Abstract: | Host-recurrence of wood-decaying polypores has been substantiated and some species of the class Dacrymycetes, consisting of wood-decaying jelly fungi, occur recurrently on coniferous and broad-leaved tree wood. However, there has been no quantitative analysis for Dacrymycetes. To evaluate their host-recurrence, the fruit body occurrence of Dacrymycetes was investigated at 60 sites, including 13 core sampling sites. A total of 577 samples of 28 species were collected. Principal component analysis revealed characteristic communities on conifers and broad-leaved trees. Binomial tests showed that 12 and four Dacrymycetes species occurred significantly more frequently on conifers and broad-leaved trees, respectively. Of these host-recurrent species, eight and two species exclusively occurred on conifers and broad-leaved trees, respectively, suggesting that some Dacrymycetes species have a strict host-recurrence on these tree groups. |
