Two new Laccaria species from China based on molecular and morphological evidence

Morphology and Molecular Phylogeny Reveal Five New Species of Laccaria (Hydnangiaceae, Agaricales) from Southern China

“…Guangdong Province, Shaoguan City, Ruyuan County, Nanling National Nature Reserve, 24 • Kost are similar to L. nanlingensis. However, L. fagacicola differs from L. nanlingensis by its brownish orange to brownish pileus, relatively larger basidiospores (7-9 × 6.5-8 µm) and basidia (45-60 × 9-12 µm) [2]. Laccaria himalayensis differs by its larger basidiospores (av.…”

“…Redhead & A.H. Sm. was selected as the outgroup based on recent studies [2,33]. The phylogeny tree derived from the ML analysis with both PP and BS support values is shown in Figure 1.…”

“…& Broome (Agaricales, Hydnangiaceae) is an important fungal group with high ecological and economic values. Species in Laccaria are widely reported from every continent except Antarctica and can form ectomycorrhizal (ECM) relationships with a wide range of trees, such as Betulaceae, Fagaceae, Myrtaceae, Pinaceae and Salicaceae [1,2]. Laccaria is considered a model genus for understanding ectomycorrhizal (ECM) ecology and evolution; some species are reported that can act as pioneer species and can be frequently found in recently disturbed sites and young forest stands, play important roles in primary and secondary succession, and are useful for ecological protection and restoration [1,[3][4][5][6][7][8][9][10][11].…”

“…It is not difficult to recognize the genus Laccaria due to its distinct morphological characteristics; however, infrageneric species identification is difficult in many instances due to the overlapping morphological features [18][19][20]. Recent studies show that molecular data are helpful in species identification of this genus [1,2,17,18,[20][21][22]. The discovery of Laccaria new species has been rapidly increasing in recent years [23].…”

“…The discovery of Laccaria new species has been rapidly increasing in recent years [23]. To date, about 110 species have been reported worldwide [2,23], but most of them were originally described from Europe and North America [1,8,20,[24][25][26][27][28][29]. In China, 25 Laccaria species have been reported, including 17 species originally described from China [1,2,17,22,[30][31][32][33][34].…”
