You must know that Abies acts like a deciduous tree when it comes to fungi. The other Phlebia tuberculata is as far as I know re-named to BASIDIORADULUM TUBERCULATUM now.
What do you mean with slow connection? I get this remark on my computer but I do not know why and what to do against it. I am not a PC freak I just use it.

Substrate of Phlebia livida

In Europe, Phlebia livida (Pers.) . subsp. livida is mostly on coniferous wood (with one Estonian exception), whereas Phlebia livida subsp. tuberculata N. Hallenberg & E. Larson occurs on deciduous wood, but also on Abies (e.g., in Spain and Austria). See Mycological Research 97(3): 351-354 (1993). The sample size, however, was too small to make such conclusions. Limited North American material did not fit well to any of these two groups in the isozyme analysis of Hallenberg’s & Larson’s samples (cf. Fig.1).

Have you noticed that two heterotypic homonyms were both published in 2011? There are: Phlebia tuberculata (Hallenb. & E. Larss.) Ghobad-Nejhad 2011, and
Phlebia tuberculata (Berk. & M.A. Curtis) Tura, Zmitr., Wasser & Spirin 2011. Which one has the priority? Unless you know that, the safest way is to treat these two European entities at the subspecies level, if you believe in them.

BTW, why do you consistently post several identical images in your observations? The Mushroom Observer programmers claim that you have a slow connection.(I mean, “computer connection”.) Adolf

But may I add something?

Was this collection on hardwood or conifers? Look at my observations about Phlebia tuberculata (=livida ssp. tuberculata). Phlebia livida ss.str. is confined to coniferous wood (I do not know if this concept can be applied to North America though), Phlebia tuberculata to hardwood. Besides I do not think that this crystal thing is constant. When I look at encrustations they are never ever the same. Some have so much of them that you are almost unable to discern hyphae properly some have none. Although cystidia in Phlebia are inconstant. Some collections of Phlebia livida have a fairly high amount of subsubulate cystidia, some have none as P. centrifuga.
Don’t want to teach anybody here, it is just for information and knowledge exchange.

Excellent!

Thanks for the explanation and added picture!

Why not Phlebia radiata?

The section of the fruiting body shows clearly accumulation of crystals below the hymenial layer. There are no crystals in Phlebia radiata.

Looks like Phlebia radiata

Why livida?
