I found an ancient text which states that truffles do not "grow (derive their growth?) from the ground". I have found two medieval opinions on what that means:
- They "don't have roots in the ground, and their growth is from the air."
- Their roots don't have (twigs? shoots? tendrils? thin branches?) which (lit. "do the action of (previous word)/ become (previous word)". Branch out?) under the ground, and (from them? With them?) (fertilize? Become fertilized? Pollinate? Become pollinated? Be fruitful?).
Are those descriptions accurate in light of modern understanding? Is there any sense in which "their growth is from the air" true? How exactly do they grow, and where does their sustenance come from? I have looked at a number of articles, but have had trouble understanding them.
P.S: Please forgive the many possible translations. The true translation may only be a similar word to the ones provided, but not actually any of them. Going through ancient texts can be difficult sometimes. I would also prefer to leave the text unnamed.
