[1] There are few reports of _Ascozonus_, apart from _A. woolhopensis_.
Observed spore sizes of _A. woolhopensis_ suggest that measurement of
Renny's (1874) illustrations of spores leads to values which are too
large (19-20 × 6-6.5µm). Those in parentheses are what they might be,
based on the discrepancy between observed values for _A. woolhopensis_
and Renny's illustration.
