I guess I'm off base there Heine. It seemed to me that since
basidiomycetes (fungi with spores borne on basidia) and ascomycetes
(fungi with spores borne in ascii) as well as Termitomyces (termite
mushroom) all having -myces as part of their name, they might well be
fungi as well.

As for what David Hawksworth counts as fungi, I don't know. All I did
was post what Bryce Kendricks had said: a profound few words if ever I
read them.
