More Agar Help Needed
    #518113 - 01/12/02 04:18 AM (15 years, 8 months ago)

I am following the multispore mycellium agar culturing tek which can be found in the grow/find section of the shroomery. Can anyone provide me with a link where I can see a photo of sectoring in a petri dish? I am trying to find the difference between rhizomorphic and tomentose growth. The only description is that the former is "strandy" and the latter is "cottony". My predicament is that I have what looks like robust white (and what I would call cottony) growth in the center where I made the original innoculation, and all of the radial growth from the center of the dish is very very fine strands. Which is which? Please help.

go to amazon.com
type in mushroom cultivator
click on link to see book cover
click on link to enlarge photo
the middle pic is what you want. that photo is of achunck of mycelium that has been transferred at least a couple times. since you just germinated your spores on your first dish, it is unlikely that it is very rhizo. it is possible if is grown out quite a bit but it usuallly takes a transfer or two. it doesnt mean you wont get mushies if you got to spawn with it, its slower growing though and less productive. if you have some extra bucks, grab yourself a copy of TMC, best book youll buy. g'luck.

this is a chunk of rizomorphic mycelium

as you can see the m. grows radially from the inoculation point, in this case this is a pure culture, meaning that all the mycelium have the same properties.
When you're going to sectoring you should look to parts in the petris where the mycelium look like the pic above, cut the part and inoculate a new petri, repeat the process until you got what you want.
