Abstract

We determined the elemental profile of 16 edible mushroom species from the Făget Forest, near Cluj-Napoca, and of 12 species from the Apuseni Mountains. One-way ANOVA showed no difference in the elemental content of mushrooms when the two regions were compared. Some species accumulated high amounts of trace elements, i.e. Boletus edulis (Ag, S, Zn), Macrolepiota procera (Cu), Lactarius volemus (Co), Russula emetica (Mn), Armillariella mellea, and Chantarellus cibarius (Cr). The cadmium content was the highest in the case of Leccinum scabrum and Boletus edulis. These two species presented elevated risk levels for all age-groups when they are consumed regularly.

Abstract

Diadesmis fukushimae, a rare oligotraphenic diatom, was found in some high mountain lakes of Romania. Its occurrence in the Parâng and Retezat Mountains is the second European record of the species. To date D. fukushimae has been known only from the type locality (Shenandoah National Park, Virginia, USA) and from a spring (Grotta Guernica, Dolomiti Bellunesi National Park (south-eastern Alps, Italy). Investigation by scanning electron microscopy showed that this species should be transferred to the recently established genus Humidophila. A new combination is proposed, Humidophila fukushimae. The morphological details of the European population are also presented.
