Neither light yellow, nor brownish orange, but somewhere inbetween. Too young or too old?

these don’t strike me as being “light yellow,” as in P. panelloides. There is, however, P. amarescens, described from Brazil:

Pleurocybella amarescens (Singer) Raithelh., described from Brazil, differs in forming larger (26–40 mm diam), brownish orange pilei, pale brownish orange lamellae, has a lateral stipe and smaller basidiospores (5–5.5 3 3.8–4 mm; Singer 1973b).

though whether the attachment in yours qualifies as a lateral stipe, I’m not sure.

This is assuming, of course, that this is indeed a Pleurocybella
