Examination of the bark of living trees for representatives of the order Myxobacterales (Schizomycetes) has resulted in the finding of several previously undescribed species. Four such species of myxobacteria, Stelangium vitreum (Family Archangiaceae), Podangium cylindricum and Podangium alboracemuin (Family Polyangiaceae), and Angiococcus moliroseus (Family Myxococcaceae), are described and discussed in relation to previously reported species.
