Murinicarpus subadustus described from China is the only species of the genus Murinicarpus ( Polyporales , Basidiomycota ). There is no other report of this genus from any other country except China. Here, we report M. subadustus as a novelty to the macrofungal biota of India. This unique species is identified based on morphological features and nrDNA ITS-based phylogenetic analysis. A thorough macro- and microscopic characterisation along with field photographs, line drawings of microscopic structures and comparisons with morphologically and phylogenetically related taxa are provided.

Opportunistic and nosocomial human infections by various Candida species are of serious global health concern especially due to the spread of drug resistant strains and lack of treatment options. One of the main problems of bioprospecting for novel antimycotics is the rediscovery of already known molecules. To reduce the chances of such rediscoveries, one option is to search for unique metabolites from microbes of less studied and extreme habitats. Thirty-five fungal strains were isolated from solar salterns and the methanolic extracts of their culture supernatants were tested for the inhibition of human-pathogenic Candida albicans , C. dubliniensis , C. glabrata , C. lusitaniae , C. tropicalis , and two clinical isolates of C. auris . Of the fungi screened, two, viz. Curvularia nodosa and Fusarium cf. foetens , showed significant growth inhibition of all the Candida species. Although the effective molecules were not identified in this preliminary screening, it highlights the importance of bioprospecting fungi from extreme environments which have been neglected in the search for novel antibiotics.

Prior to this study, Jahnula bipileata had only been found in the United States and Iraq, whereas J. dianchia had only been recorded in China. The two species are described, illustrated and compared with the existing collections herein. A key to Jahnula species recorded in Egypt is provided.

Cadophora orchidicola , a root-associated asexual species, did not have a clear placement within the paraphyletic genus Cadophora because it was not represented by sequences derived from the type material . Based on four newly obtained molecular marker sequences from the ex-type strain, a new genus, Leptodophora , is proposed, typified with C. orchidicola , as well as new combinations for three recently described and closely related species. In addition, a new species, Collembolispora disimilis , is proposed for a fungus producing phialidic conidiogenous cells and previously treated as Cadophora sp.

“Old-growth forests” comprise habitats from untouched, primeval forests to partially man-influenced, near-natural forests. Some fungal species occur preferably in these forests with a high degree of naturalness. Occurrence data from Slovakia for five wood-inhabiting fungal species was processed. The numbers of known localities of these species in Slovakia range from 4 to 49. The five species prefer different stages of wood decay when producing fruitbodies. Records of the studied species indicate that Amylocystis lapponica and Ionomidotis irregularis occur only in old-growth forests, especially in the best-preserved virgin and natural ones, in Slovakia typically on wood of only one or two tree species. Antrodia labyrinthica occurs in natural and nearnatural forests, while the remaining two species can survive in managed forests with a natural tree composition, localised close to forests of higher naturalness (Skeletocutis odora) or even in more intensively managed forests with a small amount of decaying wood and parks (Yuchengia narymica). The substantial increase in the number of records of some species in Slovakia can be related to more intensive research in montane old-growth forests (e.g. Amylocystis lapponica) or probably to a massive spread of species (Yuchengia narymica), even in a wide elevation range.

Dendrothele nivosa is a rare Mediterranean lignicolous species, growing on representatives of the genus Juniperus , hitherto unknown from the Balkans. This wood-decaying fungus was collected on living branches of Savin juniper, a rare and protected plant species, included in the Bulgarian Biological Diversity Act. Dendrothele nivosa is considered to be a white rot saprobe with a restricted range following the distribution of the juniper host.

The bryophilous ascomycete Octospora meslinii is a rarely reported species growing exclusively in cushions of the saxicolous moss Grimmia pulvinata. The taxon has been misunderstood in the past and hitherto reliably only reported from France and Germany. Many recent collections from Hungary have made it possible to get a better understanding of O. meslinii, which is comprehensively described and illustrated in this paper. Because of the lack of original material, we designate an illustration in the protologue as the lectotype and one of the recent collections as the epitype of this fungus. Octospora meslinii is compared with other species of Octospora growing in the same type of habitat or having similar ascospores. The most closely related species to O. meslinii is O. pseudoampezzana. Both share apothecia with blackish pigmentation, a unique feature compared to bryophilous Pezizales as a whole, ellipsoid ascospores ornamented with isolated warts, moss hosts in the family Grimmiaceae, and the infection inducing galls on the rhizoids. A phylogenetic analysis using the EF1 , LSU and SSU rDNA loci confirms our morphological findings showing that O. meslinii forms a monophyletic clade with O. pseudoampezzana, whereas other species with which O. meslinii was confused in the past, e.g. O. similis, are related only distantly.

Triadelphia (Ascomycota, Microascales) is a genus encompassing pleomorphic dematiaceous micromycetes occurring sporadically on rotting wood and other plant material, infrequently also on other substrates. In this study, we document a second record of Triadelphia morgoensis, found on a twig of Populus nigra near Prague (Czech Republic), after its original description from decaying wood in Hungary. This fungus is characterised by the production of three types of conidia. The identification was achieved by a combination of morphological, physiological and genetic traits. The description of the fungus is emended, and its differentiation from similar species is discussed. Multigene phylogeny showed that T. morgoensis is most closely related to T. loudetiae and T. heterospora. The DNA data from three loci generated in this study (ITS, LSU, RPB2) will facilitate identification of the species in the future. Our results add to the knowledge on the ecology and phylogeny of this understudied fungus, for which neither living type material nor a molecular sequence has been preserved.
