The apothecia of this last series show a close resemblance to theperithecia of certain Pyrenomycetes, and, as far as their mature structureis concerned, they may be placed as logically in one group as the have we at present any information with regard to development whichcan decide the question. It remains even possible that the Hysteriales area transition series and that some of the forms group
