Auriculariopsis albomellea (Agaricales, Schizophyllaceae) new for Poland WŁADYSŁAW WOJEWODA Bobrzeckiej 3/23, PL 31 216 Kraków W o j e w o d a W.: Auriculariopsis albomellea (Agaricales, Schizophyllaceae) new for Poland. Acta Mycol. 41(1): 49 54, 2006. The article deals with the taxonomy, ecology, general distribution and threatened status of Auriculariopsis albomellea Bondartsev Kotl. (Basidiomycetes). In Europe it is known only from Czech Republic, France, Sweden and Ukraine, in Africa from Canary Islands, in North America from Canada and United States. In Poland the fungus was found for the first time in NE part of the country, in a pine forest, on dead twigs of Pinus sylvestris. Habitat and distribution of this saprobic fungus in Africa, Europe and North America are described, list of synonyms and important references are cited, Polish name is proposed. Key words: fungi, Basidiomycetes, distribution, habitat, taxonomy, threat INTRODUCTION In Poland hitherto was known only one species from Auriculariopsis genus: A. ampla (Lév.) Maire. It occurs especially on Populus, also on Salix, and is rather com- mon in Poland (Wo j e w o d a 2003). In the fungarium of the Institute of Botany of the Polish Academy of Sciences, was found second species from this genus: rare fungus – A. albomellea (Bondartsev) Kotl., new for Poland.

For cultural descriptions see N a k a s o n e (1990). HABITAT AND GENERAL DISTRIBUTION Aurculariopsis albomellea occurs in forests and at skirts of peatbogs. Basidiomata of this saprobic fungus occur on dead fallen trunks, and on attached or fallen corticate branches of coniferous and deciduous trees: Abies, Alnus, Corylus, Pinus and Quercus, April–December. According to G i n n s and L e f e b v r e (1993) the fungus may be associated with a brown rot, according to N a k a s o n e (1996) it is associated with a white rot. For the first time it was found in Sweden in 1905 (S t a l p e r s 1988). It is known hitherto from Northern Circumpolar: Africa, Europe and North America. Af- rica: Spain, Canary Islands: Tenerife, in association with Arbutus canariensis, Picconia excelsa, and Visnea mocanera, on dead wood, not identified (R o d r í g u e z - A r m a s et al. 1992). Europe: Czech Republic, Bohemia, 5 localities: in forest with Pinus and at a skirt of a peat-bog with Ledum palustre, Sphagnum sp., Vaccinium myrtillus and V. uligi- nosum, on dead trunks and attached branches of Pinus uncinata, on bark and wood of Pinus sylvestris, and on dead, not fallen branches of Quercus sp. (P o u z a r 1954, P i l á t 1969, N a k a s o n e 1996). France: on Corylus avellana (B o i d i n , G i l l e s 1990); Slova- kia: on branch of Pinus nigra (P o u z a r 1954); Sweden: 2 localities, on Pinus sylvestris, and on dead, dry branches of Quercus robur (E r i k s s o n , R y v a r d e n 1975; S t a l p - e r s 1988; N a k a s o n e 1996); Ukraine: in forest, on dead branches of Pinus sylvestris (B o n d a r t s e v 1927; K o t l a b a 1988; N a k a s o n e 1996; A k u l o v et al. 2003). North America: Canada, Yukon Territory, on bark of fallen Alnus crispa; United States: Ari- zona, Maine, Mississippi, New Mexico, Wisconsin, on fallen or attached dead corticate branches of Abies concolor, Pinus palustris, P. ponderosa, P. resinosa and P. strobus (N a - k a s o n e 1996). According to N a k a s o n e (1996, after H a l l e n b e r g 1981), Auriculariopsis ampla is known also from Iran in Asia, but by H a l l e n b e r g (l.c.) this species is not men- tioned.

Auriculariopsis albomella (Agaricales, Schizophyllaceae) nowy gatunek dla Polski S t r e s z c z e n i e W fungarium Instytutu Botaniki im. W. Szafera PAN w Krakowie stwierdzono okazy Auriculariopsis albomellea, gatunku ostatnio zaliczanego do rodziny Schizophyllaceae w rzę dzie Agaricales (Basidiomycetes). Okazy tego grzyba zebrano w 1976 r., w północno wschod niej Polsce, w Puszczy Myszynieckiej (północna część Puszczy Kurpiowskiej), w rezerwacie Mingos, w subkontynentalnym borze świeżym Peucedano Pinetum, na martwych, opadłych, pokrytych korą gałązkach Pinus sylvestris. Jest to gatunek nowy dla mikobioty Polski. Publiko wany był z Europy (Republika Czeska, Francja, Słowacja, Szwecja, Ukraina), z Afryki (hisz pańskie Wyspy Kanaryjskie) i z Ameryki Północnej (Kanada, Stany Zjednoczone). Rozpostar te, dyskowate, brązowawe, białoobrzeżone owocniki tego saprobowego grzyba z gładkim lub gruzełkowatym hymenoforem, występują na martwym drewnie drzew iglastych i liściastych: Abies concolor, Corylus avellana, Pinus nigra, P. palustris, P. ponderosa, P. resinosa, P. sylvestris, P. strobus, P. uncinata, Quercus robur i Q. sp. Uszaczek białobrzegi, jest gatunkiem rzadkim. W Szwecji umieszczono go na czerwonej liście grzybów zagrożonych w tym kraju, z kategorią „lokalnie wymarły”. W Polsce gdzie stwierdzono go tylko raz, w rezerwacie leśnym, też przy puszczalnie jest zagrożony. 2014-01-01T11:43:26+0100 Polish Botanical Society
