Dear Everyone - just two clues to get! First off, 8 down:
'edible fungus is, to a greater degree, lunch starters.' It has 5 letters and the ones I have are: - - R - T
Then there is 12 across, 'it is photoelectric and might bring all closer to energy production.' Two words - 5 letters and 4 letters. I think the first one is 'solar' but the second one I'm not sure of. Therefore any help at all would be most gratefully received!
