An inventory studies on Microlepidoptera were performed in 2008 on meadows neighbouring the then planned War-saw-Modlin Airport. The studies revealed the occurrence of 165 species representing 26 families in the area including 37 species first noted in Masovian Province. Species that deserve special attention due to a low number of sites in Poland include: Depressaria pimpinellae (Zeller, 1839), Scythris seliniella (Zeller, 1839), Schiffermuelleria schaefferella (Linnaeus, 1758), Pseudatemelia flavifrontella (Denis et Schiffermüller, 1775), Nothris verbascella (Denis et Schiffermüller, 1775), Ptocheuusa inopella (Zeller, 1839), Epinotia rubiginosana (Herrich-Schäffer, 1851), Lobesia artemisiana (Zeller, 1847), Phtheochroa pulvillana (Herrich-Schäffer, 1851), Anania verbascalis (Denis et Schiffermüller, 1775), Epascestria pustulalis (Hübner, 1823).
Sitticus terebratus is a spider species known from a few localities in Poland. The records refer to the south Poland - in the West Beskid and the Orawa-Nowy Targ Basin, as well as in the north-eastern part of the country. The study revealed 13 new localities of this species ranging from the Babia Góra Mts to Bieszczady Mts. All sites of S. terebratus are synanthropic but observations indicate that the species is very rare and it may be endangered both in Poland and in Europe.
Chamaecytisus albus (Hacq.) Rothm. is an extremely rare species, which is inserted in many European red lists and red books. Its continuous range covers the south-eastern part of Europe. That species grows in intensely insolated and calcareous habitats of xerothermic grasslands. Only one station of White Broom had been known in the valley of the Bug river, near Hrubieszów, but in 2007 a new one was discovered near Jędrzejów. That station is located the farthest in the north and the west in Europe and it is completely detached from the continuous range.

Valsa viburni, a rare fungus in Europe?

86%
The paper provides brief illustrated description and general distribution of Valsa viburni. The fungus is found to be highly host-specific and confined to Viburnum lantana. According to currently available data on its distribution, the species has small number of records, fragmented range and is shown to be rare in Europe. However, before assessment of the species, information on any additional unrecorded specimens is needed. On the example of V. viburni, some issues on fungal conservation for species of microfungi are considered.

First Polish records of Myxomycetes rare in Europe

86%
Seven species of Myxomycetes are reported from Poland for the first time. These are Arcyria virescens, Cribraria costata, C. elegans, C. languescens, C. mirabilis, C. pertenuis and Trichia flavicoma. They have very few localities in Europe and Cribraria pertenuis is known only from two sites worldwide. The species are described and illustrated with microphotographs, including first published micrographs of C. pertenuis. Localities are given and the taxonomy and ecology of each species are discussed.
Improphantes geniculatus (Kulczyński 1898) is a rare steppe spider species, known from a few locations in Central Europe and from Southern part of Russia. Authors give information about afirst location of I. geniculatus in Poland, affirmed which is in “Góry Pieprzowe” Reserve near Sandomierz.
The paper presents the actual vascular flora of the “Dębowiec” nature reserve identifi ed in 2004-2009 and supplemented on the basis of literature data. The vascular flora consists of 306 vascular species, including the following mountain species: Abies alba, Acer pseudoplatanus, Anthriscus nitida, Chaerophyllum hirsutum, Huperzia selago, Polygonatum vericillatum, Ribes alpinum, Sambucus racemosa and Valeriana sambucifolia. It must be stressed that there are 29 rare species in the regional scale of Central Poland.
Rare epixylic moss Buxbaumia viridis, which is one of the “Annex II” species of the European “Habitat directive”, has been recorded at 124 localities in the Czech Republic in course of the last 13 years. Most of them were discovered in the last five years following a dedicated search at both historical sites of occurrence and new localities with putatively suitable habitat conditions. The recent and historical area of occupancy and extent of occurrence are not obviously different, although most of the recent localities are concentrated in the Western Carpathians and the Hrubý Jeseník Mts. Surprisingly, only 38% of the localities are located in natural forest habitats, of which herb-rich and acidophilous beech forests were among the most commonly inhabited ones. The rest of occurrences were recorded in non-natural forests (habitats strongly influenced or created by man), particularly the coniferous forest plantations. Sufficient amount of decaying wood of the advanced decay stages, as well as sufficient and constant humidity are crucial prerequisites for the occurrence of B. viridis in both types of forests. True epixylic moss Herzogiella seligeri and the liverwort Chiloscyphus profundus were recorded as the most common associated species, while the rest of commonly co-occurring species were facultatively epixylic, ground or ubiquitous bryophytes; other specialized and rare epixylic mosses or liverworts were only rarely recorded. We also designed a potential distribution model for B. viridis based on the distribution of habitats most commonly occupied by the studied moss. Despite the simplicity of the model, its close match with the recent distribution in the Western Carpathians, the Hrubý Jeseník Mts. and Šumava Mts. supports its relevance for the real distribution of B. viridis.
