My first drying process was a success :) I tooked it slow and clumsy but it ended well, time will tell how well by its concervation qualitty, but I think it will be ok :)

In Portugal the Parasol Mushroom is very common, its nicknames are "Touxeiros", or "Frades" or "Gasalho" (it is a small country, but lots of isolated provinces, so lots os different nicknames in each one). It grows a lot next to cultivated soils at the beginning of Autumn, when time is not very cold like in the late November. It can be confused with some toxic ones, you are right. In portugal the most dangerous look alike and toxic one is the Macrolepiota Venenata. The key tips to identify the Procera (=Parasol) are: vertically movable ring at the top of the stem; stem higher than the cap width; brown salient nipple at the cap center; no color changing when bruised; stem colour like a brown zebra pattern; volva without external skin (these characteristics are the main ones to identify the Procera and differentiate from the poisonous Venenata; the cap should also be 20 to 40cm diameter and stem higher than 10cm (this is important to distinguish from another deadly look alike one I don't remember the name, since it is always a lot smaller than the Procera, never bigger than that). There is another look alike (Chlorophyllum molybdites) but it don't grows in here (and has faintly green gills, not fully white ones). In this article, if you find one Prasol one day, starting at page 12, there are pictures of the main differences between the Procera and the Venata (it is in portuguese, but the pictures are nice and self-explanatory): http://www.drapc.min-agricultura.pt/base/documentos/mproceravenenatafina...

Mushrooms are like women: desirable and beautiful, but dangerous, some can stop your heart if we don't take care xD
