possibly hymenochaete tabacina?

How about H. rubiginosa?
there were no brackets or virtually none, just this crust all over the log.
I'll back H. tabacina then... "A crust which partially turns up to form small brackets, the fruit bodies can join together to form quite large (10-25cm) patches. Normally tobacco brown often with light edges, ochre- grey when old. Minutely hairy but you will need a x10 lens to observe it." - Rogers Mushrooms
