A reappraisal of the Pleurotus eryngii complex – New species and taxonomic combinations based on the application of a polyphasic approach, and an ide…

2014

The Pleurotus eryngii species-complex comprises choice edible mushrooms growing on roots and lower stem residues of Apiaceae (umbellifers) plants. Material deriving from extensive sampling was studied by mating compatibility, morphological and ecological criteria, and through analysis of ITS1-5.8S-ITS2 and IGS1 rRNA sequences. Results revealed that P. eryngii sensu stricto forms a diverse and widely distributed aggregate composed of varieties elaeoselini, eryngii, ferulae, thapsiae, and tingitanus. Pleurotus eryngii subsp. tuoliensis comb. nov. is a phylogenetically sister group to the former growing only on various Ferula species in Asia. The existence of Pleurotus nebrodensis outside of S…

Taxonomic Identity, Geographic Distribution, and Commercial Exploitation of the Culinary-Medicinal Mushroom Pleurotus nebrodensis (Basidiomycetes)

2016

An updated overview of the outcome of studies conducted on the culinary-medicinal mushroom Pleurotus nebrodensis is presented by placing emphasis on the clarification of the taxonomic identity of P. nebrodensis and other related taxa possessing entirely white to cream basidiomes, which grow in association with different plants of the family Apiaceae. Cultivation techniques, quality of the product sold and sales price, as well as nutritional and medicinal aspects are discussed. Taking also into consideration the high economic importance of P. nebrodensis, it is essential to proceed with the verification of the commercial strains currently available in the international market under the name …

Medicinal mushrooms: Valuable biological resources of high exploitation potential

2017

Higher Basidiomycetes and Ascomycetes mushrooms possess various immunological and anticancer properties. They also offer important health benefits and exhibit a broad spectrum of pharmacological activities including antibacterial, antifungal, antiviral, cytotoxic, immunomodulating, anti-inflammatory, antioxidative, antiallergic, antidepressive, antihyperlipidemic, antidiabetic, digestive, hepatoprotective, neuroprotective, nephroprotective, osteoprotective, and hypotensive activities. This minireview summarizes the perspectives, recent advances, and major challenges of medicinal mushrooms with reference to their nutraceutical properties and dietary value, the production of mushroom biomass …

Genetic polymorphism and taxonomic infrastructure of the Pleurotus eryngii species-complex as determined by RAPD analysis, isozyme profiles and ecomo…

2001

The Pleurotus eryngii species-complex includes populations of choice edible mushrooms, growing in the greater Mediterranean area in close association with different genera of plants of the family Apiaceae. Their distinct host-specialization served as the principal criterion for the discrimination of several taxa; however, the genetic relationships among the various P. eryngii ecotypes remain ambiguous. In the present study, 46 Pleurotus strains with a wide range of geographical origins were isolated from Eryngium spp., Ferula communis, Cachrys ferulacea, Thapsia garganica and Elaeoselinum asclepium subsp. asclepium, and were subjected to isozyme and random amplified polymorphic DNA-PCR (RAP…

Pleurotus eryngii var. thapsiae var. nov. from Sicily

2002

Field investigation in the Sicilian territory allowed the study of Pleurotus eryngii basidiomata growing in association with Thapsia garganica. The evaluation of morphological, ecological, distribution and isozyme, and PCR-RAPD data together with a revision of Bresadola's herbarium specimens kept in the Herbarium Botanische Staatssamlung (M) led to the description of a new variety, Pleurotus eryngii var. tahpsiae var. nov.

Medicinal Mushrooms as Part of the "Third Mission" Activities of Univesities - A Science to Business Initiative Related to Mycotherapy

2021

In Italy, the National Agency for the Evaluation of the University System and Research (ANVUR) carries out a systematic evaluation of the "Third Mission" activities of universities and research bodies. In this perspective, universities already engaged in research on medicinal mushrooms and on their potential applications in the industrial sector set the frame for collaboration with large, well-reputed private companies. In Italy, one of the major problems of mycotherapy is related to lack of certification and the dubious origin/identity of mushroom extracts used by the industry. Hence, products deriving from medicinal mushrooms that are in trade do not often meet the required quality criter…

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.)

Pleurotus opuntiae revisited e An insight to the phylogeny of dimitic Pleurotus species with emphasis on the P. djamor complex

2018

Abstract The name Pleurotus opuntiae is indiscriminately used for describing mushrooms with white to off-white to white-grey pilei with short or absent stipe and dimitic hyphal system, which grow on plants of the genera Opuntia, Yucca, Agave, Phytolacca etc. However, the outcome of the present study evidences that this name should be reserved for specimens deriving from the Mediterranean area only; an epitype originating from Italy on Opuntia ficus-indica is designated. Pertinent material was sequenced by using the internal transcribed spacer region (ITS) and found to be phylogenetically related to P. djamor from Kenya and Nigeria, while members of the P. djamor complex from other continent…
