I would give the Letharia dye another try
Would love to… When I was in Oregon this lichen was super abundant. At the moment I am living in Amsterdam (Netherlands), and I see mostly Xanthoria, Evernia, Rhizocarpon, and a few other lichen species that grow on city trees, but they are very small and spotty, nothing compared to the wolf lichen in Oregon. I do miss the Oregon forests with the old growth sequoia redwood trees and all that lichen.

9ft of snow?! I only experienced such deep snow in an urban setting while living in Connecticut for a year. I spent a few years in Oregon but the snow in the area never got so deep while I was there. When I was in the US I was not yet able to identify many fungi as I was mainly obsessed with animals (especially salamanders) back then, so unfortunately I did not really appreciate the diversity of fungi there. Although once in Oregon I did attempt to dye some socks using a wolf lichen (Letharia vulpina) and a pressure cooker. That did not end well.

I see. So it is not necessarily that their mycelium are better at surviving the freezing temperatures, but rather that either they fruit quicker once conditions are acceptable or that their fruiting bodies are more cold tolerant. Thanks, it’s interesting.

Cool! I just read their wiki page and it says
A snowbank fungus, it is most common at higher elevations after snowmelt in the spring.
Snowbank fungus is a new term for me. Not sure yet what makes a fungus thrive through snow. Maybe they have anti-freeze proteins?
Does your area get a lot of snow?

I used 99%. 70% will probably work too. I can test later and let you know.

- Comment on BlackRock is Suing UnitedHealth for Giving “Too Much Care” to Patients After the CEO was Murdered 2 months ago:
As far as I can tell, this is the legal document associated with the lawsuit: …courtlistener.com/…/gov.uscourts.nysd.642027.1.0…
The most significant component of this claim is not the lawsuit itself (examples of frivolous lawsuits are common), but that BlackRock is the one suing. BlackRock doing this is the important and remarkable claim here.
I see no obvious connection between Roberto Faller and BlackRock. To me this looks like a frivolous lawsuit issued by a random inconsequential individual. So, then, framing it as BlackRock suing is blatant misinformation.
I could be missing something here, perhaps there is indeed a BlackRock connection that I was unable to identify. But that Medium article is certainly not explaining the connection. The CBS article does not mention BlackRock.
If there is no connection to BlackRock, then adding “BlackRock” to the title is not click-bait! It is a blatant lie.

- Comment on I probably interact with people who are at the pinnacle of their chosen skill but I'd never know because that skill isn't something that generates fame. 2 months ago:
I think that for mid-levels of fame you can find a mixture of musical skill and self-marketing/entrepreneurship.
But as you go up the ladder of fame you get to the rungs where money is used to pay for an artist’s exposure. The artist becomes an investor’s asset and the “skill” of building fame arguably belongs to the investors / management team. And it is not so much skill as much as it is the power of capital to purchase attention.

Awesome, thanks! I will look into it.

You are welcome! Wanted to do this for some time and writing about it is a way to force myself to think about what I see more carefully.
- Comment on The Inside of Sensirion's SCD4x 2 months ago:
That is very cool! I did not know they were producing in Switzerland. I would like to visit. Do you know if they routinely open to the public?
I wonder if the “magic sauce” is a polyimide. Those polymers are often used as the dielectric layer to make capacitors that are humidity-sensitive. These polymers have sites into which water molecules can reversibly dock such that the occupancy at equilibrium is proportional to the % relative humidity.
- Comment on The Inside of Sensirion's SCD4x 2 months ago:
That is true. To me, the sensor data in itself is of value because I am interested in learning about, for example, whether the CO2 emission changes while the fruiting happens. But it is definitely not necessary for achieving good results. I see it more like a hobby on top of a hobby. Hobby stacking!
- Comment on The Inside of Sensirion's SCD4x 2 months ago:
The CO2 has not proven too valuable because the humidity controller refreshes the air before CO2 builds up. But the humidity sensor is quite handy. I made a simple humidifier and it gets triggered by a raspberry pi over Zigbee when the humidity drops below 85%.
- Comment on The Inside of Sensirion's SCD4x 2 months ago:
Probably not! That was a mistake on my part. The better term would be photoacoustic sensing I believe, so I have edited the post to use that term instead.
Although the response is proportional to the absorbance value at a narrow wavelength range, and CO2 is detected selectively because its molar absorption coefficient is high at that specific wavelength. I think the argument can be made that this is an action spectroscopy method limited to a single point. But I am not quite sure, so ‘photoacoustic sensing’ wins. Thanks!

No problem! Happy to share

I’m happy to share and glad someone else finds it interesting too :D
I also use SHT41 for other projects. It is a very nice sensor. I made an incubator with PID control and tested multiple different sensors, and the SHT41 was my final choice. Responds very fast and its accuracy is excellent.
In my mushroom chamber I have found out that CO2 is not actually an important control variable because the humidity is what changes the fastest and blowing humid air through the chamber brings the CO2 down anyway. So I would probably be able to get away with the SHT41, but measuring CO2 is just fun.

Looking through the archived history of the talk page, I can confirm that the claim on the wiki page is derived from the viral post, and not the other way around: en.wikipedia.org/wiki/…/Archive_3#Chalchiuhtlicue…
