Tiny fungi

I first noticed these in January, they're on the trunk of a living tree, our Japanese cherry. Last week I was looking if there were any again and saw none, today there are many, I think at least twenty. Can't ID them, always difficult with fungi, slime and lichen. They have no stem , are off-white, with a furry hat and a line spore bottom. The biggest have a diameter of about 1 cm (about 0.4 inch). For Tiny Tuesday with thanks to Sheol for hosting :-)

Thanks very much for the kind comments, stars and even two hearts for yesterday's family keepsake glasses.
