Pioneers on a fallen log
Possibly a group of immature volvariella? To give scale to the subject it may help to realize the depth of field here, using the "supermacro" mode, is less than 1 cm deep.
See other mushrooms composed with shallow depth of field.
Update: Ressaure suggests below that this might be a Pluteus on the verge of opening. I checked back the next day and all traces of these little fungi were gone - not even a vestige of stem remained.
