Petersen was described as a new species based on material from eastern Russia and USA: Alaska (Redhead and Petersen 1999). Fruitbodies of this species were also collected in these two regions (Hughes et al. 1999), which suggested the idea of its migration between Eurasia and North America via the Bering land bridge during the last glacial maximum (Redhead and Petersen 1999, Hughes et al. 1999). However, more recently, the fungus has been detected in western Russia, Japan, USA: New York State, northern Thailand (Petersen and Hughes 2007), Canada: British Columbia (Petersen et al. on-line) and Tibet (Anonymus on-line).  \nDuring our study of taxonomy and biogeography of the genus Flammulina in Central Europe in the years 2004–2007, we identified three specimens at the München herbarium (M) as F. rossica. Two of these collections were collected in  \nCZECH MYCOL. 60(1): 113–121, 2008  \nGermany, one in USA: South Dakota. Thus, these collections also support the fact that F. rossica is widespread (but rare) in the Northern Hemisphere and not only trans-Beringian (Petersen and Hughes 2007).  \nThe aim of our paper is to present the three mentioned collections ofF. rossica from herbarium M, and to summarize current knowledge of its distribution, ecology, morphology and biology.  \nMATERIAL AND METHODS  \nMore than 40 Flammulina specimens deposited in herbarium M were studied in 2004. Among them 3 specimens of F. rossica were identified. The micromorphological characters were observed in dried material under an Olympus CX41 light microscope in oil immersion. Fragments of lamellae, stipe and pileipellis were examined in 5 % KOH, Melzer’s reagent and a solution of Congo Red in ammonia (1 ml of 25 % ammonia dissolved in a filtrated solution of 1.5 g Congo Red and 50 ml distilled water). Extreme values of microcharacters were estimated as 10 and 90 percentiles of 30 measurements, the values in parentheses are the 5 and 95 percentiles. Q is the ratio of spore length and width. The abbreviations of herbaria are cited in accordance with the Index Herbariorum (Holmgren et al. 1990). Literature data on specimens are presented in their original form.  \nRESULTS AND DISCUSSION  \nFlammulina rossica Redhead et R. H.
