FOTD #126 : entoloma haastii!

entoloma haastii (no common name) is a mushroom in the family entolomataceae :-) it is only known to grow in aotearoa, where it often sprouts in leaf litter from southern beech plants.

the big question : can i bite it?? the edibility is unknown, but it is said to be sharp-tasting & sour / bitter.

e. haastii description :

"the cap is initially conical later developing an umbo & becoming rounded or bell-shaped, reaching diameter of 1.5–5.5 cm (0.6–2.2 in) in diameter. older fruit bodies have margins that are turned upward. the cap colour is dark brown or soot-brown but always has a bluish tinge. the surface is dry, covered by radially arranged wrinkles or veins, neither striate nor hygrophanous. the gills are adnexed to almost free from attachment to the stem. they are somewhat distantly spaced, with between 16 & 22 gills extending fully from the stem to the edge of the cap, in addition to one to three tiers of interspersed lamelluae (short gills that do not extend fully from the stem to the cap edge). the gill colour is grey-bluish later becoming pink, & the gill edges are straight or somewhat saw-toothed, & the same colour as the gill face. the stem is 4–10 cm (1.6–3.9 in) by 0.3–1 cm (0.12–0.39 in), bulbous-rooting or club-shaped. the top portion of the stem is deep blue, the colour fading towards the whitish or ochraceous base, strongly fibrillose, dry, hollow, fragile, often twisted. the flesh is blue in the cap & the upper parts of the stem, but whitish or yellowish at the base."

What advice would you give to someone who is going into microbiology ? Love your blog 😺

thank you! 🫶🏻

for someone going into microbiology, i’d definitely recommend putting effort into your chemistry courses, especially if they’re not your strong suit (i’m not very good at chemistry)

also, take any lab experiences that you can get, even if they’re not micro! any time that you can get into the lab and get your hands dirty (metaphorically speaking) will help you develop your skills!

A microscopic spectacle: these diatoms (Bacillaria paxillifer) slide parallel to each other in large colonies. I can only speculate as to why, but I imagine it is a method to access sunlight for photosynthesis while also providing a quick route to safety. 250x magnification, 4x speed.

Watch what happens to Germs when you wash your hands with Soap at microscopic level. 🔬 The Soap molecules surround germ cells and disrupt their cell walls, causing them to burst.

Germ cells are surrounded by a cell wall that protects them from the environment. This cell wall is made up of a layer of peptidoglycan, which is a polymer of amino acids and sugars. Soap molecules are made up of two parts: a hydrophobic (water-fearing) tail and a hydrophilic (water-loving) head. When soap is added to water, the hydrophobic tails group together and the hydrophilic heads face outward, forming micelles. These micelles can surround germ cells and the hydrophobic tails can then disrupt the cell walls, causing the cells to burst.

The hydrophobic tails of the soap molecules can disrupt the cell wall in two ways. First, they can bind to the peptidoglycan molecules and weaken the bonds between them. Second, they can create holes in the cell wall. Once the cell wall is disrupted, the germ cells lose their internal contents and die.

It is important to note that soap only works to kill germ cells that are surrounded by a cell wall. Germ cells that do not have a cell wall, such as viruses, are not affected by soap.

The size of the soap micelles is important. Micelles that are too small will not be able to surround the germ cells. Micelles that are too large will not be able to penetrate the cell walls.

The concentration of soap is also important. A higher concentration of soap will be more effective at killing germ cells.

The temperature of the water can also affect the effectiveness of soap. Soap is more effective at killing germ cells in warm water than in cold water.

I hope this post has helped you understand the importance of handwashing and why doctors always ask you to do it regularly. Washing your hands with soap and water for at least 20 seconds is one of the best ways to prevent the spread of germs and stay healthy. So please, wash your hands often and help keep yourself and others safe!

Thank you for reading this post. I hope you found it informative and helpful. Please share it with your friends and family so they can learn about the importance of handwashing too. 😊🙏
