“…Screening of taxa used in the phylogenetic analysis for a large dataset Species belonging to Strobilomyces have been reported from the temperate and subtropical areas of East Asia, North and Central America, Europe and Australia, and the tropical areas of Southeast Asia (Pegler & Young, 1981;Sato et al, 2007), whereas those belonging to Afroboletus, a sister group of Strobilomyces, have been reported from the tropical areas of Africa (Nuhn et al, 2013;Wu et al, 2014).…”

Mutualisms with new host lineages can provide symbionts with novel ecological opportunities to expand their geographical distribution, thereby leading to evolutionary diversification. Because ectomycorrhizal (ECM) fungi provide ideal opportunities to test the relationship between host shifts and diversification, we tested whether mutualism with new host lineages could increase the diversification rates of ECM fungi. Using a Bayesian tree inferred from 23 027-base nucleotide sequences of 80 single-copy genes, we tested whether the diversification rate had changed through host-shift events in the monophyletic clade containing the ECM fungal genera Strobilomyces and Afroboletus. The results indicated that these fungi were initially associated with Caesalpinioideae/Monotoideae in Africa, acquired associations with Dipterocarpoideae in tropical Asia, and then switched to Fagaceae/Pinaceae and Nothofagaceae/Eucalyptus. Fungal lineages associated with Fagaceae/Pinaceae were inferred to have approximately four-fold and two-fold greater diversification rates than those associated with Caesalpinioideae/Monotoideae and Dipterocarpoideae or Nothofagaceae/Eucalyptus, respectively. Moreover, the diversification rate shift was inferred to follow the host shift to Fagaceae/Pinaceae. Our study suggests that host-shift events, particularly those occurring with respect to Fagaceae/Pinaceae, can provide ecological opportunities for the rapid diversification of Strobilomyces-Afroboletus. Although further studies are needed for generalization, we propose a possible diversification scenario of ECM fungi.

“…Tylopilus s.l. appeared as polyphyletic and evolved in 11 different lineages during the course of evolution (Nuhn et al 2013, Wu et al 2014). Thus, taxonomic placement of the members of this genus are still floating and many previously considered Tylopilus species are shifted into new genera such as Zangia Yan C. Li & Zhu L. Yang, Australopilus Halling & Fechner and Harrya Halling, Nuhn & Osmundson (Li et al 2011, Halling et al 2012).…”

Tylopilus himalayanus and T. pseudoballoui are described as new species from two Himalayan states (Sikkim and Uttarakhand) in India. Tylopilus himalayanus is characterised by a unique combination of features: reddish- or brownish-grey to purplish-grey then brown to reddish-brown or darker pileus, absence of olive or violet tinges on stipe surface, angular pores, stipe without reticulum or rarely with a faint reticulum restricted to the very apex, bitter taste of the context and positive macrochemical colour reaction of the stipe context with KOH (dark orange) and FeSO4 (dark green), medium sized (10.9–14.4 × 3.9–4.9 µm) basidiospores and occurrence under coniferous trees; T. pseudoballoui is distinguished by orange-yellow to brown-yellow sticky pileus, pale yellow pore surface with pinkish hues that turns pale to greyish-orange on bruising; angular pores, stipe concolorous to pileus with pruinose but never reticulate surface, ixocutis pattern of pileipellis and occurrence under broadleaf trees. Another species, T. neofelleus, which was reported earlier from China and Japan, was also collected from Sikkim and reported for the first time from India. All three species are described with morphological details and two-locus based (nrLSU and nrITS) phylogenetic data.

“…The final dataset consisted of 304 sequences representing species from infrafamilial clades across the Boletaceae based on recent studies (e.g. Nuhn et al 2013, Wu et al 2014, 2015, Smith et al 2015, Henkel et al 2016) and outgroup taxa. Representatives from all available sequestrate Boletaceae genera were included: Castellanea , Chamonixia , Costatisporus , Durianella , Gymnogaster , Heliogaster , Jimtrappea , Mackintoshia , Mycoamaranthus, Neoboletus , Octaviania, Rossbeevera, Royoungia , Solioccasus, and Spongiforma .…”

Kombocles bakaiana gen. sp. nov. (Boletaceae), a new sequestrate fungus from Cameroon

et al. 2016

View full text Add to dashboard Cite

Kombocles bakaiana gen. sp. nov. is described as new to science. This sequestrate, partially hypogeous fungus was collected around and within the stilt root system of an ectomycorrhizal (ECM) tree of the genus Uapaca (Phyllanthaceae) in a Guineo-Congolian mixed tropical rainforest in Cameroon. Molecular data place this fungus in Boletaceae (Boletales, Agaricomycetes, Basidiomycota) with no clear relationship to previously described taxa within the family. Macro- and micromorphological characters, habitat, and DNA sequence data are provided. Unique morphological features and a molecular phylogenetic analysis of 304 sequences across the Boletales justify the recognition of the new taxa. Kombocles bakaiana is the fourth sequestrate Boletaceae described from the greater African tropics, and the first to be described from Cameroon.
