That didn't sound too right for me (but my biology knowledge is dated at this point) so I read the relevant section from that page. It concludes wiht:
"""The delayed fungal evolution hypothesis is controversial, however, and has been challenged by other researchers, who conclude that a combination of vast depositional systems present on the continents during the formation of Pangaea and widespread humid, tropical conditions were responsible for the high rate of coal formation."""
It's interesting to think just how much went on before trees with lignin showed up. Flowers are also relatively recent - 150mya.
