Specimen available

Does anyone recognize this Polyporales species from broad-leaf forest in Brazil? On wood. Small, clustered caps 5-10 mm diam, whitish, soft, tough, tomentose, underside with pale tan-greyish pores ab. 5/mm.
Stipe short, 2 × 0.5 mm. Odour nil. Dictyophanes sp.?
— There is no control for adding an image and nothing under “How to use”, but I am hoping for the best.

…is what I tried to get, I rescanned the old slide in hi precision. The detail is the poroid hymenium that Danny wanted to look at. Some agaricoid genera have pores and/or lamellæ, Panellus is one of them with the cited species as an example. So Agaricomycetes sp. may be a good title after all.

is one possibility, and it also happens to be a synonym of Dictyopanus pusillus. Would likely have to see more hymenophore detail to say for certain.

Sorry, Dictyopanus

Thank you Danny, I misspelt the suggestion of genus. D. pusillus = Panellus pusillus is somewhat similar. Anyone know that one?

is to call it a polypore, though not necessarily in the Polyporales. Dictyophanes isn’t a genus known to MycoBank or IndexFungorum.
