ABSTRACTS

A SYNOPSIS OF HIERACIUM SECT. CERNUA (ASTERACEAE).

Abstract: Historically, the taxa of the Hieracium sparsum group have been included in several infrageneric taxa. At sectional level, Hieracium sect. Cernua R. Uechtr. has priority over H. sect. Sparsiflora Gus. Schneid. and H. sect. Pseudostenotheca (Fr.) Juxip. Seventy-three species and subspecies are placed in H. sect. Cernua. Hieracium naegelianum Pančić is transferred to the new monotypic sect. Naegeliana Zahn ex Szeląg.

Key words: Asteraceae, Hieracium, sect. Cernua, sect. Naegeliana, taxonomy, nomenclature, distribution

NEW RECORD AND DISTRIBUTION OF MYCENA OREGONENSIS (AGARICALES, BASIDIOMYCETES) IN EUROPE.
Abstract: A new locality of a very rare species, Mycena oregonensis A. H. Sm., is given in Central Europe. This locality, situated in the Tatra Mts, is the first one in Poland and the Carpathians, as well as the most southeastern one known in Europe. The known distribution of the species in Europe is presented on a map.

NOTES ON POLISH POLYPORES. 3. FOUR RARE SPECIES OF OLD-GROWTH FORESTS.

Abstract: Four rare Polish polypores that appear mostly in old-growth forests, Antrodia malicola (Berk. & M. A. Curtis) Donk, Diplomitoporus lindbladii (Berk.) Gilb. & Ryvarden, Pycnoporellus alboluteus (Ellis & Everh.) Kotl. & Pouzar and Pycnoporellus fulgens (Fr.) Donk, are described, illustrated and discussed, to supplement information in the second fascicle of the Atlas of the geographical distribution of fungi in Poland.

MONODOMINANT FORESTS OF AUCOUMEA KLAINEANA AND TERMINALIA SUPERBA IN THE CHAILLU FOREST (SW CONGO, AFRICA).

Abstract: The paper describes the vegetation types observed in the Ngoua 2 Forest. Analysis of floristic composition led to identification of four vegetation types there: monodominant forest of Terminalia superba and of Aucoumea klaineana, mixed forest and swamp forest. Two other vegetation types, secondary forest and riverine forest, exist in the outer fringes of the study site. The collected plants represent 451 species (296 genera, 91 families), of which 436 were identified completely. Nine plant species were added to the flora of the Chaillu Forest. A checklist of the vascular plants collected and identified in the Ngoua 2 Forest is provided.

Key words: Flora, vegetation, Terminalia superba, Aucoumea klaineana, Chaillu Forest, Africa

DYNAMICS OF SPHAGNUM CUSHIONS IN THE WILLOW CARR OF BENCE-TÓ MIRE (NE HUNGARY) AND ITS NATURE CONSERVATION ASPECTS.

Abstract: We studied the dynamics of peat moss cushions in 1994-1997 at the strictly protected willow carr of Bence-tó mire (NE Hungary), where the amount of Sphagnum fimbriatum Wilson subsp. fimbriatum and S. squarrosum Crome has been decreasing from year to year. We recorded the size of 25 selected Sphagnum cushions, the proportion of Sphagnum species making up the cushions, and the vascular plant species found in the cushions. The Sphagnum carpets broke up into smaller cushions, and below a critical size (~660 cm2) the risk of their disappearance was high. The two Sphagnum species disappeared at approximately similar rates, but cushions consisting of both species were more likely to survive than single-species cushions. As their environment became wetter in 1997, the cushions increased in size, but the two Sphagnum species were not able to survive the sudden rise of the water level in 1998. For protection of Hungarian Sphagnum-dominated mires the aim is to minimize fluctuation of the water level, which can be achieved by reconstructing the buffer zone.
