Not only were there major differences in the ectomycorrhizal fungal species composition of pinyons growing in cinder and sandy-loam soils, but also there were differences in the subphyla of fungi involved in the symbiosis at the two site types.
Ongoing molecular and ultrastructural studies will probably necessitate still further redistribution of taxa among the 13 phyla of the present protozoan system and their 26 subphyla. Despite the phylogenetic distinctiveness of the two groups, the phenetic boundary between the Neomonada and Cercozoa is particularly unclear, as are the affinities of the various heliozoans.
It now seems clear that hexactinellids differ substantially from cellular sponges and should be differentiated from them at a high taxonomic level (Bergquist, 1978), as reflected in the subphyla Symplasma and Cellularia proposed by Reiswig and Mackie (1983).
Markl's (1986) investigations were designed to elucidate broad phylogenetic relationships of Hcs representing taxonomic categories ranging from families to subphyla. Because his sample was composed of, at most, a few species per family, the patterns he described may or may not be characteristic of the families.
