1 Harvey’s plate gives one magnified filament with a stalked oogonium and 
another with a sessile one. The former is almost certainly V. sphaerospora, but 
the other may be V. Thuretii , although there are no antheridia figured, these 
being usually present on the same, or a branch of the same, thread.
