Keep having this issue – grow beautiful, massive harvests of sunchokes / Jerusalem Artichokes, only to find they’re all mushy, decomposing messes in a sea of this white, feathery mold. It almost looks like a slime mold with all the little tiny nodules that accompany it, or some other kind of organism. It has only affected sunchoke roots thus far, and only those in specific areas. For reference, I live in Hawai’i, and I’m not sure that it’s something common locally as experienced gardeners I’ve asked who live here have never seen anything like it.
Edit: It seems to exclusively affect the tubers / roots as well, with no visible above ground growth that I’ve seen thus far.

Just a guess here.. maybe *Sclerotinia sclerotiorum*, which is a soilborne disease which can occur if sunchokes are grown in the same place multiple times.

Send your photos to the local Cooperative Extension office to get an accurate description. Just about every county in the US has a Cooperative Extension office. They’re funded by the Department of Agriculture and your state’s public university and they don’t sell anything. Because they’re not out to make a profit, most of their services are free or very low cost. Part of their job to identify and keep track of plant diseases and insects for farmers and gardeners. They typically give you both organic or non-organic advice, but it’s all local advice for your area. It’s up to you what to choose. They’re typically an under-utilized resource. Here’s the website for the first one I found in Hawaii. Contact them about sending in your photos for identification. https://cms.ctahr.hawaii.edu/ce

I had this on my star Jasmine!! It made the soil really strange and sandy so I repotted it. It’s doing well now and I use an antifungal to keep it from coming back
