If the body is spread out and microscopic, how do mushrooms grow so quickly? There are two basic reasons: 1 Since they store up compounds between fruiting and most fruit once a year, they have a lot of reserve available to support the mushroom. Plants and animals grow through cell division - to get bigger they have to produce more cells. Cell division is relatively slow and requires a lot of energy. The mushroom body also grows by cell division. However, the mushroom fruit does not grow by cell division.
Just about as soon as it starts to develop, a mushroom has almost the same number of cells that the mature mushroom will have. This means that the cells can balloon up very rapidly. Very little energy is required, basically the cells just enlarge with water.
So a mushroom can increase in size as fast as water can be pumped into its cells. Almost overnight a mushroom can go from a pin head to a large mushroom. Click for Mushroom Life Cycle. Mushrooms need water for their fruit to "grow". That is why a saucer and a humidity tent is included with Mushroom Kits TM. Mushrooms have no skin so they can lose water to the atmosphere very easily. That is why they grow in high humidity lots of water vapor in the air conditions.
If the humidity is too low the cells lose water faster than it can be "pumped" in and the immature mushroom dries up and dies. Mushrooms love all the water they can get? Mushrooms need to breath just like humans do, except they do not have lungs.
Mushroom cells exchange gases directly with the atmosphere. If the body of the mushroom is submerged in water it is comparable to drowning. No oxygen can be exchanged, anaerobic bacteria bacteria which do not need oxygen to thrive build up, and the mushroom is choked to death. It is almost the same with the mushroom fruit. If it is too dry they lose too much water and desiccate.
However, if it is too wet - the humidity is too high - the excess water prevents any gas exchange and the developing mushroom chokes off. Growth rates. Like most organisms without thermal regulation they can not control nor maintain their body temperature , mushrooms grow faster when it is warmer. Try measuring the growth rates of the same variety of mushrooms in a Mushroom Pot at different temperatures. The Trumpet Royale Mushroom Kit produces a good mushroom to work with.
Once the pinheads young mushrooms that look like a fat white pencil tip form, you could measure the length of the young mushroom every 4 or 8 hours. If you measured growth rates at 60 F, 70 F, and 80 F would find a marked difference in growth rates. If the temperature is too low, the mushroom will grow very slowly or not at all. If the temperature is too high, most likely the mushroom will die. A mushroom produces spores instead of seeds.
Fungi are sessile immobile. Sexually produced spores are created in the sac. Sac fungi usually reproduce asexually and sexually. Most sac fungi are multicellular.
Mostly all sac fungi are useful to people. Club fungi are the kind of fungi that you see that looks like an umbrella. Other kinds of Club fungi are puffballs, smuts, and rusts. During sexual reproduction special hyphae create and make club like structures called basidia.
Sexual spores are created in the basidia. Imperfect fungi pretty much include all types of fungi that do not fit any other types of fungi. They do not reproduce sexually. Most of them are parasites that cause diseases in animals and plants. Some types of fungi are parasites. They get their food by growing on other living organisms and getting their food from that organism. Other types of fungi get their food from dead matter. These fungi decompose, or break down, dead plants and animals.
Fungi reproduce by letting out little spores from itself. When the spores are released into the air, it is taken by the wind to somewhere. That is where the next generation is started. Fungi decompose all the dead animals and plants. Without them doing that, the world would be littered and polluted with all the dead animals and plants lying around.
Some other fungi are used to make medicines, like Penicillin. Microscopic view of mycelial threads, which are only a few thousandths of a millimeter in diameter. A mushroom is the reproductive structure produced by some fungi. It is somewhat like the fruit of a plant, except that the "seeds" it produces are in fact millions of microscopic spores that form in the gills or pores underneath the mushroom's cap. The spores blow away into the wind, or are spread by other means, such as animal feeding.
If they land on a suitable substrate such as wood or soil spores will germinate to form a network of microscopic rooting threads mycelium which penetrate into their new food source.
