Hroudová, Z., Zákravsky, P., Duchácek, M. & Marhold, K. 2007: Taxonomy, distribution and ecology of Bolboschoenus in Europe. — Ann. Bot. Fennici 44: 81–102.

The five species of Bolboschoenus — B. glaucus, B. laticarpus, B. maritimus, B. planiculmis and B. yagara — occurring in Europe were studied. A detailed taxonomic and nomenclatural account is provided for these taxa, together with an identification key, distribution data and maps based on a revision of herbarium specimens from 36 herbaria and on field observations. Because ecological differentiation influences the distribution of the taxa concerned, detailed information on their ecology is also provided.

Kotiranta, H., Ushakova, N. & Mukhin, V. A. 2007: Polypore (Aphyllophorales, Basidiomycetes) studies in Russia. 2. Central Ural. — Ann. Bot. Fennici 44: 103–127.

One hundred and sixty-one polypore species are reported from the Central Urals. Two of them, Anomoporia vesiculosa Y.C. Dai & Niemelä and Junghuhnia semisupiniforme (Murr.) Ryvarden, are reported for the first time from Russia. The material consists of literature data and 838 collections and observations, and according to the data of the authors, the most frequent species are Fomitopsis pinicola (Sw. : Fr.) P. Karst., Trichaptum fuscoviolaceum (Ehrenb. : Fr.) Ryvarden, Fomitopsis rosea (Alb. & Schewin. : Fr.) P. Karst., Postia caesia (Schrad. : Fr.) P. Karst., and Bjerkandera adusta (Willd. : Fr.) P. Karst., respectively. These contain 22 per cent of all observations, but only 3.9 per cent of all the species. Thirty-two species (25.2%) were collected only once, 16 species twice (12.6%) and 10 species (7.9%) three times, respectively. The collecting sites are briefly described, the host trees listed and descriptions and illustrations of some species given.

Kotiranta, H., Hjortstam, K., Miettinen, O. & Kulju, M. 2007: Tubulicrinopsis gen. nov. (Basidiomycota, Aphyllophorales) and notes on Amauromyces pallidus. — Ann. Bot. Fennici 44: 128–134.

The genus Tubulicrinopsis Hjortstam & Kotir. is described with three new species, T. ellipsospora Kotir., Hjortstam & Kulju, T. granulosa Hjortstam, Miettinen & Kotir. and T. cystidiata Kotir. & Miettinen, and the new combination T. farinacea (Boid., Lanq. & Gilles) Kotir. & Hjortstam is proposed. Tubulicrinopsis ellipsospora, T. granulosa and T. cystidiata were collected in north European forests and T. farinacea has hitherto been reported from Réunion, Argentina and Taiwan as Amauromyces farinaceus. The species of Tubulicrinopsis are somewhat similar to the species of the genera Tubulicrinis and Sistotremastrum in having thick-walled basidial bases. The type of Amauromyces pallidus Jülich was studied. The species are described and illustrated, and a key to the genus Tubulicrinopsis is given. Botryobasidium ellipsosporum Holubová-Jechová is reported from Finland for the first time.

Dai, Y. C., Yu, C. J. & Wang, H. C. 2007: Polypores from eastern Xizang (Tibet), western China. — Ann. Bot. Fennici 44: 135–145.

A field expedition to study wood-inhabiting fungi in eastern Xizang Autonomous Region (Tibet), western China, was made in summer of 2004, and based on materials collected during the expedition and some herbarium specimens 154 poroid aphyllophoraceous fungi were identified. This paper gives a checklist of our results, and most of the species are here reported for the first time from Xizang. Substrates and collecting data of each species are supplied in the checklist. Ceriporiopsis egula C.J. Yu & Y.C. Dai, Heterobasidion linzhiense Y.C. Dai & Korhonen and Polyporus subvarius C.J. Yu & Y.C. Dai are new to science, and illustrated in line drawings. Species diversity of polypores in eastern Xizang is very high. The major component of the eastern Xizang polypore flora is widely distributed circumpolar, temperate and boreal species.

Enroth, J. & Tan, B. C. 2007: Stereophyllum linisii (Stereophyllaceae), a new moss species from the Philippines. — Ann. Bot. Fennici 44: 146–148.

Stereophyllum linisii Enroth & B.C. Tan, sp. nova, is a confirmed generic record for the Philippine moss flora. The new species is described and illustrated in line drawings. It differs from the single widely distributed species in the genus, S. radiculosum (Hook.) Mitt., mainly in the completely smooth laminal cells and especially the distinct marginal limbidium in the leaves, consisting of elongate cells.

de la Estrella, M., Aedo, C. & Mauricio Velayos, M. 2007: Daniellia pilosa comb. & stat. nov. (Leguminosae, Caesalpinioideae). — Ann. Bot. Fennici 44: 149–150.

Daniellia pilosa (J. Léonard) Estrella, comb. & stat. nov. (Leguminosae, Caesalpinioideae) is proposed. This mountain primary forest tree species is endemic to Gabon in Central Africa.

Wang, X. R. & Shang, C. B. 2007: Cerasus hefengensis (Rosaceae), a new species from SW Hubei, China. — Ann. Bot. Fennici 44: 151–152.

Cerasus hefengensis X.R. Wang & C.B. Shang sp. nova (Rosaceae) from SW Hubei, China, is described and illustrated. It is compared with a morphologically similar species.

Wang, K., Fu, D. Z., Zhang, Z. S. & Yang, Y. 2007: Valid publication of the names Viburnum chingii var. impressinervium and V. formosanum var. pubigerum (Adoxaceae). — Ann. Bot. Fennici 44: 153–154.

Viburnum carnosulum var. impressinervium and V. formosanum var. pubigerum, described from China, were not validly published because two type specimens (one fruiting, one flowering) were designated for each of them in the original publication. To enable formal use, the two names are validly published here, the former as V. chingii var. impressinervium.

Yang, H. Q. & Li, D. Z. 2007: Two new combinations in Cephalostachyum (Poaceae: Bambusoideae). — Ann. Bot. Fennici 44: 155–156.

The molecular and micromorphological support for current generic concepts in the subtribe Melocanninae (Poaceae) has made it necessary to propose new combinations in Cephalostachyum. In this article the following two species are transferred from Schizostachyum to Cephalostachyum: Cephalostachyum chinense (Rendle) D.Z. Li & H.Q. Yang comb. nova, and C. sanguineum (W.P. Zhang) D.Z. Li & H.Q. Yang comb. nova, based on basionyms Schizostachyum chinense Rendle and S. sanguineum W.P. Zhang respectively.

Sa, R. 2007: Hedysarum jaxartucirdes (Fabaceae), a new species from Xinjiang, China. — Ann. Bot. Fennici 44: 157–159.

Hedysarum jaxartucirdes Y. Liu ex R. Sa sp. nova (Fabaceae) is described from Xinjiang, China. It belongs to sect. Subacaulia and appears to be close to H. fenganense. The diagnostic characters, as well as a full description and a detailed illustration are provided. The seed ultrastructure was examined by SEM.
