Nice myxos Ken :)

The first one could be Arcyria incarnata (or major) - I'm just in the process of photographing A. incarnata myself.. not as successfully as you so far..)

The second could be Didymium but you would need to put some of those surface calcium deposits under the microscope and look for star-shaped crystals..

Cheers,

John

Interesting. I did not know that about the crystals, all that I have ever heard made reference to are the spores for positive ID. Like the capillitial image you've included. I have an oil immersion but seldom use it because I can usually resolve most everything, with the exception of spore characteristics, with a 40X dry objective. Thanks for the crystal info, I need to gather some samples and have a look. :D

These would not happen to be oxalates would they? :-k
