Fungi have spores, not seeds and don't reproduce the same way that plants do. Spores- What are they? Most fungi reproduce or make new fungi by producing spores. Each spore is microscopic but when we see them all released at once we can see a fine powder.
Each different type of fungi produces up to billions of spores with there own particular shape, size and colour. This helps researchers to identify the fungi when they look at the spores through a microscope with a magnification of over 400 times. Spores are released when fully
grown or mature from the 'fruit' of the fungi (it is not really fruit like
that from plants). The names for the two groups that
produce larger fungi are Ascomycetes = Shooting spores which includes over
30,000 different kinds like Mildews, Moulds, Cup, Flask, Primitive
Truffles, Morels, Earth Tongues and Caterpillar fungi. Some fungi release their spores from their gills under the cap of the fungi. Boletes don't have gills but have thousands of tiny pores for their spores to come out. These are called polypores. Bracket fungi have pores for their spores too.
Most spores are blown away in the wind but some are eaten by animals and pass through their gut and out the other end to start a new life. Puffballs and earth stars have no gills and release their spores out of a whole that opens at the top of the fungi. Here below in the photo is a soft puffball hole magnified at 60x. Stinkhorns have no gills either so when this unusual fungus is ready to release its spores it breaks through the top to form a horn like stalk. At the top of this stalk is a slimy bad smelling substance which contains the spores. This might smell bad to us and keep us away but it attracts flies that walk in the foul slim and when the flies land on other plants the spores are wiped off to a new home. This fungus is in the Gasteromycetes group and also smells bad and has little winged insects enjoying it. Do fungi have female and male parts? No. Each spore will develop
directly into a fungus in the right conditions not like a seed where the
male and female reproductive parts have to find each other on the flower
to begin a new plant. There are two different
kinds of threads or mycelia in spores from a fungus with different characteristics but can not be
identified as male or female. Spores
of a fungi do not contain an embryo like a seed does and they do not hold
much of a food reserve. Some fungi spores have only one cell like
yeast and other species have several cells. |

Here you can see an Ink Cap left to dry out. The spores are in the middle as plain black. |
Here are the Ink Cap spores magnified 200x. |
Fourth; If you have access to the schools microscopes look at your spore prints under them. Make sure there is plenty of light in the room. Draw what you see through your microscope on a piece of paper.
