My apologies for the silly non scientific title, but I don’t know which species I have here and it sounded kind of catchy. They are definitely of the Genus Comatricha as after they matured I was able to find the spore mass entangled in a web of pale brown threads similar to genus Stemonitis. They are defiantly in the fructification stage, but nearing the end, by the looks of it. A very lucky find at this stage. The middle image is another pair in the cluster with only one exhibiting the strange cap. The round overexposed white spot on the right subject was a bubble of clear liquid of unknown origin. The bottom image is my attempt to show the thread structure after a majority of the spores have escaped. Heavily tent lit to take out the shine it exhibits some off color but the thread network is visible in the stack. This is best seen under the microscope. A subject for a future post in the other forum.
