Powdery brittlegill. A variety of wild mushroom, ranging in colour from blue to light green or grey. Most brittlegills resemble other ones that are inedible and some will cause gastric problems. You can normally detect what type it is by the flavour. A tiny tasting will immediately reveal whether or not it is edible, but it is worth spitting it out immediately if you detect a bitter taste.
Niva is a wheel of crumbly blue cheese made with cow's milk exclusively from milk from the designated area in South Bohemia. It has an ivory to cream-coloured paste with regular green to bluish-green veins. A cream to light brown rind may show some signs of the blue veining and have a partly waxy finish. This cheese contains 50% fat (dry). It may be found in the following dimensions: 18-20 cm (7-8") diameter by 10 cm (4") deep, weighing around 2.8 kg (6 lbs). Affinage is at least four weeks and then wrapped in aluminium foil. The flavour is salty and pungent.
