not terribly relevant

but interesting:

http://www.ut.ee/ial5/fce/fce47pdf/fce47_parmasto-clav.pdf

coralloid members of the Hymenochaetales (or Hymenochaetaceae, depending on whether or not one accepts Clavariachaetaceae as a family). All are xanthochroic, but alas, smooth, “elipsoid to almost subglobose” spores.

As a sidenote, I suspect that the presence of Thelephoroid spores not a character exclusive to the genus Thelephora

I do all the time

as does Alan, apparently. KOH+ vs KOH- is a major key break in sorting out polypores. were it not for the micro, I would think this was something in the Hymenochaetaceae. can’t remember where, but was just reading about the few genera/spp. outside that family with xanthochroic (black in KOH) tissues…

not what i meant…

i just think that, so few people test w/ KOH that it is probably, poorly documented…if these even are documented.

if by that

you mean diagnostically insignificant, I beg to differ.

i highly doubt…

that is a chemical reaction thoroughly documented or described…

that they do.

but what Thelephora are black in KOH?

spores…

look like Thelephora to me…
