Hydnum berkeleyanum K. Das, Hembrom, Baghela & Vizzini 2018

Hydnum berkeleyanum K. Das, Hembrom, Baghela & Vizzini, 2018 Fig. 5 A – E Habitat and distribution. The species grows gregariously in a Q. serrata forest within the core zone of Tianma National Nature Reserve, China (ca. 1000–1100 m, subtropical monsoon climate). It is currently known from India, Pakistan, Anhui Province, and Yunnan Province in China. The specimen was collected at a distance of 105.6 cm from a Q. serrata tree (DBH: 56.8 cm). Soil temperature was 20.6 ° C, soil volumetric water content was 17.5 %, soil pH was 5.9, air temperature was 23.2 ° C, and relative humidity was 91.2 %. Soil temperature, moisture content, and pH were measured at the time of sample collection; air temperature and humidity were monitored over the long term within the sample plot (measurements were taken at 10 - minute intervals; these data are mean values calculated over the 3 days preceding and following sample collection). Specimens examined. China • Anhui Province, Lu’an City, Tianma National Nature Reserve, 31°15'20"N, 115°42'09"E, Elevation: ca. 1049 m, 23 July 2023, Yonglan Tuo (FJAU 66576), GenBank accession numbers: ITS = PV 875855, tef 1-α = PV 889364); • Anhui Province, Lu’an City, Tianma National Nature Reserve, 31°15'21"N, 115°42'07"E, Elevation: ca. 1052 m, 16 July 2023, Yonglan Tuo (FJAU 66577), GenBank accession numbers: ITS = PV 875856, tef 1-α = PV 889365. Notes. No major differences were found between our specimens and the type; however, the habitat of our specimens (Q. serrata forest) differs from that in the original description (mixed forest). Phylogenetic analyses based on multi-marker datasets indicate that the two specimens from Anhui are well nested within the H. berkeleyanum clade.
