Oyster mushrooms!! 》 Pleurotus ostreatus

Gorgeous flush of oysters on campus!!!

I had seen some strange but similar fellows here last semester and IDed them as funnel woodcaps or perhaps linx paw oysters due to their fuzzy stems, but these dont appear to be quite the same species.

The president of the school stopped and chatted with me about them. She asked twice if my observation was related to my major. Nope, just my special interest. 😅

do you know much about mushroom cultivation? if so, would it be feasible to have an isopod colony living inside a mushroom grow tank like a monotub? both are generally kept humid and warm, and the isopods could eat the mushrooms and when the isopods die the mushrooms could eat the isopods. and there'd be cool mushrooms and cool bugs like next to each other. it would be beautiful.

I have very limited knowledge of fungus cultivation, but I do know that the “mushrooms eat isopods” bit would not work here. isopods like eating each other much more than mushrooms do, and will do that much faster. unless something is horribly wrong, isopods do not leave any evidence of their dead.

I also do not think mushrooms are a complete diet for isopods, who need a plant-based diet of leaves (and less so wood). you would need to provide them with leaf litter + veg/protein treats even if the isopods did want to eat the mushrooms or the mushroom growth media (which might well be more edible to them than the fungus).

I still think the idea would be feasible if you used mushrooms as more of a decoration, and picked something very hardy like Pleurotus that can eat whatever junk you grow it on. build a normal isopod tub, but bury a plug of inoculated mushroom spawn in the substrate somewhere, and if you keep the soil moist you’ll probably get some mushroom/isopod cohabitation going on.

also, don’t keep isopods warm unless they’re tropical species. most of the common varieties are native to cold areas of Europe and weather freezing temperatures most of the year. I find all of my species breed best at about 70F° or slightly under that.

what's the most recent mushroom fact you learnt??

THANK YOU FOR ASKING THIS !!

carnivorous fungi : fungi that derive some or most of their nutrients from consuming microscopic or minute animals.

most of these species trap & stun nematode worms (pictured below), making them nematophagous organisms.

other carnivorous fungi may attack amoebae or collembola (pictured below).

fungi trap & eat these tiny animals in two main ways :

constricting rings (also called active traps)

adhesive structures (also called passive traps)

some fungi have a profound ability to "sense" when a nematode worm is near before activating their "traps". scientists are unsure how they evolved this ability without proper brains.

in total, there are about 150 species of fungi that attack, kill & digest animals.

a good example is pleurotus ostreatus (pictured below), which uses a calcium-dependent toxin to paralyse its prey (nematode worms) within minutes, & leads to necrosis of the miniscule animal. it acts as quite a protein-rich food source !!

another fun fact : i used to farm these at home :-)

[mycochaotix]

“The life cycle of most basidiomycetes encompasses two distinct phases: those of the monokaryon and the dikaryon. Initially, a meiotic haploid spore germinates, giving rise to a mycelium with uninucleate cells, the monokaryon. This mycelium can grow vegetatively and, when it meets another monokaryon of the same species, hyphal fusions occur between the two mycelia (figure 1). At that moment fertilization of the mycelium can occur. In most mushroom-forming basidiomycetes, fusion is followed by exchange of nuclei but not cytoplasm [7,8], resulting in a mycelium with binucleate cells, the dikaryon. Nuclei migrate from the contact zone through the whole receiving mycelium [9]. The exact process of dikaryotization is unknown, but it must involve many nucleus duplications because the outcome of dikaryotization is that all cells of both receiving mycelia contain both nucleus types (figure 1b). Just like the monokaryon, the dikaryon can grow vegetatively, but it is also able to form sexual fruiting bodies (the mushrooms). In the fruiting bodies, the two nuclei fuse, directly after which meiotic spores are produced. A dikaryon can no longer accept other nuclei, but it can still donate nuclei to a monokaryon [10,11], a phenomenon called the ‘Buller phenomenon”

