Rhodophiala radicle emerging in water --

[petershaw]

I tried the water germination method for the Rhodophiala bifidum seeds and as you can see the radicle has emerged from many of the seeds.

Should I wait until the cotyledon shows up or ?

AKA Rhodophiala?
It's best to plant the seed as soon as you see the radicle.  You run the risk of breaking the root otherwise.  Cover the seed with about 1/4 inch (1 cm, more or less...) of soil.

Thanks, thats exactly what I did, 
Rhodophiala is correct

When the radicle gets quite long and fragile I put a layer of sand deeper than the radicle length over the substrate in a container, and stand it in water the depth of the new surface. It is very easy to put the long radicle into the quicksand without damaging it. Then I drain the surrounding container, and the sand settles in around the radicle.
