NOTES
Hypoxylon elevatidiscus
posseses ostiolar discs, a carbonaceous stromatal layer discretely enclosing
each perithecium, and a thickening on the ascospore perispore, and is thus
placed in section Annulata of Hypoxylon. After gradually
displacing the overlying stromatal tissue, the ostiolar discs bulge, become
convex, and leave the disc rims lower than the convex disc surfaces. In other
taxa of section Annulata the discs are located below the rims. It is by
this characteristic that H. elevatidiscus differs from the other
taxa of section Annulata.
