Specimens of the genus Amanita collected from Japan and deposited in the herbarium of the Department of Botany, National Science Museum, Tsukuba, Ibaraki, Japan (TNS) were studied. Eighteen taxa, including two species new to science and two taxa new to Japan are reported here. Brief notes on a few type specimens of the Amanitae described by T. Hongo are also included in the present accunt. The new species are Amanita orientogemmata and A. oberwinklerana, while the new records are A. manginiana sensu Chiu and A. subjunquillea var. alba. Amanita sphaerobulbosa is treated as a distinct species, independent of A. abrupta.

As a result of the examination of 26 interspecific mixtures of 12 dictyostelid species, 12 mixtures showed some irregular phenomena among aggregating pseudoplasmodia. In 6 of them, including a mixture of Polysphondylium pallidum and P. violaceum, mutually overlapping pseudoplasmodia were found. In other 3,including a mixture of Dictyostelium delicatum and D. minutum, secondary pseudoplasmodia of D. minutum were sometimes observed to overlap the pseudoplasmodia of counterpart species. In the other 3 mixtures, i.e., Acytostelium sp.-1 and A. sp.-2,D. delicatum and P. violaceum, and D. microsporum and P. violaceum, abnormal pseudoplasmodia composed by the pairs were found. Such abnormal pseudoplasmodia were found in the mixture of D. delicatum and D. minutum besides overlapping pseudoplasmodia. These findings suggest that 1) P. pallidum may respond to a chemical substance different from the acrasin of P. violaceum, 2) the acrasin of D. delicatum, D. microsporum and D. minutum may be identical with or closely related to that of P. violaceum, and 3) in D. minutum, the acrasin promoting the primary pseudoplasmodia may differ from the chemical substance conducting the secondary ones.

Halophila japonica sp. nov. is described from Japan. Although this entity has long been referred to as H. ovalis, data obtained from detailed morphological examination of field collections and herbarium specimens, geographical distribution records and ITS sequence analyses demonstrate that it is distinguishable from all other members of this genus and can be recognized as a new species. H. japonica is presently reported to occur from Ibusuki (Kagoshima Prefecture, Kyushu region, Japan) in the south, to Mutsu Bay (Aomori Prefecture, Honshu region, Japan) in the north. In order to better characterize H. ovalis materials from Japan, some observations on this species were also provided. As an outcome of this study, there are now four species of Halophila known from Japan: H. ovalis, H. euphlebia, H. decipiens and H. japonica.

Full description based on fertile specimens is given to Ramalina hossei VAIN., which has long been overlooked by lichenologists. Variation of secondary products of the species is also discussed.

Molecular phylogenetic analyses using two data sets, derived from DNA sequences of matK, the maturase-encoding gene located in an intron of the chloroplast gene trnK, and ITS (internal transcribed spacer) region of the 18S-26S nuclear ribosomal DNA, were performed to examine relationships among 37 taxa in Cymbidium. Although each data set did not provide conclusive evidence in itself, the data sets combining the two regions yielded the following insights: (1) Cymbidium subgenus Cyperorchis and section Pachyrhizanthe, often treated as independent genera, were nested within the remaining members of Cymbidium. (2) All the three subgenera of Cymbidium, namely, Cymbidium, Cyperorchis, and Jensoa, turned to be para-/polyphyletic. (3) Among sections of Cymbidium, Austrocymbidium, Cyperorchis, Iridorchis, and Maxillarianthe did not show monophyly. (4) At specific level, our results indicated the polyphyly of Cymbidium bicolor, although bootstrap supports for the clades including C. bicolor were not robust.

Swertia japonica (Schult.) Makino var. latifolia Konta is a new variety characterized by broader leaves than those of typical variety of Swertiajaponica (Schult.) Makino. This variety was discovered in Mt. Mihara-yama in Hachijo Island, Tokyo, Japan. Several specimens cited in this paper suggest that this variety is distributed in the Izu Islands as well as Honshu, mainland of Japan.

The taxonomy of Vernonia sects. Xipholepis and Claotrachelus was examined. Six species of sect. Xipholepis and one of sect. Claotrachelus are enumerated in this paper. Of them, three species are described as new to science from Thailand and one species is newly recorded from Thailand. The chromosome number is reported of four species in this paper: Vernonia doichangensis 2n=54, V. ngaoensis 2n=36, V. silhetensis var. subserrata 2n=54 and V. squarrosa var. orientalis 2n=18.

Podostroma daisenense DOI et UCHIYAMA, sp. nov. was found from Mt. Houki-Daisen, Tottori Pref., Japan. This species is related to P.africanum BOEDIJN in the morphology of stroma and partspore, but it differes from the latter mainly in much smaller partspores, perithecial and hyphae of stromal tissue.

Eight species of the genus Pertusaria in the family Pertusariaceae are reported from the Cheju Island in Korea. Among them four species are newly recorded for the Korean lichen flora. P. coreana Rasanen is reduced to a synonym of P. astomoides Nyl. The presence of pseudocyphellae is reported in P. laeviganda and P. sublaevigand. An artificial key for all species of the genus known to occur in Korea is provided.
