About truffles...Truffles are Fungi, from the Tuberaceae family (and they are heavenly!!!), Genus - Tuber.
Truffles are so unique and special that they have their own separate branch of Botany, called Hydnology.
Truffles grow underground, by tree-roots in symbiosis with certain tree species (Oak, Elm, Beech, Hazel and some others). This is called Mycorrhiza.
Through this rare and special union; the Sporocarp (AKA Truffle) is formed.
Their external wall is called the Peridium, which can be smooth or textured, with a colour that varies from light to dark.
The inner part is called the Gleba and it can appear black, white, to reddish brown.
Marbling the Gleba there is a veining separating the cavities, in which are cells, called Aschii, which contain the treasured truffle spores, that ensure future generations will also be savouring them.
The origin of the word truffle appears to be the Latin term tūber, meaning "swelling" or "lump", which became tufer- and gave rise to the various European terms: Danish trøffel, Dutch truffel, English truffle, French truffe, German Trüffel, Greek τρούφα trúfa, Italian tartufo, Polish trufla, Romanian trufă, Spanish trufa, and Swedish tryffel.
In exchange for carbohydrates, truffle fungi provide their host plants with valuable micro and macronutrients, via the roots. Plant macronutrients include potassium, phosphorus, nitrogen, and sulfur whereas micronutrients include iron, copper, zinc, and chloride.
Truffle Hunters prefer the use of Dogs to identify truffles under the soil. Historically, Pigs were used. However, they had a tendency to eat the truffles once found!!!
