'wood lovers agar'

Rush Wayne suggests adding 'wood pellets' (which presumably break down during sterilisation) to to a MYD agar mix...
I can't get the pellets here, but I do have some suitable rough sawdust I plan to use as substrate... I was wondering if I could perhaps make a 'sawdust tea' (boil a cup or so for 1/2 an hour and save the liquid) as the liquid base for a wood lovers agar mix.
Also, I can't get malt (or yeast extract ), so I was planning on trying potato/dextrose (read table sugar) with some of my 'sawdust soup'...
Any suggestions? (please keep in mind that I live in a country where I can't read the labels on anything to see if there are additives or not... )

You don't have to make a tea from sawdust - just put few grams of sawdust in the agar. That should work. Dextrose is not the same as table sugar. It's good to add some simple sugars like dextrose, fructose or maltose in the agar. If you can't find anything like that use honey!

Yup the wood pellets are jus compressed sawdust. When you pour hot water on them, they dissolve.
DFA - 1 litre water 20g agar 20g dry dog food
I would add the wood also.

karo syrup is dextrose. I usually add a couple grams of whatever I'm going to grow on to my agar, wbs, sawdust, straw etc. The myc is then prepared for the substrate and colonization is sped up quite a bit.

karo syrup is not dextrose. I believe it contains more fructose than dextrose, yes it is interchangeable, but no it is not dextrose. (pure)

Sucrose (table sugar) works fine as well. I've tried it with numerous species and had no problems.

The wood tea agar works very well at sorting what species will like your wood
Ive been testing woodlovers on eucalyptus sawdust and seen vast differences between the species and between isolates
For example the Pleurotus autralis (native) did very well, as did some shiitake strains, while others lagged. The lions mane didnt respond very well at all. This corresponds to the effects ive been getting when trialling these species on supplemented Eucalptus sawdust blocks
I also had zero contamination on the Tea agar. The Eucalyptus phenols and oils seems to inhibit all the moulds and bacteria, of course it also inhibited many edible fungi Im using a Eucalyptus species milled locally (there are hundreds of species) that they annoyingly just call 'hardwood'. But ive seen the forests it comes from and this is a very widespread species so i should be able to get the species name easily
anyway point to that is that not all eucalyps are equal. E globulus and E saligna (bluegums) work much better than Rivergum (E camaldulensis) . Stringybarks are also good (E marginata)for shiitake. To find out all this would take years and years and lots of $ to get large volumes of sawdust shipped in from all over. Using Tea agar we can screen potential species much faster and more cheaply.
