Had an interesting trip out yesterday added another 6 species of fungi to my list. This shot though is a little different, something that probably most don't see. It is the veil or cortina (curtain) that is typical of the genus Cortinarius. It protects the gills when they are young and immature.The Cortina is colored rusty brown due to the spores dropping onto it. ( photo / image / picture from Kildale's Garden ) [/img]
Many mushrooms can be ID'd by the underside, that is why in the books it usually shows this. If there are a number of the species about we always try to take the underside.
I like to look at the underside of mushrooms too. Not only to ID but to figure out how mature it is. Young champignons are white, the more mature ones are black. I think the gills are delicate. All those thin slices neatly placed in a row.
