Anti-phytopathogen terpenoid glycosides from the root bark of Chytranthus macrobotrys and Radlkofera calodendron
2020
Abstract Chytranthus macrobotrys and Radlkofera calodendron are two Sapindaceae characterized by a lack of phytochemical data. Both root barks from the two Sapindaceae species were processed by ethanol extraction followed by the isolation of their primary constituents by liquid chromatography. This process yielded four previously undescribed terpenoid glycosides together with eight known analogues. Extracts and isolated compounds from C. macrobotrys and R. calodendron were then screened for antimicrobial activity against fifteen phytopathogens. The biological screening also involved extracts and pure compounds from Blighia unijugata and Blighia welwitschii, two Sapindaceae previously studie…
The Potential Role of Medicinal Mushrooms in the Prevention and Treatment of Gynecological Cancers: A Review
2019
A review of scientific information about the potential role of medicinal mushrooms in the prevention and treatment of gynecological cancers, human immunodeficiency virus, and human papillomavirus infections is reported here. The results of in vivo and in vitro experiments on 16 different species of Basidiomycetes and three Ascomycetes, which possess chemopreventive potential and are effective in clinical application in combination with chemotherapy, are also discussed. Medicinal mushroom extracts confirm an evident efficacy on the reduction of tumor cell proliferation and side effects in patients with gynecological tumors who are undergoing chemotherapy treatments. This review, the first on…

2017
Inocybe castaneicolor sp. nov., collected in Sicily (Italy), is introduced with full description, line drawings, and color photographs. Its novelty is supported by both its morphology and molecular phylogenetic analysis. It is characterized by its castaneous brown pileus with an evident umbo and sloped margin, subfusiform cystidia and smooth subamygdaliformis to subnavicular spores. Comparison of I. castaneicolor with similar species is also provided.
Jaminaea phylloscopi sp. nov. (Microstromatales), a basidiomycetous yeast isolated from migratory birds in the Mediterranean basin.
2016
During a survey of yeasts vectored by migratory birds in the Mediterranean basin, isolations from the cloacae of members of the order Passeriformes collected in Ustica (Italy) were performed. Based on phylogenetic analysis of the D1/D2 domain of the 26S rRNA gene and the internal transcribed spacer ITS1-5.8S rRNA gene-ITS2 region, five yeast isolates clustered in a new lineage within the Microstromatales clade. The DNA sequences of these isolates differed from those of their closest relatives, Jaminaea angkorensis and Jaminaea lanaiensis, by 20 and 25 nt substitutions in the D1/D2 domain and 119 and 131 nt substitutions in the complete ITS region, respectively. In addition, the five isolate…
Updates to Finnish aphyllophoroid funga (Basidiomycota):new species and range extensions
2018
Abstract The knowledge of Finnish aphyllophoroid funga has increased substantially in recent years. In this article we present six species new to Finland: Cristinia (cf.) rhenana Grosse-Brauckm., Hyphodontiella hauerslevii K.H. Larss. & Hjortstam, Leptosporomyces montanus (Jülich) Ginns & M.N.L Lefebvre, Osteina obducta (Berk.) Donk, Sebacina helvelloides (Schwein.) Burt, and Tulasnella brinkmannii sensu lato Bres. The finding of Osteina obducta is the first record in Northern Europe. The article also contributes new records of 56 nationally rare species (maximum ten previous records in Finland). Additionally, we list 110 regionally new species, found for the first time from a certa…
Use of Ganoderma lucidum (Ganodermataceae, Basidiomycota) as Radioprotector
2020
For millennia, naturopaths and physicians have used Ganoderma lucidum (reishi mushroom) for its diverse therapeutic properties, as recorded in the oldest Chinese herbal encyclopedia. Indeed, a radioprotective effect has been reported in the isolated components of its extracts. A systematic review and meta-analyses (PRISMA) was conducted in March 2020, searching databases including PubMed, Scopus, Embase, and Google Scholar, along with Clinical Trials. The inclusion criteria were ex vivo, in vitro, and in vivo studies, with full texts in English, conducted to determine the radioprotective benefits of G. lucidum, or reports in which ionizing radiation was used. From a total number of 1109 rec…
Effect of the basidiomycete Poria cocos on experimental dermatitis and other inflammatory conditions.
1997
The hydroalcoholic extract from P. cocos was examined for oral and topical anti-inflammatory activities. It proved to be active against carrageenan, arachidonic acid, tetradecanoyl phorbol acetate (TPA) acute edemas, TPA chronic inflammation and oxazolone delayed hypersensitivity in mice. Two lanostane-type triterpenes were isolated and identified by spectroscopic methods as dehydrotumulosic and pachymic acids. Their ID50 on acute TPA edema was 4.7 x 10(-3) and 6.8 x 10(-4) mumol/ear, respectively.
Amaurodon mustialaënsis (Basidiomycota, Thelephoraceae) new to Italy
2014
Amaurodon mustialaensis is reported for the first time from Italy. Based on Italian specimens, a brief description, microscopical and macroscopical photographs, ecological and distributional data of this rare taxon are presented.
An adventive Panaeolus antillarum in Poland (Basidiomycota, Agaricales) with notes on its taxonomy, geographical distribution, and ecology
2014
Abstract Coprophilous fungus, Panaeolus antillarum rarely recorded in Europe, is reported here for the first time from the Augustow Plane, north-eastern Poland. This thermophilic species was found outdoors in August on horse dung mixed with straw. A chemical analysis did not confirm the presence of the psychoactive alkaloids in collected material. A complete description and illustration of the species based on Polish specimens are presented and notes on its taxonomy, ecology, world distribution and comparison with similar taxa — P. semiovatus var. semiovatus, P. semiovatus var. phalaenarum, and others are also provided.
Taxonomic notes and critical discussion on the status of Hydnum notarisii (Basidiomycota) through the evaluation of Giuseppe Inzenga's original study…
2016
The current taxonomic status of Hydnum notarisii Inzenga is here critically analyzed on the basis of Giuseppe Inzenga’s original description and of the specimens kept in his private herbarium hosted in the Istituto Agrario Castelnuovo (Palermo, Italy) and in the Herbarium of Museum of Evolution, Uppsala University, Sweden (UPS). The detailed morphological study of the original dried material through the use of compound optical and scanning electron microscopy demonstrated that this particular fungus possesses very similar features with Hericium erinaceus (Bull.)
