Description:Junghuhnia fimbriatella (Peck) Ryvarden
Originally described from North America, Junghuhnia fimbriatella also occurs in East Asia:
Kamchatka (Parmasto 1963a, Bondartseva 1998), NE China (Dai 2000), and in several Centra] Euro-pean countries (Ryvarden & Gilbertson 1993), but is not reported from North Europe (Hansen & Knudsen 1997). Now OMI collected it from the Veps Forest, on fallen, fairly strongly rotten aspen trees, 60-70 cm in diameter. New to European Russia.
This polypore is a look-alike of J. lacera/separabilima (next species), but differs mainly by its spore dimensions. They are (2.1-)2.3-2.8(-3.2) x (1.7-)1.9-2.2(-2.4) µm, L=2.52 µm, W=2.06 µm, Q=1.22 (n=1 80/6). Critical is the thickness of the spores: in J. fimbriatella the diameter is about 2 µm, in J. lacera/separabilima about 3 µm.
