Description
Russula claroflava, also known as Yellow Swamp Brittlegill, is a brightly coloured agaric that has a convex to flat, vivid yellow cap. It grows with birch in very damp or boggy woodland.

Cap convex when young, becoming broadly convex or nearly flat with age. It's tacky to sticky when fresh, but dries quickly. The cap is bright yellow, which diminishes with age, and the margin becomes slightly lined. The skin can easily be peeled off halfway to the centre. The flesh is white and staining and aging slowly grey. Gills at first white, then creamy yellow but discolouring grey with age. Older ones can have grey or black edges, more or less free or reaching but not connected to the stem and fairly crowded. Stem is white, turns grey with age, more or less equal, fairly stout, and smooth. It has no ring. Spore print pale ochre-yellow.

Microscopic Features: Spores are ellipsoidal, measuring 8-9.5 x 6.5-8μm (excluding spines). They are ornamented with mainly-isolated blunt warts, reaching up to 0.6μm in height and connected by only a few lines.

Many mushrooms are poisonous and some are lethally poisonous. It can be very difficult to distinguish between an edible and a poisonous mushroom. Because of that, we strongly advise against consuming wild mushrooms, and this site does not contain any information about the edibility or toxicity of mushrooms.
