FOTD #065 : parrot waxcap! (gliophorus psittacinus)

the parrot waxcap / parrot toadstool is a mycorrhizal fungus in the family hygrophoraceae. it is widely distributed in the grasslands of western europe, the UK, iceland, greenland, the americas, south africa & japan.

the big question: can i bite it?? it is edible & has a mild taste !!

g. psittacinus description :

"the parrot toadstool is a small mushroom, with a convex to umbonate cap up to 4 centimetres (1.6 in) in diameter, which is green when young & later yellowish or even pinkish tinged. the stipe, measuring 2–8 cm (0.8–3.1 in) in length and 3–5 mm in width, is green to greenish yellow. the broad adnate gills are greenish with yellow edges and spore print white. the green colouring persists at the stem apex even in old specimens."

These pictures show PAS (purple/pink) and GMS (brown/blue) staining of a lymph node biopsy from a canine patient with lymphadenopathy and weight loss. Histology was suggestive of likely a fungal organism (bright pink in the PAS stain and dark brown/black in the GMS stain), however a mixed infection with an algal species could not be definitively ruled out without microbiology.

Our microbiologist cultured an Aspergillus species from this dog, and is in the process of ruling out any other possibilities.

What's especially cool is in one of the PAS pictures, you can see an organism trapped within an actively dividing macrophage!

hi- quick question since I know you're someone who's written several papers- Do you know if you/other people who have written scientific papers are okay with emails about questions about those papers?

I'm someone who studies hyenas- amateurishly -and papers about extinct species of hyenas are really interesting to me but I can't exactly digest them very well because I don't understand the words being used. Like, what in heavens names is a 'metaconid' what does this mean!!!!!

In general authors are happy to receive such questions, but might not have enough time to give you the answer you are looking for. Still, always worth reaching out.

A metaconid is a part of a molar. But I understand this is just an example among of the general issue you are trying to illustrate. What I have learned from years of reading unfamiliar jargon, and listening to podcasts like The Tetrapod Zoology Podcast that use jargon with reckless abandon, is that in general either (a) the words that are encoded in jargon aren't *that* important to understand the grand themes of what is being discussed, or (b) their meaning can be deduced based on context cues. When I come across one that is key but really cannot be deduced, I will google it, and often Wiktionary or similar will have an answer.

The more you read, the more familiar you will get with the jargon, and the less you will need to google or ask. So, I encourage you to read broadly, and chase those interests!

I’ve done it! I’ve designed such an incredibly cursed molecule that MolView doesn’t even assign it a systematic IUPAC name. Behold:

The image doesn’t even show up right in the post editor lol. This thing would have such unbelievably ridiculous angle strain that if a molecule of it was ever assembled, it would almost certainly degrade instantly. Possibly violently.

I sometimes think about bacteria growing on (in?) an agar plate and how strange it must be from their perspective. To be taken from your (many times hostile) natural habitat and placed in (on?) an alien landscape made entirely of food that caters perfectly to your dietary needs. You live there, and your descendants thrive there for generations after, and then comes a Cataclysm. And they die in an inferno of steam and pressure, suddenly and unexpectedly.

And you never knew you were the fortunate ones. Your brethren lived their lives in other equally alien worlds, except theirs were tailored to kill them, torture them, or starve them of necessary nutrients. Their torment and your bliss serve a purpose ufathomable to you, a purpose of creatures so vast and unknowable, they might as well be Gods.

I think about bacteria sometimes.
