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.
