Phaeohelotium on Pinus cone

These pale-yellow fruitbodies were growing on core of a Pinus sylvestris cone.
I'm wondering whether this is P. epiphyllum or P. lutescens, and what is the best way to tell these species apart.
Spores:
(13.8) 14.4 - 15.9 (16.7) × (4) 4.2 - 4.6 µm
Q = (3) 3.2 - 3.7 (3.9) ; N = 15
Me = 15.3 × 4.4 µm ; Qe = 3.5
Q = (3) 3.2 - 3.7 (3.9) ; N = 15
Me = 15.3 × 4.4 µm ; Qe = 3.5

Re : Phaeohelotium on Pinus cone
P. lutescens seems to fit very well. It may also be that P. epiphyllum differs from P. lutescens in isodiametric cells on the flanks and having only prismatica towards margin.
P. lutescens grows on undecayed coniferous substrate, unlike P. epiphyllum.

Re : Phaeohelotium on Pinus cone
Thanks again. P. epiphyllum growing on Picea cones / needle debris is pretty common though, if I'm not mistaken.
