I have my Bio 302L students at Northern Kentucky University to thank for this fun find. This amazing bacteria colony grew out of a water sample taken from the Lakeside Commons pond, directly behind the Campbell County Cooperative Extension offices. On 1/17, water and a little sediment was collected from the edge of the pond. On 1/19/2023 my microbiology students diluted a sample and spread plated it onto glycerol yeast-extract media, which is selective for gram-positives such as actinomycetes. This colony grew quietly on a 0.01 mL plate that had been forgotten in the fridge. Actinomycetes often have strange colony morphologies, so that's my guess on an ID for this. Neither I nor my colleagues have seen a colony like this before.
