“…This phenomenon is widespread in the genus Lactifluus (e.g. Stubbe et al 2010;Van de Putte et al 2010;Van de Putte 2012;De Crop et al 2014;Van de Putte et al 2016;Delgat et al 2017;De Lange et al 2018). For example, a very similar case to that described in this paper occurs in L. sect.…”

The ectomycorrhizal genus Lactifluus is known to contain many species complexes, consisting of morphologically very similar species, which can be considered cryptic or pseudocryptic. In this paper, a thorough molecular study is performed of the clade around Lactifluus deceptivus (originally described by Peck from North America) or the deceptive milkcaps. Even though most collections were identified as L. deceptivus, the clade is shown to contain at least 15 species, distributed across Asia and America, indicating that the L. deceptivus clade represents a species complex. These species are morphologically very similar and are characterized by a tomentose pileus with thinwalled hyphae and a velvety stipe with thick-walled hyphae. An ITS1 sequence was obtained through Illumina sequencing for the lectotype of L. deceptivus, dating from 1885, revealing which clade represents the true L. deceptivus. In addition, it is shown that three other described species also belong to the L. deceptivus clade: L. arcuatus, L. caeruleitinctus and L. mordax, and molecularly confirmed that L. tomentoso-marginatus represents a synonym of L. deceptivus. Furthermore, two new Neotropical species are described: Lactifluus hallingii and L. domingensis.

“…Lactifluussect.Xerampelini is exclusively known from Africa and contains six described species (Fig. 5): L.goossensiae (Beeli) Verbeken, L.kivuensis (Verbeken) Verbeken, L.persicinus Delgat & De Crop, L.pseudovolemus (R.

“…Uapaca species mainly occur mixed with other tree species, whereas G.dewevrei forms more or less monodominant stands, mixed with an occasional Uapaca species. These trees are typical hosts for ECM fungi and Russulaceae have been repeatedly recorded as associated with these trees (Verbeken and Walleyn 2010; De Crop et al 2016; Delgat et al 2017; T.W. Henkel pers.…”

“…The milkcap genus Lactifluus is mainly distributed in the tropics (De Crop et al 2017). It is a species-rich genus with about 160 species distributed worldwide, of which the majority is found in tropical Asia (Le et al 2007b; Stubbe et al 2010; Van de Putte et al 2010), tropical Africa (Van de Putte et al 2009; Verbeken and Walleyn 2010; De Crop et al 2012, 2016; Maba et al 2014, 2015a, b; Delgat et al 2017; De Lange et al 2018) and the Neotropics (Henkel et al 2000; Miller et al 2002; Smith et al 2011; Sá et al 2013; Sá and Wartchow 2013). The genus is relatively understudied and many species remain undescribed due to this mainly tropical distribution.…”

“…Even though this type of cell is frequently present in Lactifluus (pers. observations), these cells are only rarely reported in species descriptions (De Crop et al 2019;Delgat et al 2017), probably often being dismissed as basidioles and/or of limited taxonomic value. This problem presented itself during the description of the two new species and a consensus between the authors of this paper was pursued.…”

Lactifluusrussulisporus Dierickx & De Crop and Lactifluuscaliendrifer Froyen & De Crop are described from eucalypt forests in Queensland, Australia and different forest types in Thailand, respectively. Both species have recently been published on Index Fungorum and fit morphologically and molecularly in L.sect.Luteoli, a section within L.subg.Gymnocarpi that encompasses species with alboochraceous basidiomes, white latex that stains brown and typical capitate elements in the pileipellis and/or marginal cells.
