Ingoldian and Aero-aquatic Hyphomycetes
Aquatic hyphomycetes are an extremely interesting and generally under-recorded group of fungi. They often produce complex and uniquely shaped condia. Although there exists marine hyphomycetes, the most accessible ones to the amateur are in fresh water.
Ingoldian fungi are aquatic saprobes, breaking down plant matter and produce their conidia under water. Aero-aquatic fungi are saprobes similar to ingoldian fungi, but only produce condidia once they are in contact with the air. However in this post we will be looking at both because they can be found in the same environments and samples.
Scum formed from running water is often a good place to look for these fungi as they catch the spores. Usually the season for these kinds of fungi is considered to be during the winter, however, I am convinced this is only the case because no one cares too look at them when there are other things around!
Recently I had the chance to collect some scum formed at the bottom of a waterfall in here in Scotland, and managed to find atleast 12 species in these samples! Here I will list the resources I have used to identify these species to make it easier for you!

Super cool, I will see if I can find some. Are these stained?
Yes these are stained with cotton blue. You can see them without it, but it certaintly helps as most are not pigmented! Good luck in your search! Let me know if you find anything :)
