“…Curtis) Murrill. Based on molecular data, Raspé et al (2016) stated that what is called Pulveroboletusravenelii outside North America belongs to a complex of different taxa. The name P.ravenelii has been used erroneously for lookalikes in Asia, Australia (Watling 2001, Horak 2011) and also Africa (Thoen and Ducousso 1989, Watling and Turnbull 1992, De Kesel et al 2002, Yorou and De Kesel 2011, Vanié-Léabo et al 2017, Kamou et al 2017).…”

So far, Raspé et al (2016) and Zeng et al (2017) have resolved part of the Asian complex around P.ravenelii , which now counts ten species. In a similar way, this paper aims to resolve and clarify the identity of some of the African, non-viscid, Pulveroboletus that have been kept under “Pulveroboletusaff.ravenelii”.…”

This paper sorts out the taxonomy of species affiliated with Pulveroboletusravenelii in the Guineo-soudanian and Zambezian woodlands of Africa. Morphological and genetic characters of African Pulveroboletus collections were studied and compared to those of North American and Asian species. A phylogenetic analysis showed that the African specimens form a subclade, sister to the Asian and American taxa. Although clamp connections have previously never been reported from Pulveroboletus, all specimens of the African subclade show very small clamp connections. Two new African species, Pulveroboletusafricanussp. nov. and P.sokponianussp. nov., are described and illustrated. Comments concerning morphology and identification, as well as distribution and ecology, are given for both species.

“…The genes atp 6, tef 1 and rpb 2 were amplified by polymerase chain reaction ( PCR ) technique. For the amplification of atp 6, ATP6-1M40F and ATP6-2Mprimers were used ( Raspé et al 2016 ), with the following PCR programme: 2 min at 95 °C; 5 cycles of 45 s at 95 °C, 60 s at 42 °C, 30 s at 72 °C; 35 cycles of 20 s at 95 °C, 30 s at 55 °C, 30 s+1 s/cycle at 72 °C; 3 min at 72 °C. The primers EF1-983F and EF1-2218R ( Rehner and Buckley 2005 ) were used to amplify tef 1 and bRPB2-6F and bRPB2-7.1R primers ( Matheny 2005 ) were used to amplify rpb 2.…”

“… Boletaceae diversity seems to be high in Thailand ( Chandrasrikul et al 2011 ), with several new species described in the last five years ( Choeyklin et al 2012 , Halling et al 2014 , Neves et al 2012 , Raspé et al 2016 ). During this survey of Boletaceae diversity in Thailand, several Rhodactina collections were made and their morphology and phylogenetic relationships were studied.…”

“…During this survey of Boletaceae diversity in Thailand, several Rhodactina collections were made and their morphology and phylogenetic relationships were studied. Phylogenetic analyses were based on three genes: atp 6, tef 1 and rpb 2, which have previously been justified as useful for phylogenetic analyses of Boletales ( Kretzer and Bruns 1999 , Binder and Hibbett 2006 , Hosen et al 2013 , Li et al 2014 , Smith et al 2015 , Orihara et al 2016 , Raspé et al 2016 , Wu et al 2016 ). Both morphology and phylogenetic analyses confirmed that all newly collected specimens belong to a new species in the genus Rhodactina .…”

Rhodactina is a small sequestrate genus in Boletaceae with two described species, R. himalayensis and R. incarnata. Phylogenetic analyses of a three-gene dataset including atp6, tef1 and rpb2 of Rhodactina species along with selected Boletaceae species showed that all Rhodactina species formed a monophyletic clade, sister to the genera Spongiforma and Borofutus in subfamily Leccinoideae with high support. All of the taxa in the clade have a similar chemical reaction in which basidiospores turn purplish, purplish red to violet or violet grey when in contact with potassium hydroxide. The molecular analyses also showed that all Rhodactina specimens collected from Ubon Ratchathani province, northeastern Thailand, belong to a new species. Morphologically, the new species is different from others by having a markedly prominent hilar appendage and a terminal hilum on its basidiospores. Thus, the new species, Rhodactina rostratispora, is introduced with detailed macroscopic and microscopic descriptions and illustrations.
