![]() ![]() The activity allows students to understand the work of a mycologist. Ask the students to explain what kind of work a mycologist does. Start the lesson by having the students watch the video. Mycelium (plural: mycelia) – the vegetative or non-reproductive part of a fungus made up of a collection of thread-like tubes (or hyphae). Hypha – (plural: hyphae) a thread-like tube that forms the body (or mycelium) of a fungus. Spores are extremely resistant to environmental damage and can grow into a new organism. Spore – a small, single cell responsible for reproduction by certain organisms. Instead, they dissolve and absorb their food. Fungi lack chlorophyll to make their food. Glass cups or bowls large enough to cover mushroom capsįungus – (plural: fungi) an organism from the Fungi kingdom that is separate from animals, plants, or bacteria. Students also will learn that by comparing spore prints, they can identify different mushroom species.ģ – 4 different kinds of whole fresh mushrooms (preferably gill mushrooms) Students will learn to create spore prints of mushrooms and label and preserve their spore prints, just like a mycologist. ![]() Through observation and discussion, students will gain knowledge of the basic anatomy of mushrooms, their life cycle, and their method of reproduction through spores. In this lesson, students will be amateur mycologists–collecting and analyzing various mushrooms. All over the world, mushrooms also are cultivated for human consumption. Fungi also are responsible for the production of beneficial drugs such as penicillin, and of fermented foods such as breads, wines and cheeses. Fungi play an important role as decomposers, breaking down organic matter and recycling nutrients. Mycology, the study of mushrooms and other fungi, has helped increase our awareness and understanding of fungi and how they affect our daily lives. Mycologist Roy Halling walks us through the wide world of mushrooms and takes us on a fungi foraging foray on the grounds of the New York Botanical Garden in the Bronx. Coupled with a still air box (which will prevent airborne contaminant from landing on the grain) this method can yield great results.From death caps to puffballs, the fruiting bodies of fungi can be grouped into about a dozen major categories. Growers do this to ensure that the risk of contamination from the spawning culture is lowered as the mycelium will have fought off all contaminants in the Agar medium. If you want to use grain spawn and do a bulk grow it is recommended to go from spores to agar as discussed in the previous section. Inoculate grains inside in a “still air box”.If you decide to do Spore to Grain (which I don’t recommend) you need to: However some people are using uncle bens tek with success which technically is a spore to grain procedure. Unless your spore syringe is made under perfect sterile conditions using it on grains is not the best method. However, the chance for contamination with grain is greatly increased. Using your spore syringe with the grain is a simple concept, possibly as simple as PF-tek. Fruiting – The mycelium is moved into fruiting conditions wherein the mushrooms grow out from the myceliated substrate.Incubation – Mycelium which has developed from the spores begins absorbing nutrients from its surroundings, growing at an exponential rate and completely overtaking the substrate.Inoculation – Spores are introduced into an appropriate growth medium created in the preparation stage that the mushroom mycelia can breakdown and absorb.Preparation – Mix the substrate then sterilize or pasteurize before use.The process can be briefly broken down into the following steps: To do this successfully competing molds and bacteria must be removed from the environment allowing the mycelia to dominate the growing spaces. Next, this mycelia will then expand moving along the mushroom life cycle until it fruits, producing mushrooms. In short, to grow mushrooms from spores you must first germinate the spores in a sterile environment with a growth medium that the mushroom mycelia can breakdown and absorb as nutrients. I remember when I first started growing mushrooms this all seemed very complicated but once you learn the different terminology and processes it becomes worlds of fun. I’ve decided in this post I will clear this up for you and outline options for using the spores. To complicate things further there are several different products such as “Spore Prints”, “Spore Syringes”, “Liquid Cultures”, “Grain Spawn” which are sold to get you started and you are not sure what you require or how to use them. So you’ve decided you want to try your hand at growing mushrooms but you’re unsure exactly what to do with the “Spore” products that various growers are selling online. ![]()
