Starting season no. 5 and my wood still sizzles alittle

Went into the woods today to see what needs to be cut! and looks like at least a few cords worth to be done.Did some cutting also today with the chainsaw!mostly small stuff.Again its alot of oak with some Birch and maple mixed in.Not as young as i used to be so i will do a few hours max each day i get out there.A question for you wood burners! Most of the time after i burn the last load of the night when the fires out the next day i end of with coal size or larger pieces of burned wood! should it be just fine ash after a burn or am i dampering the stove abit too much for that last burn of the night.

A Question! Whats your opinion on burning wood that is solid but lots of mushrooms growing on it.

burn it mushrooms are just extra btus!!
