Not saying this is the species pictured here…

but in response to Danny’s original question (2nd comment), Thelephora multipartita is reported to turn black in KOH.

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?

look like Thelephora to me…
