Fixed fungus studies.

Fixed name mapping, and for a few had to root/re-root trees. There may be more errors (e.g. rooting) but I don't know the groups.

Inferred named ingroup nodes are listed in the file 'fungal_all.py'. All seem to be fungal.

It is a bit worrisome when within a study (e.g. 387) different trees have different ancestral nodes.
Sometimes this is because of different sampling (fine), but sometimes 1) different rooting or 2) different specified ingroup.
Perhaps Romina could look these over to make sure things fit?
