Opis:
Africa is a diverse continent composed of many different terrestrial biomes, from the largest nonpolar desert in the world to equatorial forests and Southern African Fynbos. Biodiversity within the continent is high but much remains to be discovered. Sightings of hypogeous fruiting bodies of mycorrhizal fungi (truffles and truffle-like fungi) have been recorded from the most northern countries of the continent to the most southern countries; they have been widely collected for culinary and medicinal purposes. In this review, we describe the most prominent species of mycorrhizal fungi forming hypogeal fruiting bodies, across six genera. The most ubiquitous of these are the “desert truffle” species and the most common genus of plants with which they associate are those of the genus Helianthemum. We also describe the key species of truffle and truffle-like fungi in continental Africa. Where information exists, we describe the ecology, medicinal properties, and ethnomycology of the identified fungi.

Opis:
In this study, we examined the effect of the presence of mycorrhiza and ascomata of summer truffle (Tuber aestivum) on the bacterial composition of roots from small trees growing in selected sites of the Nida Basin. Qualitative DNA sequencing methods such as Sanger and next-generation sequencing (NGS) were used. The Sanger method revealed different bacterial species compositions between the samples where summer truffle ascomata was recorded and control samples. Five genera of bacteria could be distinguished: Bacillus, Erwinia, Pseudomonas, Rahnella and Serratia, among which the most numerous were Pseudomonas (Gammmaproteobacteria class) at 32.9%. The results obtained by the NGS method also showed differences in species composition of the bacteria depending on the study sample. Seven genera of bacteria were distinguished: Rhizorhabdus, Methylotenera, Sphingomonas, Nitrosospira, Streptomyces, Methyloceanibacter and Niastella, which dominated in roots from the truffle sites. Telmatobacter, Roseiarcus, Granulicella, Paludibaculum, Acidipila, Acidisphaera and Aliidongia dominated in roots from the control sites. With the NGS method, it is possible to identify the microbiome of a whole root, while only a root fragment can be analysed by the Sanger method. These results extend the scope of knowledge on the preferences of certain groups of bacteria associated with truffles and their influence on the formation of ascomata in summer truffles. Our results may also be useful in selecting and monitoring sites that promote ascomata of Tuber aestivum.

Opis:
In this paper we discuss the data on presence of truffles (Tuber spp.) in Polish literature and culture through the ages. The aim of this article was to give the historical data on truffles as well as the new ones together with the ongoing research on that ultimate fungi. Study concerning widely understood history of and research on truffles in Poland was based on review of literature dating back to XVII century. A total of 67 books and articles were reviewed. Given the rich body of literature, especially in the past centuries, we have come to the conclusion that truffles were well known to the Poles (at least to the nobles and the rich). Some factors determining truffle forgetfulness after the Second World War are given in respect to social, cultural and forests' management changes. The following reasons can be highlighted: (1) changes in the forest cover, which in 1945 was only 20.8% and furthermore unfavorable changes in the forest struc− ture, the tree species composition and the management (undergrowth shading the forest floor) for truffle development; (2) changes in the structure of forest ownership and management, especially disappearance of traditional ways of forest use, such as cattle grazing and brushwood collecting; (3) changes of Polish State borders resulting in significant area of soils, which are conducive to truffles growing (chernozem) coming into the borders of Ukrainian territory; (4) social changes resulted from the extermination and deportations of Polish aristocracy and intelligentsia (including foresters) – knowledgeable social group of people regarding truffle col− lection, use and cultivation as well as migration of people from rural to urban areas and emigra− tion from Poland, and (5) the fact that in time of communists regime there was no room to promote the gourmet products, especially if it was associated with the aristocracy. In consequence, truffles went into oblivion. Furthermore, the aspects of promotion and establishment of truffle orchards in Poland in the last decade are also presented. Based on the authors findings is clearly shown that there is a great potential towards promotion and growing truffles in Poland, especially Tuber aestivum Vittad. known as summer or Burgundy truffle. This species has a wide range in Europe and plasticity to different climatic conditions.

