Abstract
ABSTRACTNon-lichenised fungi from Fagus crenata, an endemic and major temperate tree species, were enumerated based on three approaches: fungarium specimens at the National Museum of Nature and Science; isolates obtained mainly from leaves and roots, and their molecular identification by barcoding region; and literature. In total, 209, 49, and 232 taxa were recognised from the fungarium specimens, isolates, and literature, respectively. Only three taxa were commonly observed using all three approaches. Moreover, the results demonstrate the diversity of fungi occurring on a single host plant species, and provide the basis for comparisons between fungi from Fagus spp. in other regions of the world.
Highlights
The genus Fagus comprises 10 species and is distributed only in the Northern Hemisphere, with disjunct distribution in Europe, North America, and Asia
770 specimens occurring on F. crenata were found in the fungarium
The present study provides the first cumulated list of species occurring on F. crenata, and allows further comparison with other hosts including other Fagus species across the world
Summary
The genus Fagus comprises 10 species and is distributed only in the Northern Hemisphere, with disjunct distribution in Europe, North America, and Asia. In Japan, Fagus crenata Blume (Japanese beech) is one of the major deciduous arboreal vegetation in the temperate zone. Some other Fagus species are dominant in Europe (F. sylvatica) and America (F. americana). Owing to their importance in vegetation, significant numbers of mycological studies have been conducted in Fagus forests (Carré 1964; Hogg 1966; Hogg and Hudson 1966; Yamashita et al 2010; Unterseher et al 2016). Fagus crenata is an endemic tree species in Japan, forming climax forests. Because of its dominance in Japanese flora and owing to interest in phylogeography and conservation biology, a number of studies have been conducted on F. crenata (Kurata 1964; Horikawa 1972; Tsukada 1982; Murai et al 1991; Fujii et al 2002; Terazawa and Koyama 2008)
