Velvet swimming crab. One of the largest of the swimming crabs. A small spider crab with sweet, flaky white flesh. It has good flavour but is too small to pick, so is used in soups.
Russula. Around 750 worldwide species of mushrooms compose the genus Russula and by no means are all of them edible. They are typically common, fairly large, and brightly coloured - making them one of the most recognizable genera among mycologists and mushroom collectors. Their distinguishing characteristics include a white to dark yellow spore print, brittle free white gills, and an absence of partial veil or volva tissue on the stem. Members of the related Lactarius genus have similar characteristics but emit a milky latex when their gills are broken.
Greencracked brittlegill. A variety of wild mushroom which, as its name implies, is a sort of olive green with darker green markings and with creamy brittle gills. 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.
