The paper of Wodniok et al. BMC Evolutionary Biology 2011, 11:104 states the latter, do you know any new studies on this matter?
Maybe these ones can help you a little, they also point to Zygnematales (alone or with other group) as the sister group of Embryophyta.

Genetic strands show monophylactic evolution, an evolution that is based on chromosome numbers, that was increased in response to environment through polyploidy, it generates unique sequences, that present homologies (less than 50%), differences more than 50%. But near homologies stand as sister groups which are matcheable with other individuals of a same species as well as minor hmologies with other. Embryophyta is a sister group. Zygnematales give rise an species from the parental strand. Plant evolution is based on three important aspects 1. phytochromes 2. cytochromes 3. morphogens, second from marine to terrestrial life many new genes appeared in plants, first were the algae, second bryophytes, there must be category in between.
In one hand genetics propose the closest relatives of land plants to be either Coleochatales or Zignematales; on the other hand, morphology and sex biology points to Charales. Land plants and Charales share the following characteristics (not shared with Coleoch. and Zignemat.): body divided into nodes and inter-nodes, big sized bodies, apical meristem, and male and female gametangia.