Opis:
Day after day it is being demonstrated that Greece hides a buried treasure in its forests. The wild black truffles Tuber aestivum, T. uncinatum, T. brumale and T. melanosporum and the white truffle T. borchii and recently T. magnatum are picked in a variety of forest ecosystems all over the country. The information which has been collected has initiated a national programme on truffle cultivation which, so far, has immense appeal, especially among young farmers. The discovery of carpophores of T. magnatum, the most valued white truffle in the market, triggered the interest in studying the site characteristics, botanical and pedological, in order to help farmers to cultivate the species in similar sites. All carpophores were found under hornbeam (Carpinus orientalis) along the banks of a creek on alluvial sediment. Soil analyses of four soil samples from truffle nests showed a narrow range of values of pH in water (7.57–7.78) and 1N KCL (6.94–7.07) and a similar granulometric soil texture.

Opis:
The advent of language implementation tools such as PyPy and Truffle/Graal have reinvigorated and broadened interest in topics related to automatic compiler generation and optimization. Given this broader interest, we revisit the Futamura Projections using a novel diagram scheme. Through these diagrams we emphasize the recurring patterns in the Futamura Projections while addressing their complexity and abstract nature. We anticipate that this approach will improve the accessibility of the Futamura Projections and help foster analysis of those new tools through the lens of partial evaluation.

Opis:
The research presented here seeks to describe the impact of wild boar to a natural truffle ground of Tuber aestivum Vittad. on Monte Amiata (Tuscany – Italy). Pedoclimatic analyses indicated that the selected area could be considered suitable for the truffle production. Then classification of the vegetation of a Quercus cerris forest was carried out exploring the possibility of the BACI (Before-After-Control-Impact) sampling design. Finally 10 plots were selected, half of which have been fenced. For the first time the impact of wild boar was evaluated by estimating the surface area turned over by its activity. Moreover in each plot the number and weight of summer truffles was performed every 10 days during the fruiting period (June-November 2006-2008). The hypothesis that the presence of Sus scrofa has a strong negative influence on truffle harvesting has been amply confirmed by the data presented here, given the large increase of fruiting bodies of the summer truffle collected in the fenced plots. Consequently the destructive behaviour of the wild boar imply not only an ecological but also an economic damage in areas in which non-wood forest products are an important source of income.

Opis:
Truffles belong to the hypogeous fungi living in ectomycorrhizal symbiosis with many forest tree and shrub species. Some truffle species such as black truffle (Tuber melanosporum Vittad.) or summer truffle (Tuber aestivum Vittad.) are valuated for their smell and special taste. The confirmed occurrence of summer truffles in Poland may lead to a conclusion that cultivation of this species under Polish conditions might become an alternative to traditional truffle cultivation regions. This is of particular importance given that, in the Mediterranean countries with climate disturbances, the number of truffle fruiting bodies declines while the demand for them grows continuously. In addition to their economic value for producers, establishing truffle orchards is also beneficial with regard to nature protection. The paper presents soil and climate requirements of the summer truffle and the indispensable conditions for establishing so called "truffle orchards".

Opis:
This article highlights historical data regarding truffles’ occurrence in Poland. Along with the soil parameters the plant communities at the sites were studied. The results of the chemical soil analyses showed that the soil water pH at 5 sites was acidic (from 4.3 to 6.1), and only in one, Wiązowna, was the pH (7.2) conductive to truffle development. Similarly, the content of calcium carbonate (CaCO3) in soil samples was low (from 0 to 0.03 %), except for Wiązowna, where CaCO3 was 0.12 %. Among the 24 reported species of trees and shrubs, 7 species were hostplants of summer truffle (Tuber aestivum Vitt.). Out of these 7 species, oak and hornbeam were present at four locations. Across the sites, 31 species of ground-layer plants were identified. Among these, Epipactis helleborine was only one host-species of summer truffle. Our findings indicate that the formation of truffle fruiting-bodies depends on specific habitat characteristics. The key factors determining this process are soil parameters, such as: texture, pH and calcium content. Our inventory showed that the sites we studied still persist as natural stands, although only one of them seems to be favorable for truffle development: this site is located in Wi¹zowna, where soil is of pH 7.2 and E. helleborine (host species for truffles from Orchidaceae) is found, fulfills the environmental requirements of truffles.
