Three species of the genus Psathyrella are described and illustrated in the paper. one of them: P. hydrophiloides is new to Poland, while two others: P. conopilus and P. murcida are new to the Polish Carpathians
New localities of Hygrocybe salicis-herbaceae were observed during the research on the fungi of the alpine zone in the Carpathians. This is the first record of this arctic-alpine fungus in the South-Eastern Carpathians. Macro- and micromorphological characters of the Carpathian collections are compared with the descriptions from other regions. A revision of literature data indicates that the sites in the Parâng Mts reported here are the only known localities of the species from the entire Carpathian range.
Data concerning morphology, ecology and distribution of Polish representatives of the genus Xerula Maire are discussed in the paper. All available specimens of X. pudens and X. melanotricha from Polish herbaria were reexamined to verify their identity and geographical distribution. Several new localities of X. melanotricha in the country are provided. A key to European taxa of the genus is proposed.
Meriderma represents a recently described genus of nivicolous myxomycetes with high morphological variability. Due to many complications in its taxonomy and species recognition in the past, the group was considered a morphologically variable complex. Recent clarifications and recognition of morphological boundaries into species and morphotypes has fostered a classification revision of specimens found in the Carpathians. Material used in this study was systematically collected in the Polish part of the Carpathians from 2004 to 2009. As a result of micro- and macroscopic observations of 54 collections, we recorded nine taxa of Meriderma. Seven of these (all but M. carestiae and M. cribrarioides) are the first records for Poland and for the Carpathians overall. Our observations based on analysis of spore ornamentation by SEM are in accordance with recently proposed classification and confirm segregation of taxa based on spore ornamentation pattern.
All available published data on the occurrence of Russula species in Tatra National Park are summarized. Excluding the doubtful data, which are discussed herein, 66 species are recognized in Tatra National Park. Within each of the three main geomorphological units of the range, 42 species were recorded in the West Tatras, 18 in the High Tatras, and 16 in the Belanske Tatry Mts; additionally, 35 species were found in areas outside the Tatra Mts but within the National Park borders. Montane forests are the richest in Russula species (58); 13 species were found in the subalpine and 8 in the alpine belt. The number of reported species is highest in the Polish part of the West Tatra Mts; almost no data are available from the Slovak High Tatras. The smallest unit, the Belanske Tatry Mts, is the Tatra region best studied for alpine species. In comparison to other regions in Poland and Slovakia, Tatra National Park seems to be relatively well investigated, but in view of the richness of habitats in the Tatra Mts, we believe the actual diversity of Russula species in the region is higher than presently known.
A new to Poland species of a myxomycete, Arcyria marginoundulata, was found at two distant localities in the southern part of the country. Polish specimens are typical and have all important features characteristic of the species: minute, grey, stipitate sporocarps, calyculus concentrically plicate at margin, spiny capillitium and small spores covered with few irregularly distributed larger warts. The species was found growing on alder female catkins. It seems that this substrate is specific for A. marginoundulata in Europe.
The paper gives an annotated list of 40 species of macrofungi found in the Białowieża Forest recently. Two genera (Mycoaciella J. Erikss. & Ryvarden and Sphaerobasidium Oberw.) and nine species (Alnicola amarescens (Quel.) R. Heim & Romagn., Ceriporiopsis rivulosa (Berk. & M. A. Curtis) Gilb. & Ryvarden, Henningsomyces puber (Romell ex W. B. Cooke) D. A. Reid, Mycena silvae-nigrae Maas Geest. & Schwobel, Mycoaciella bispora (Stalpers) J. Erikss. & Ryvarden, Psathyrella maculata (C. S. Parker) A. H. Sm., Sphaerobasidium minutum (J. Erikss.) Oberw. ex Julich, Steccherinum tenuispinum Spirin, Zmitr. & Malysheva, and Xenasma pruinosum (Pat.) Donk) are reported for the fi rst time from Poland. A further 23 species are new for the Białowieża Forest: Antrodia mellita Niemela & Penttila, Antrodiella citrinella Niemela & Ryvarden, Asterodon ferruginosus Pat., Athelia decipiens (Hohn. & Litsch.) J. Erikss., Byssocorticium atrovirens (Fr.) Bondartsev & Singer ex Singer, Conferticium ochraceum (Fr.) Hallenb., Coniophora olivacea (Fr.) P. Karst., Crepidotus crocophyllus (Berk.) Sacc., C. lundellii Pilat, Dacryomyces tortus (Willd.) Fr., Exidia villosa Neuhoff, Hyphodontia pruni (Lasch) Svrček, Kavinia alboviridis (Morgan) Gilb. & Budington, Lentinus suavissimus Fr., Mycoacia uda (Fr.) Donk, Peniophora limitata (Chaillet ex Fr.) Cooke, Pezicula acericola (Peck) Peck ex Sacc. & Berl., Piloderma byssinum (P. Karst.) Julich, Pseudomerulius aureus (Fr.) Julich, Rectipilus fasciculatus (Pers.) Agerer, Sebacina incrustans (Pers.) Tul. & C. Tul., Sistotrema raduloides (P. Karst.) Donk and Trechispora hymenocystis (Berk. & Broome) K. H. Larss. The species new for Poland are described and their micromorphological characters are illustrated.
