“…In conjunction with other inventories, our data suggest that tropical forest EM fungal communities can be as species-rich as those found in temperate forests (i.e., Smith et al 2011;Henkel et al 2012;Diédhiou et al 2014). A comparison of EM fungal diversity in root tips using Fisher's alpha showed no significant difference between temperate forests (mean Fisher's alpha=46.87, SD = 55.23) and tropical forests studied thus far (mean Fisher's alpha=47.06, SD=52.65; F<0.001, df=1, 46, P= 0.992).…”

“…All of the major EM fungal clades sensu Tedersoo et al (2010b) encountered in this study have been reported previously in both temperate and tropical EM fungi inventories (Peay et al 2010;Smith et al 2011;Tedersoo et al 2011;Phosri et al 2012;Diédhiou et al 2014). Members of the /russula-lactarius, / cortinarius, and /tomentella-thelephora lineages were particularly abundant, accounting for 72 % of OTUs.…”

“…Members of the /russula-lactarius, / cortinarius, and /tomentella-thelephora lineages were particularly abundant, accounting for 72 % of OTUs. An overall dominance by Russula has been found in other above-and belowground EM fungal inventories in tropical forests (Peay et al 2010;Smith et al 2011;Tedersoo et al 2011;Henkel et al 2012;Phosri et al 2012;Diédhiou et al 2014), suggesting that this is an important taxonomic group to focus on in future biogeographic and systematics-based studies.…”

“…To explore broader patterns of EM fungal diversity, we compiled records from EM fungal inventories of temperate and tropical forests, including studies reviewed by Tedersoo et al (2012) and three more recent studies by Diédhiou et al (2014), Smith et al (2013), and Kennedy et al (2012). We calculated diversity for data presented in each study using Fisher's alpha, which is robust to differences in sample size, and compared temperate versus tropical forests using a oneway ANOVA.…”

“…It is noted by Boa (2004) that the countries on the continent with a better coverage of reports of edible fungi use are Morocco, Cameroon, Nigeria, Democratic Republic of the Congo, Kenya, Zambia, Zimbabwe and South Africa. Also, great progress in ethnomycological knowledge has been made in Benin, Togo, Burkina Faso and Gabon (Yorou et al 2014). The poor quality of identification and documentation of edible and medicinal fungal and lichen species has led to inconsistencies in data on their use in folk medicine, nutrition and mythological beliefs.…”

Africa is an important global reservoir for biological, cultural and traditional knowledge about fungi and lichens, which are used as food, medicine and in mythology, among other things. African human populations are undergoing highly significant changes and adaptation processes, which are accompanied by rapid urbanization, meeting with western civilization, high rural migration and the loss of natural ecosystems. Indigenous knowledge is being lost, including that concerning fungi and lichens. Ethnomycology and ethnolichenology provide a diversity of knowledge about beneficial and poisonous fungi and lichens, and give insights into their sociological impact on human behaviour and use. Here we present a working and publishing environment established with the Diversity Workbench software in line with national and international initiatives for FAIR guided provision of research data. The database application called ‘EthnoMycAfrica’ contains published ethnomycological and ethnolichenological information from Africa. The content is created and curated by team partners from Central, East, West, North and Southern Africa. Data entry is performed both online and offline, optionally via a mobile device. Currently, the system with the tools DiversityDescriptions and DiversityNaviKey contains a total of 1350 well-structured and freely and openly accessible data records. EthnoMycAfrica is the first database with a data schema, standard descriptors and data content created mainly by African scholars. The data can be useful for researchers, students, conservationists, policy makers, and others. It will also provide a basis for facilitating hypothesis generation and meta-analysis.

New Neotropical Sebacinales Species from a Pakaraimaea dipterocarpacea Forest in the Guayana Region, Southern Venezuela: Structural Diversity and Phylogeography

Pakaraimaea dipterocarpacea, a member of the Dipterocarpaceae endemic in the Guayana region, is associated with a diverse community of ectomycorrhizal (ECM) fungi. Amongst the 41 ECM fungal species detected in a 400 m2 P. dipterocarpacea ssp. nitida plot in Southern Venezuela, three species belonged to the Sebacinales. We tested whether ECM anatomotype characterization can be used as a feasible element in an integrative taxonomy in this diverse fungal group, where the relevance of fruitbody morphology for species delimitation seems limited. Using a combination of ECM morpho-anatomical characterizations and phylogenetic analyses based on nuclear ITS and LSU sequences, we report three new species. The main distinguishing features of Sebacina guayanensis are the yellowish cell walls together with conspicuous undifferentiated, uniform compact (type B) rhizomorphs. Staghorn-like hyphae are characteristic of S. tomentosa. The combination of clusters of thick-walled emanating hyphae, including hyphae similar to awl-shaped cystidia with basal dichotomous or trichotomous ramifications, and the presence of type B rhizomorphs were characteristic of a third, yet unnamed species. The three species belong to three different, possibly specifically tropical clades in Sebacinales Group A. The geographic distribution of phylogenetically related strains was wide, including a Dicymbe forest in Guyana and an Ecuadorian rainforest with Coccoloba species. We show that ECM morpho-anatomy can be used, in combination with other analyses, to delineate species within Sebacinales Group A. In addition to phylogenetic information, type B rhizomorphs observed in different Sebacinales clades have important ecological implications for this fungal group. The phylogeography of Sebacinales suggests that dispersion and host jump are important radiation mechanisms that shaped P. dipterocarpacea ECM fungal community. This study emphasizes the need for more sequence data to evaluate the hypothesis that phylogeographic relationships between neo- and paleotropical ECM fungal species could be attributed to the vicariance of cross-continental hosts such as the Dipterocarpacae.
