Here are some photos of the (surprise) Cylindrical spores. 6 × 2µm. The body was rubbery and the flesh tasted a tiny bit bitter. A drop of KOH gave a very weak pale yellow reaction ( 4th pic, right side).
After several days of dry weather and also it being late in the evening the weeping had largely stopped.

the two mushrooms may both be “soft” in youth…

but they have a decidedly different feel to them: the Ischnoderma is thickly gelatinous like a Fistulina and the Tyromyces feels like thick cotton batting.

doesn’t rule out Ischnoderma.

It wasn’t soft. I don’t think. I ’ll go back later in the week and poke it.

then Tyromyces is a possibility.

Only dripping Polypore I know of is Ischnoderma resinosum

And I don’t think this is it: liquid wayyyy to white, not at all the amber-color of I. resinosum. Maybe something new? Try to collect a specimen next time, please.
