Jelly Fungus

A jelly fungus, probably Exidia thuretania, growing on a fallen twig. Myxarium nucleatum is similar but tends to be clearer and often contains white nuclei.

I took the following specimen:

Which yielded the following spores (magnification x600, field width 86um):

These average about 16 x 5.5um which agrees with the 13-18 x 5.5-7um given for Exidia thuretania but is a bit larger than the 8.5-14 x 3.5-5um given for Myxarium nucleatum.

First photo and specimen taken in Whiteknights Park, Reading, UK, on 2014-02-01.
