K&J REMARKS
The illustrations (pl. 1, figs. 18-19) are not clear and do not show the details of the cellular structure of the specimens as described by the authors. The authors refer to them as "spores," yet compare them with (ascostromata of) Phragmothyrites. Kalgutkar and Jansonius (2000) think that they more readily resemble the setose pycnidia found in some Coelomycetes.
