“…In agreement with Shimono et al (2007), we observed that pileus colour supports the delimitation of at least some phylogenetic species. However, infraspecific variability can be high, or the same pileus colour can be observed in several species.…”

“…To investigate conspecificity between the Thai, Japanese and Chinese L. volemus, we constructed a ML phylogram based on our LSU data set, augmented with the LSU sequences produced by Shimono et al (2007) (results not shown). The Japanese 'velvet type' and 'common form' of L. volemus are so far not recorded from northern Thailand.…”

“…This analysis was performed on all four data sets (LSU, ITS, rpb2 and combined) and will be further referred to as the ML analysis. An additional ML analysis was performed on the LSU data set augmented with the 2 Chinese and 19 Japanese L. volemus LSU sequences from Shimono et al (2007) (GenBank accession no. AB238645-AB238665).…”

“…Although L. volemus is morphologically well-characterized, a substantial amount of variation in colour, lamellae spacing and habit has been recorded and it is therefore considered as a putatively unresolved worldwide species complex Shimono et al 2007;Wang 2007). This variation has led to the description of ten different varieties to which, in general, no taxonomical importance seems to be attributed (Bouchet 1959;Dörfelt et al 2004;Fries 1838;Heim 1962;Hesler and Smith 1979;Maire 1937;Neuhoff 1956;Peck 1885).…”

“…Recently, Shimono et al (2007) examined the L. volemus species complex in Japan, where three macromorphological variants of the common brown coloured L. volemus have been observed, i.e., a variant with red pileus, one with a yellow pileus and long stipe, and one with a conspicuously velvety surface texture. Using nuclear LSU sequence data, they distinguished four genetically isolated clades.…”

Lactarius volemus sensu lato (Russulales) from northern Thailand: morphological and phylogenetic species concepts explored

et al. 2010

Lactarius volemus (Fr.: Fr.) Fr. is a well known and morphologically easily recognizable milkcap of the Northern hemisphere, forming ectomycorrhiza with both deciduous and coniferous trees. It was originally described from Europe, but is also reported in other continents. Although it is characterized by several unique macro- and micromorphological features, substantial variation in colour, lamellae spacing and changing and staining of the latex has been recorded and it is therefore considered as a putatively unresolved species complex. This study explores the concordance between morphological and phylogenetic species concepts within L. volemus sensu lato of northern Thailand, combining a critical morphological scrutiny with a multiple gene genealogy based on LSU, ITS and rpb2 nuclear sequences. Twelve strongly supported monophyletic clades and six terminal branches are discernable in all phylogenetic trees and represent 18 phylogenetic species. Six of the monophyletic clades can be morphologically distinguished and are described as new species: L. acicularis, L. crocatus, L. distantifolius, L. longipilus, L. pinguis and L. vitellinus. Five other clades also show some morphological differences, but these are too subtle and do not allow for a clear-cut species delimitation without the corroboration of molecular data. Lactarius volemus sensu lato of northern Thailand is therefore still considered as a partially cryptic species complex. Pleurolamprocystidia, pileipellis hairs and to a lesser degree also pileus colour are important diagnostic characteristics. Spore morphology, latex discoloration and pileus surface texture are less useful as diagnostic features. Whether this rich diversity is the result of in situ Pleistocene survival or post-glacial expansion and subsequent radiation, has yet to be revealed

Huotanjun (Burnt Charcoal Mushroom) is a group of edible mushrooms widely hunted and eaten in southern China.Taxonomically they belong to Russula sect. Nigricantinae. Confusion with the fatal R. subnigricans cause many poisoning incidents in Asia. For a long time, European names were used in Asia but the Asian genotypes are not the same as European species. We studied specimens collected from markets and the eld in southern China. Analysis of four DNA loci (ITS, nc LSU, TEF1-α, RPB2) showed that except for a specimen of R. adusta from subalpine Abies forest in southwestern China, all the specimens represent species different from European and North American ones, suggesting prevalent continental endemism in this group. Four new species were described. Among them R. sinoadusta and R. zhuzuijun are Asian counterparts of R. adusta; R. brunneocystidia and R. huotanjun are closely related with European R. densifolia and R. fuliginosa. These species are highly similar to their European siblings and the morphological differences are very subtle. Using multi-locus data, for the rst time, we determined the phylogenetic position of R. subnigricans. It was nested in R. sect. Nigricantinae and sister to R. latolamellata, a species also having distant lamellae and only reddening context. Geographically except for R. sinoadusta known only from China, all species are shared by China and Japan. We analyzed presence/absence of the diagnostic toxin of R. subnigricans cycloprop-2-ene carboxylic acid for 12 species and did not detect the polymeric products in any of them but R. subnigricans. Nevertheless, considering several potentially edible species also have spaced lamellae and only reddening discolouration which can be easily confused with R. subnigricans, we strongly recommend to only eat species with decidedly blackening context and gills.
