The 2013 issue by Spanish Correosdedicated to Mycology consists of three types of wild mushrooms with very different morphological and culinary characteristics: AGARICUS XANTHODERMUS, MARASMIUS OREADES AND AMANITA PANTHERINA.
AGARICUS XANTHODERMUS: The cap has a diameter of 6-12 cm. At the top, it is frustoconical and gradually opens until it is almost flat. It is white and sometimes has grey tints. When rubbed it turns yellow. The gills progress from pale-pink to brown.
The stipe measures 5-12 cm. It is white and has a membranous ring. It grows in the autumn in fields, forming circles and rows.
It is a poisonous mushroom that can be confused with edible mushrooms, from which it can be distinguished by the yellow colour it acquires on rubbing it and its unpleasant odour. Ingestion can cause gastric problems.
MARASMIUS OREADES: It is a mushroom commonly known as the Scotch bonnet or fairy ring mushroom. The cap has a diameter of 2-6 cm. At the top it is semi-spherical and then flat. It is pale tan with a "nipple" in the center. The gills are thick and distant.
The stipe is the same colour, thin and rubbery, difficult to break and can measure up to 10 cm. It grows in autumn and spring forming rings or rows with many samples. It is edible and good quality. It could be confused with a similar mushroom: marasminscollinus, which is poisonous and from which it can be distinguished as the latter has a brittle stipe and tighter gills.
AMANITA PANTHERINA: Also known as AMANITA PANTERA. It is a slim and long mushroom but poisonous.The top of the cap is convex and gradually flattens out. It has a diameter of 10-12 cm. It is pale tan to brown and covered in the remnants of the VOLVA tissue that covered it before it grew, in the form of white snowflakes.
The gills are tight and white. The stipe is slim and white and can also measure up to 15 cm with a ring inside. At the base, the stipe is wrapped in a collar-like roll of volva tissue.
It is born in summer and autumn in oak and beech woods, although it can also appear in conifer woods.
Ingestion causes severe poisoning. It could be confused with other amanitas, such as the MUSCARIA, RUBESCENS or SPISSA.
