The physiognomy and the species composition of the Salici cinereae-Sphagnetum recurvi (Zólyomi 1931) Soó 1954 are variable in Hungary. This association has been divided into two new subassociations by the authors, due to the slight differences in their moss layer. As a representation they compared 27 phytocoenological relevés, made by 4 different botanists in 10 different mires, by multivariate analysis. Those peat moss dominated willow carrs, in which the dominant moss species are Sphagnum squarrosum and/or Sphagnum fimbriatum subsp. fimbriatum, are called Salici cinereae-Sphagnetum recurvi sphagnetosum squarrosi subass. nov., on the contrary those, in which any species of the Sphagnum recurvum agg. (S. fallax, S. angustifolium, S. flexuosum) and/or Sphagnum palustre are dominant, are called Salici cinereae-Sphagnetum recurvi sphagnetosum recurvi subass. nov. The two submitted subassociations of peat moss dominated grey willow carr are very similar. They could be found together or independently, on a terrestrial or on a floating mire. All of them are a part of the successional series of mire development, which can result a continental raised bog under recent climate, too.
