A leaf spot and stem dieback disease severely occurred on Japanese spurge Pachysandra terminalis Sieb. et Zucc. in Tokyo Metropolis in 1992. Inoculation with conidia and mycelia of the isolated fungus reproduced the symptoms on its original host. The cαusal fungus was identified as Pseudonectria pachysandricola B.O.Dodge (anamorph Volutella pachysandricola B.O.Dodge) based on morphological characteristics and pathogenicity tests. The fungus grew on PDA plates at3-33℃ with an optimum of 23℃. The growth of fungal mycelia was inhibited with benzoimidazoles or ergosterol biosynthesis on PDA plates at 25℃. This is the first report of P.pachysandricola in Japan.

The taxonomic position of Ramicandelaber, Kickxellales, among other kickxellalean and harpellalean fungi was investigated based on 18S rDNA sequences. Neighbor joining analysis and maximum parsimony analysis showed that Ramicandelaber formed a clade independent from kickxellalean and harpellalean fungi. Ramicandelaber may belong to another order of Kickxellales and Harpellales.

Psathyrella delineata found in Shiga Prefecture and Tokyo is described and illustrated as the first record of the species from japan.

Two species of the genus Oudemansiella, O. japonica and O. hongoi were rediscovered from Japan recently and are reported with their descriptions and illustrations.