“The primary mycelium (monokaryon) of basidiomycete fungi, growing from a germinating sexual spore, is hermaphroditic, but it loses female function upon the acceptance of a second nucleus. The resulting dikaryon with two different nuclei in each cell retains a male potential as both nuclei can fertilize receptive mycelia. “

“Sexual selection is expected to occur during a dikaryon–monokaryon (di–mon) mating because both nuclei (analogous to male gametes) of the dikaryon are able to fertilize the receiving monokaryon (analogous to the female gamete)”

“The monokaryotic and dikaryotic conditions can be distinguished by the presence of clamp connections in dikaryons and their lack in monokaryons. Clamp connections are hook-shaped structures involved in equal nuclei sorting to the daughter cells produced by mitosis.”

If characters on AMC IWTV were mushrooms, what would they be?

Omg.

So my immediate thought was that Lestat is a chanterelle, because he's ginger and because I always assumed that was a French name. Doesn't it sound like it's related to "chanteuse" or something?? But I just googled it and apparently it's Greek in origin, which is dumb. Whatever, Lestat is a chanterelle.

Louis is Pleurotus ostreatus, the oyster mushroom. Stunning, beautiful gills and a choice edible, but man, so clingy. RIP to the tree it decides is the love of its life

Claudia is a baby Amanita virosa, a fool will be like "Oh wow is this a delicious Agaricus mushroom? Let me have a taste" and die of multiple organ failure because obviously it was a Destroying Angel species

The oyster mushroom (Pleurotus ostreatus) is a staple of many kinds of cuisine, prized for its mild flavors and a scent vaguely hinting at anise. These cream-colored mushrooms are also one of several types of carnivorous fungi that prey on nematodes (roundworms) in particular. The mushrooms have evolved a novel mechanism for paralyzing and killing its nematode prey: a toxin contained within lollipop-like structures called toxocysts that, when emitted, cause widespread cell death in roundworms within minutes. Scientists have now identified the specific volatile organic compound responsible for this effect, according to a new paper published in the journal Science Advances.

Carnivorous fungi like the oyster mushroom feed on nematodes because these little creatures are plentiful in soil and provide a handy protein source. Different species have evolved various mechanisms for hunting and consuming their prey. For instance, oomycetes are fungus-like organisms that send out "hunter cells" to search for nematodes. Once they find them, they form cysts near the mouth or anus of the roundworms and then inject themselves into the worms to attack the internal organs. Another group of oomycetes uses cells that behave like prey-seeking harpoons, injecting the fungal spores into the worm to seal its fate.

Other fungi produce spores with irritating shapes like stickles or stilettos. The nematodes swallow the spores, which get caught in the esophagus and germinate by puncturing the worm's gut. There are sticky branch-like structures that act like superglue; death collars that detach when nematodes swim through them, injecting themselves into the worms; and a dozen or so fungal species employ snares that constrict in under a second, squeezing the nematodes to death.

The oyster mushroom eschews these physical traps in favor of a chemical mechanism. P. ostreatus is what's known as a "wood rotter" that targets dead trees, but wood is relatively poor in protein. Its long branching filaments (called hyphae) are the part of the 'shroom that grows into the rotting wood. Those hyphae are home to the toxocysts. When nematodes encounter the toxocysts, the cysts burst, and the nematodes typically become paralyzed and die within minutes. Once the prey is dead, the hyphae grow into the nematode bodies, dissolving the contents and absorbing the slurry for the nutrients.

OYSTER MUSHROOMS

Oyster mushrooms are beloved the world over for their delicate texture and mild, savoury flavour. The cap of the mushroom is convex and shell shaped, when opening out they flatter with waves and sometimes have split edges. they are usually smoky grey, silver and brown. The gills are crowded and white however as it goes down the stem it turns slightly yellow. The stem is white and opens out to the cap. finally the flesh of the mushroom is white and tough in the stem.

