Nice Collection — Myxacium, Section Defibulati…

Nice observation Christian. Very key point was to look for clamps on the pileipellis for these big Myxacium. You will also note that this one is clearly clampless and they tend to have spores that are lower aspect ration than typically for C. collinitus/trivialis. Our most common member of this group is C. vanduzerensis, but this one shows lilac colors on the cap, thus appears something very interesting. Please preserve.

Those are probably real clamps.

The ones I saw were not attached to both long cells, just a curved spur arching off of one cell.

Love your microscopy!

Hey, so are pseudoclamps those liitle teeny connector pieces between those long cells , (Like a little patella between a femur and a tibia?)
