The recipe Phil Gates retrieved to produce ink from inkcap mushrooms (Country diary, 16 August) is a great example of the value of fungi. And it’s not just ink: research is under way to produce textiles, paper, insulation and other materials from mushroom species. Perhaps a mycological version of the Guardian isn’t far off.

Chris Mullen is critical of those standing for parliament at a young age (Age apparently gives you wisdom, so why doesn’t Joe Biden know when to quit?, 22 August). Clearly, he was not of that view when he stood as a candidate in Devon North in 1970, when he was 22.
