Jelly Fungus

A black jelly fungus, probably either Exidia glandulosa or Exidia nigricans, on a twig from a broadleaf tree.

The spores are curved sausage shape (allantoid) and about 15 x 4um.  This is consistent with the 14–19 x 4.5–5.5um quoted for E. glandulosa and for E. nigricans (these two species are indistinguishable under the microscope).  The above image is x600 and is about 86um wide.
