Using the same sources as listed in Observation (5240)
One more good source that I use is:
Fungi Non Delineati: Osservazioni sul genere Melanoleuca by Fontenia, Gottardi and Para
The septate cystidia is quite distinct — the overall stature and other micro and macro features also suggestthat id.
Having said that, it needs to be pointed out that the available literature on Melanoleuca has huge gaps and glaring contradictions on most species and thus needs a critical rewrite. Yet, luckily on this particular species there seems to be good agreement, including the way it looks.
