“…Manuscript to be reviewed Cavender-Bares et al 2009;Egli et al 2010;Gomez et al 2012). Our results showed a positive correlation between slope and the number of macromycete species, agreeing with findings by Caiafa et al (2017) in the Costa region of Oaxaca. But understanding how the slope influences macromycete richness can be a difficult task due to the variety of biotic and abiotic factors related to the soil environment.…”

“…In Mexico, at least 371 macromycete species are traditionally consumed, making it the second country with the most species of wild mushrooms used as food, only after China (600 species), and it is the sixth country in the world with the highest number of ethnic groups (Ruan-Soto, Manuscript to be reviewed region in Mexico (Flores-Villela & Gerez 1994), but there is a lack of mycological information for this area (Garibay-Orijel et al 2006). The few studies on macromycetes in Oaxaca have focused on the functional diversity of macrofungal communities in the Costa region (Caiafa et al 2017), taxonomy and traditional use of Psilocybe species in different localities of the state (Guzmán et al 2004;Ramírez-Cruz, Guzmán & Ramírez-Guillen 2006), the traditional use of macrofungi in the Mixteca region (Santiago et al 2016), and the diversity and traditional use of macromycetes in the Sierra Norte region, which has the most complete inventory of useful macromycetes in Mexico, comprising a total of 159 taxa (Garibay-Orijel et al 2009).…”

Wild edible mushrooms have been collected and consumed by human groups for centuries, and today they represent a relevant source of food and income for many rural families worldwide. Preserving these non-timber forest products is of great interest, and there is concern about the damage caused by intensive mushroom harvesting on macromycete communities. The aim of this study was to evaluate variation in diversity and composition of macromycete species between areas regularly used for mushroom harvesting and non-harvested areas in the Mixteca region of Oaxaca, Mexico, as well as to assess the influence of microclimatic and environmental factors on this variation. We selected two harvested and two non-harvested sites within the study area. In each one, we established 10 permanent plots of 10 m x 10 m where we sampled all the observed fruit bodies weekly from June to October 2017. We recorded a total of 856 individuals corresponding to 138 species, and 23 of these were identified as edible. Overall macromycete diversity, edible species diversity and composition were similar in Sites 1(non-harvested) and 3 (harvested), and in Sites 2 (non-harvested) and 4 (harvested). Variation of diversity and species composition along the studied area was mainly related to microclimatic variables, while most environmental variables and variables related to vegetation structure similarly affected macromycete species in the four sites. Our results indicate that intensive harvesting of wild edible mushrooms is not affecting the diversity and distribution of macromycete species in our study area. Knowledge on the sustainability of mushroom harvesting practices can help improve current regulations regarding the management of these valuable non-timber forest products.

“…The composition and distribution of EcM fungal fruiting bodies varied significantly with host tree distribution. In all forest types, the families Russulaceae and Cantharellaceae dominate, as previously reported by Eyi‐Ndong et al ( ) for the Central African rainforests, Buyck, Gomez‐Hernandez, Williams‐Linera, and Ramírez‐Cruz () and Bâ, Duponnois, Moyersoen, and Diédhiou () for the savannah woodlands of Western Africa and Buyck (), Härkönen et al () and De Kesel et al () for the Miombo woodlands. Species of Cantharellaceae and Russulaceae should have developed capacities to adapt to the local edaphic conditions enabling them to successfully colonise plant roots throughout these forest types (Berruti et al, ; Brundrett, ; Burke et al, ).…”

Ectomycorrhizal fungi constitute an important component of forest ecosystems that enhances plant nutrition and resistance against stresses. Diversity of ectomycorrhizal (EcM) fungi is, however, affected by host plant diversity and soil heterogeneity. This study provides information about the influence of host plants and soil resources on the diversity of ectomycorrhizal fungal fruiting bodies from rainforests of the Democratic Republic of the Congo. Based on the presence of fungal fruiting bodies, significant differences in the number of ectomycorrhizal fungi species existed between forest stand types (p < 0.001). The most ectomycorrhizal species‐rich forest was the Gilbertiodendron dewevrei‐dominated forest (61 species). Of all 93 species of ectomycorrhizal fungi, 19 demonstrated a significant indicator value for particular forest stand types. Of all analysed edaphic factors, the percentage of silt particles was the most important parameter influencing EcM fungi host plant tree distribution. Both host trees and edaphic factors strongly affected the distribution and diversity of EcM fungi. EcM fungi may have developed differently their ability to successfully colonise root systems in relation to the availability of nutrients.

“…Detecting and understanding patterns in the distribution of taxa is a major topic in ecological studies and a fundamental element in implementing biodiversity conservation (Gaston, 2000;Purvis and Hector, 2000;Tilman, 2000;Schmit 2005;Caiafa et al, 2017;Dvorack et al, 2017). Regarding fungi, the most important aspect of biodiversity assessment is the measures of species richness (Schmit et al, 1999;Hawksworth, 2001).…”

“…Regarding fungi, the most important aspect of biodiversity assessment is the measures of species richness (Schmit et al, 1999;Hawksworth, 2001). Insight into fungal species richness is vital for biodiversity management, especially when the conservation status needs to be evaluated (Caiafa et al, 2017). Next to a number of classical qualitative and quantitative traits, functional traits are now also being used for evaluation (Caiafa et al, 2017).…”

Detecting and understanding patterns in the distribution of taxa is a fundamental element in implementing biodiversity conservation. Regarding fungi, understanding how functional diversity varies with forest types helps to define their niche and allows predicting the impact of forest degradation on communities of macrofungi. It also allows better understanding of the way in which they realize their ecological function and nourishment purpose. This study aimed to assess the species richness and functional diversity of macrofungi within rainforests from Yangambi Biosphere reserve and Yoko reserve in the Democratic Republic of the Congo. Results from this study show significant differences in number of macrofungi species between forest stand types (p-value<0.001). Based on all macrofungi functional groups, the most species-rich forest stand was the Gilbertiodendron dewevrei. Of the five reported functional groups (saprotrophic fungi, ectomycorrhizal fungi, insect parasitic fungi, plant parasitic fungi and termites' symbiotic fungi), the saprotrophic fungi were the most abundant trophic group represented 210 species of a total of 341 fungal taxa. The results revealed also that woody decaying and terrestrial saprotrophic are mainly characteristic of mixed forests while the occurrence of ectomycorrhizal taxa depends on the presence of ectomycorrhizal trees. In addition, strong relation has been demonstrated between fungal composition and the composition in vascular plants. Each forest stand type is characterized by specific floristic composition which has a corresponding and fairly predictable mycological composition. The study gave evidence that species richness and functional diversity of macrofungi are strongly influenced by vascular plants composition. The various reported functional groups differently intervene in nutrients cycling, and then play key role in forests functioning.
