidia with more than four sterigmata and monomitic hyphal system, oil-rich hyphae in subiculum, which is typical for this genus. Sistotrema chloroporum is characterized by poroid hymenophore partly yellowish-green, basidia 4-6-spored, medium-sized basidiospores (4.5-6.5 × 3.5-6 µm), and broadleaf forest habitat. Sistotrema flavorhizomorphae is characterized by hydnoid-irpicoid hymenophore, bright yellowish rhizomorphs, basidia 6-8-spored, small basidiospores (3-3.5 × 2.5-3 µm), and pine forest habitat. Phylogenetic trees inferred from the fungal nrDNA ITS and LSU and the rpb2 sequences supported that both species were distinct and grouped with other ectomycorrhizal Sistotrema and Hydnum species, but their generic boundary was unclear. Mycorrhizae underneath basidiomes of both species were identified and described via molecular techniques. Mycorrhizae of S. chloroporum have similar characteristics to those of other Sistotrema s.l. and Hydnum species, i.e., S. confluens and H. repandum, whereas S. flavorhizomorphae has a distinct morpho-anatomy, for example, a distinct pseudoparenchymatous mantle. Comprehensive characterizations of basidiomes and mycorrhizae improve the taxonomic analysis of mycorrhizal species of Sistotrema s.l.
... A milestone work by KOTLABA (1984) summarized the ecology and distribution of all polyporoid species in the territory of former Czechoslovakia and constitutes a standard reference work for Czech (and Slovak) mycologists interested in polypores. Since then, many new species of polypores have been discovered for the Czech Republic ( KOTLABA & POUZAR 1985;KOUT 2008;KOUT et al. 2014;TOMŠOVSKÝ & JANKOVSKÝ 2008;TOMŠOVSKÝ et al. 2010b;VAMPOLA 1991aVAMPOLA , 1991bVAMPOLA , 1991cVAMPOLA , 1992aVAMPOLA , 1992bVAMPOLA , 1993aVAMPOLA , 1993bVAMPOLA , 1995aVAMPOLA , 1995bVAMPOLA , 1996VAMPOLA , 2008aVAMPOLA , 2008bVAMPOLA & POUZAR 1993, 1994, 1996a, 1996bVAMPOLA & VÁGNER 1995VAMPOLA & VLASÁK 1992, 2012VAMPOLA et al. 1995;VLASÁK 1990;VLASÁK & KOUT 2010;VLASÁK et al. 2012;ZÍBAROVÁ & KOUT 2014) and global knowledge of the biology and taxonomy of polyporoid species has improved considerably. In recent years, several smaller floristic studies and additions addressing various species of polypores have also made contributions (e.g. ...
Moravia – I. Acta Musei Moraviae, Scientiae biologicae (Brno) 102(1): 49–87. – An annotated list of some remarkable collections of rare polypores, mainly from the territory of Moravia, is given. Altogether, 36 species are presented, most of them illlustrated with a colour photograph. Some information on their distribution, ecology and key characters is provided. New localities of species previously known merely from only one (Aurantiporus alborubescens, Chaetoporellus latitans, Riopa metamorphosa) or two (Jahnoporus hirtus) in Czechia were disclosed, and a few species (Byssoporia terrestris, Phellinus lundellii) are published for the first time for the territory of Moravia. Further, many new localities for certain other very rare polypores (Gelatoporia subvermispora, Porotheleum fimbriatum, Tyromyces kmetii, Yuchengia narymica) are presented.
