Horseradish root
Horseradish is the long white root of Armoracia rusticana, a perennial of the mustard family. Grated, it releases a sharp, nose-clearing heat that vinegar fixes in the sauce.
Mushrooms
A spring pink-spored mushroom associated with Rosaceae. European food use is documented, alongside a Turkish poisoning report and unresolved species-complex records in Mexico.

Index Fungorum accepts Entoloma clypeatum (L.) P. Kumm. (1871), based on Agaricus clypeatus L. (1753). It belongs to Entolomataceae. Descriptions report a grey-brown, often umbonate cap, pale gills that become pink, and a pinkish spore deposit. The species is associated with Rosaceae shrubs and trees, including plum and hawthorn. These features describe the taxon; they are not sufficient to identify a wild mushroom, and similar pink-spored Entoloma can be hazardous.
European accounts place fruiting in spring to early summer, often around April–June; a Czech mycology account gives March–June. The calendar varies with region and weather. UNAM records a complex of related species near E. clypeatum across parts of Europe, Asia and North America, and reports Mexican records in Chihuahua, Jalisco, Puebla, Tlaxcala and the State of Mexico. The Mexican account explicitly says this complex is not taxonomically resolved there, so those state records should not be read as confirmed occurrences of E. clypeatum sensu stricto. Market reports from Ozumba and Tlaxcala likewise concern local names and the complex rather than certain species identifications.
Use records are regional rather than universal. A Croatian food-chemistry study included E. clypeatum among ten popular Croatian wild edible mushrooms. An ethnobotanical survey of Ukrainians in the western Maramureș region of Romania discusses the species in the local wild-food repertoire and notes it among mushrooms eaten by Ukrainians; it does not provide a species-specific preparation method. These reports document cultural and research contexts, not a validated way to determine whether a specimen is safe.
A peer-reviewed report describes four people poisoned after eating wild mushrooms collected in Burdur Province, Turkey. The authors identified the specimens as E. clypeatum from morphology and spores. The report is a meaningful safety signal, although the identification method and later recognition of species complexes limit what it proves about all populations currently given this name. It should be presented alongside, not erased by, European edible-use accounts. No visual description, market name or geographic range is a reliable basis for personal identification.
A Croatian food-chemistry study included this species among ten popular wild edible mushrooms; no finer collection locality is given here.
The ethnobotanical study discusses this mushroom in a local wild-food repertoire and reports it eaten by Ukrainians; it does not establish an exact collection site or species-specific preparation.
The paper reports four poisonings from mushrooms collected in this province and identifies specimens as E. clypeatum by morphology and spores. This is a safety-event association, not a range or culinary-use claim.
