Key words: Pairing tests, Phellinus pini group, Porodaedalea, Porodaedalea niemelaei, sequence analysis

Abstract:  Two specimens of Porodaedalea (Phellinus pini group, Basidiomycetes), collected from Larix sibirica in Finland, were compared with the European-based species P. pini and P. chrysoloma, and other taxa originating from North America, Russia, and China. While differentiation based on fruiting-body characters was difficult, pairing tests and sequence data of the nuclear ribosomal ITS region (ITS-1, 5.8S, ITS-2) showed the collections from Larix sibirica to be distinct and they are suggested as a new species, Porodaedalea niemelaei M. Fischer.

Observations on the genus Amaurochaete (Myxomycetes), and a European record of A. trechispora

Key words: Amaurochaete, Stemonitales, Symphytocarpus

Abstract: The borderlines between the genera Amaurochaete, Symphytocarpus and Stemonitis pose taxonomic and nomenclatural questions due to the limited amount of type material and the variability of the species involved. Details in spore ornamentation lend strong support to the notion that Amaurochaete ferruginea and Stemonitis splendens var. flaccida are conspecific. The ornamentation consists of evenly distributed short-cylindrical processes with rounded tips, and the wall of the spore body has numerous pores 25-30 run wide. Amaurochaete atra, A. tubulina, and A. comata all appear to be more or less restricted to coniferous wood as a substratum. The vast majority of the first two species have been found on wood and bark of Pinus, whereas the much rarer A. comata so far has been recorded on Abies, Picea, and Tsuga. Amaurochaete trechispora is an oddity in the genus, differing in its reticulate-ornamented spores and growing on Sphagnum mats in bogs. A specimen from Sweden is the first record of this species outside North America. A specimen from France with spore ornamentation consisting of pillarshaped papillae with swollen tips may represent an undescribed species of Amaurochaete.

Key words: Basidiomycota, checklist, Northeast China, polypores, taxonomy

Abstract:  This paper summarizes the polypores (Basidiomycota) recorded during the investigations made by the author in 1993- 1999 in northeastern China. The study is based on ca. 2500 specimens collected, but additional data was obtained from the critical reexamination of the previously collected herbarium material. Altogether 261 polypore species were recorded from the study area and are listed here. Fifteen species are new to China. In addition, nine species found in the Russian Far East are included. The checklist provides a taxonomically sound basis for future studies on poroid woodinhabiting fungi in the area. Taxonomy of some noteworthy species is outlined, and the following new combinations are proposed: Inocutis levis (P. Karst.) Y.C. Dai, Inonotopsis exilispora (Y.C. Dai & Niemelä) Y.C. Dai, and Trichaptum polycystidiatum (Pilát) Y.C. Dai.

Key words: mycologist, polypore, teacher, Tuomo Niemelä

Abstract:  Tuomo Niemelä (born 25.V.1940), one of the leading mycologists in Finland, is internationally best known for his studies on polypore systematics. His good taxonomic eye and excellent illustrations are highly appreciated among the world’s aphyllophorologists. In Finland, most biology students know him as a brilliant university teacher with a delicate sense of humour. His research topics include the ecology and systematics of wood-decaying fungi, the vegetation and plant geography of East Africa, and inflorescence structures and morphological adaptation of vascular plants.