The Oyster Mushroom has some amazing properties one of which is that it is a carnivorous mushroom which traps and ingests nematode worms to provide it with nitrogen and other useful chemicals. The species of genus Pleurotus contain statins which are thought to help reduce cholesterol. Another is the fact that they have the ability to clean up pollution by hydrocarbons like petrol and oil which is quite incredible.

This specific type of fungus stood out to me as I really liked the look of the gills. I wanted to choose fungus which allowed me to generate the most ideas and oyster mushrooms allowed me to do this. the ideas that I have so far are pleats and experimenting with multiple textured fabric techniques. as for my illustration I am going to experiment with different shapes and silhouettes. I plan to create a double pages spread for this type of fungi in order to extend my research further.

Report frassini (Fraxinus excelsior)

Lombardia, 12/03/2023, 200[m]

I frassini stanno lentamente risvegliandosi. Alcuni hanno le caratteristiche gemme nere del frassino maggiore ancora chiuse, altri esemplari le hanno ormai rigonfie e pronte a fiorire, altri ancora hanno ormai i primi fiori nello stadio iniziale del loro sviluppo...

Le infiorescenze del frassino non sono particolarmente vistose né adatte a uno scopo decorativo/ornamentale, ma è molto importante per un fungaiolo saperle riconoscere!

Ho osservato che alcune gemme sono un po' secche perché stanno patendo la mancanza d'acqua e di umidità. Il terreno è abbastanza secco, specie nelle zone esposte, e i piccoli corsi d'acqua sono asciutti: la siccità si fa sentire. Ma pare che quest'ultima ci abbandonerà nella notte a cavallo tra martedì sera e mercoledì mattina. Se le precipitazioni fossero confermate allora la stagione delle Morchelle potrebbe iniziare sotto un buon auspicio. Ricordiamoci che si parte dalla pianura, dove le grandi precipitazioni concentrate in poco tempo hanno un effetto molto più benefico rispetto alla montagna, dato che l'acqua si accumula sul terreno e non scivola via (una parte defluisce subito verso i corsi d'acqua o le pozze ma quantomeno l'assorbimento è maggiore).

Non saprei quantificare quanto tempo rimane da attendere prima di trovare le prime Morchelle. I frassini si stanno attivando ma ciò che manca, per ora, è la temperatura adeguata, che non dovrebbe scendere sotto i 7°C e superare almeno i 15°C per un ragionevole lasso di tempo. Manca anche un adeguato tasso di umidità, che dovrebbe ristabilirsi mercoledì se le precipitazioni fossero confermate.

Nonostante le temperature piuttosto miti per la prima metà di marzo, non ho trovato funghi primaverili, ma solo un vecchio Pleurotus ostreatus e dei funghi della famiglia dei Coprinus (tipicamente nella fase deliquescente). Probabilmente questo stallo non è tanto dovuto alle temperature quanto alla penuria d'acqua.

Comunque, la primavera è alle porte e con lei anche la stagione dei funghi! Prepariamoci al nostro meglio: controlliamo in anticipo la nostra attrezzatura - ad esempio mi sono accorto che devo sostituire un laccio degli scarponi che, se si rompesse, renderebbe le mie camminate estremamente scomode se non impossibili. Organizziamo gli impegni in modo da non accavallarsi troppo con il tempo libero da dedicare alla raccolta dei funghi.

Un saluto e a breve altri aggiornamenti...

Sabato 18 marzo

I frassini sono quasi tutti in fiore, la maggioranza... Tra una decina di giorni si dovrebbero aprire le danze, un po' d'acqua non farebbe male...

[nomuscariahere]

Was determined to find my first Pleurotus this winter, and lo and behold! It was right on the trail, quite conspicuously. Oddly this species wasn't listed in my guide (so probably a rare or uncommon find in my area), but likely P. dryinus/levis. Note the veil remnants on the edge of the cap.

Second find of the day is Auricularia fuscosaccinea. At least, that's what I called it on mushroom observer and no one corrected me. So it has to be correct right? This belongs to a group of species more commonly known as wood ear.
