Mycobiota of three Boletus edulis (and allied species) productive sites
No full textBoletus edulis and allied species (porcini) are one of the most appreciated and consumed species in the world. Despite their ecological and economic importance, little information is available on the mycobiota that characterize their natural growing habitats. Due to the importance to preserve the areas where these precious species grow, three different broadleaf sites were investigated to describe the above ground macrofungal communities. These forests, located in North-west Italy (Liguria), were intensively surveyed over three consecutive years by sporomata analysis. Altogether 243 fungal taxa were recorded in the selected 60 plots. The statistical results reveal that the studied sites, despite differing in vegetation type, are very similar in macrofungal species richness and composition. The ectomycorrhizal fungal group was the richest both in number and percentage. Comparisons of our results with other European mycological investigations suggest that porcini broadleaf sites are characterized by a similar and peculiar mycobiota
Macrofungi in the historical “Hanbury” Botanical Gardens (Liguria, NW Italy): a preliminary check-list
No full textThis paper presents the results of the study on the mycoflora of a botanical garden located in Liguria (NW Italy). Mycological investigations were performed to list the presence of both epigeous and hypogeous macrofungal species in the historical Hanbury Botanical Gardens. The results show that several interesting and uncommon species, especially among hypogeous fungi, occur in the site. Ectomycorrhizal species and soil saprotrophs were more numerous than woody decaying and parasite fungi. This site, declared a Regional Protected Area and a Site of Community Importance for its high plant biodiversity, also constitutes an interesting area from a mycological perspective. Due to the importance of fungi in terrestrial ecosystems functioning and their potential interactions with plants, further studies should be planned in order to increase knowledge on the fungal components that can are present in botanical gardens
Concordance between vascular plant and macrofungal community composition in broadleaf deciduous forests in central Italy.
No full textWe examined the concordance between vascular plants and macrofungi (grouped into trophic groups) in Mediterranean forest habitats (central Italy). Our goal was to test how consistently plant and fungi groups classify plots in a broadleaf deciduous forest dominated by Quercus cerris. Our hypothesis was that groups of plants can be used as surrogates for the classification of macrofungal communities. The test of concordance comprised two steps: (1) the plant species data sets were subjected to cluster analysis, to obtain three classifications based on presence of all plants, presence and frequency of only woody species; (2) Multiple Response Permutation Procedures (MRPP) was used to test the performance of each plant classification applied to the fungi datasets. Sample scores on the first PCA axis were used to investigate the relationships between compositional patterns. In the concordance analysis, the classification based on woody plants only provided better results than the classification obtained using both herbaceous and woody plants. Cross-tests gave the best results when the “woody plants” classification was applied to ectomycorrhizal fungi (EMF) and, to a certain extent, to humicolous saprotrophs (Sh). The ordination analysis suggested that the frequency of woody plants follows a similar spatial distribution to EMF and Sh fungal groups and is therefore expected to covariate along the same environmental gradients. Many EMF exhibit preferences for few (one or two) hosts. Significant ssociations were found among numerous EMF and woody plant species. Woody plants such as Sorbus domestica and Prunus spinosa appear to be associated with many EMF. The combination of a high frequency of raxinus oxycarpa and Quercus petraea seems to promote distinct assemblages of EMF and Sh fungi. Characteristic assemblages of fungi were found in association with certain tree and shrub combinations
