Walk with me. I know, we’ve done this loop in the State Park at my doorstep many times before. Yet every year I feel compelled to post the photographs of a yellow/orange-dotted world that appears early November, signaling transition, like yellow lights are wont to do.

There is something so utterly optimistic about yellow or orange dots swarming tree trunks, or yellow leaves providing contrast for the increasingly milky brook, or migrating birds – thrushes to be precise – fitting into the color scheme. A last Hurrah before darkness settles in.

There is something tangibly sensuous about the moist surfaces,

and something mysterious about the lamellae and gills.

A recently launched organization called SPUN (Society for the Protection of Underground Networks) is devoted to study and protect fungi to safeguard biodiversity and curb climate change. They have a pretty slick website and ambitious plans to map mycorrhizal fungi, tiny organisms that intertwine with roots of certain tress and nearly all the other plants in specific forests. You can see videos of their field trips in South America and Europe and learn about the scientists involved – they call themselves Myconauts, a clever contraction of the mushroom subject and the associated explorative adventures. For a shorter, quite educational summary essay I went here – much to learn.

No need to return to Chile, though, as much as I’d be tempted – the visual harvest in forests closer to home is just as beautiful.

Independently, since I was reading about fungi, I chanced on new research that shows fungal DNA in various human tumors. We have no clue if there is a causal connection – if fungi, in other words, could be responsible for certain cancers – we just know there is a link.

A small number of fungal cells have been found in 35 different cancer types, with fungal species composition differing among them. What are they doing there? How did they get there? Are they participating in pathology, or are they just taking advantage of immune system suppression in cancerous tissues? Or maybe there are immune cells that ate fungi and carried sequences to a tumor site?

If we knew what their role is we could use them in diagnostic procedures as markers for pathological growth. Or, more excitingly, if we knew how they got into the tumors we could theoretically have cancer-fighting drugs hitchhike on those cells and deliver the chemo specifically on site, a breakthrough in therapeutics.

Enough, let’s not spoil a perfectly glorious fall walk with thoughts of disease or environmental destruction. Let’s enjoy the ruffled beauty,

and the occasional daily wild life in search of a tasty morsel.

And for sound today there is some use of bio data sonification to help a listen to some oyster mushrooms. Changes in electrical resistance are converted into control signals for a eurorack modular synthesizer. The guy who records all kinds of fungi, electronic musician Noah Kalos, a.k.a. MycoLyco, is based in North Carolina. His goal: “just being able to find a signal that we can really observe helps to raise awareness that fungi are all living, we’re all part of the same thing.”

Alternatively, we can just listen to Massenet’s classical capture of thoughts in fall.
