Re : Phaeohelotium epiphyllum var. epiphyllum...?
The substrate is rather unimportant. P. epiphyllum grows on any kind of woody plant parts. Likewise P. monticola which has a more intense yellow colour and which I would more expect in your case.

Re : Phaeohelotium epiphyllum var. epiphyllum...?
Thank you Hans-Otto. According to Index Fungorum, the current name for Phaeohelotium monticola is Hymenoscyphus monticola. This pointed me in the direction of genus Hymenoscyphus, which I see includes many species, some of which grow on old leaves.

Re : Phaeohelotium epiphyllum var. epiphyllum...?
Yes, but genetic results show that P. monticola is rather distant from Hymenoscyphus and may well be separated at the genus level. See my paper on Phaeohelotium terrestre agg.
