Observation 140513: Physarum pulcherrimum Berk. & M.A. Curtis
When: 2013-07-21

Notes: Very dark myxos on sodden log – Under the magnification of an SLR turn out to be magenta Physarum-like globes on deteriorating stalks – none appear to be split open and releasing spores – instead a number are succumbing to a white mold that has also jumped onto an adjacent Stemontis. Where visible (see photo #5), the top quarter of the fb is a darker magenta that the rest.

The last 5 photos were taken approx. one month later on August 25. Most appear the same with intact fructations and advancing mold, but a few can be seen with broken or split peridium.

Used references: Frederick W. Spiegel, Professor, of Department of Biological Sciences at University of Arkansas suggested this name in an email today. P. pulcherripes is not supposed to be as pink/fuschia as what you show. I also think the fructification you show may be very fresh, so mature spores and capillitium may be limited.
