Abstract
The tips of the rhizomorphs ofSphaerostilbe repens transferred on agar medium regenerate some aggregated organs without an intermediate mycelium stage Each extremity of the drawn rhizomorphs can give rise to eoremia on its air face and to rhizomorphs on the contact with tho culture medium These heterogeneous environmental factors impose polarized regeneration easily inverted upon the rhizomorphs Nevertheless a residual and stable polarity remains it is attributed to the apex which is more capable of bearing new organs than the other extremity Tho efficiency to regenerate depends on the ago of collulos and on tho size of tho rhizomorph tip howover it is very difficult to provent the formation of new aggregated organs
