I've thought it over a while and came to this conclusion. Since there are
some Zygomycete and Basidiomycete yeasts beneath the common Ascomycetes, my
/more fungi /lots of fungi
Fungi -even more fungi -mushrooms (mnjam) -...
\yeasts \some more poor yeasts -
To say it short, yeasts are just degenerated filamentous fungi!
(Sorry to al "yeastists"!)
Warning: This sketch isn't based on any rRNA sequences. It is in fact
the somewhat eccentric view of an molecular biology PhD candidate working
with a filamentous fungus and not with yeast.
