I think it would be useful to repeat here my comment I posted under the name Phanerochaete calotricha Adolf
When Zdenĕk Pouzar published his new combination Phanerochaete sanguinea, he never mentioned that Phanerochaete calotricha & Phanerochaete sanguinea would be synonyms: Pouzar, Z. 1973. Systematické postavení kornatky krvavé-Peniophora sanguinea (Fr.) Hohn. et Litsch. Česká mykologie 27: 26. In the matter of fact, he did not mention Phanerochaete calotricha at all. We follow The ‘Corticiaceae’ of North Europe / Vol. 5: Mycoaciella –Phanerochaete by John Eriksson, Kurt Hjortstam et al. They dealt with this issue on pp. 997-999 & 1021 and concluded to keep Ph. sanguinea & Ph. calotricha separate, and made a call for further studies. Mind you, Eriksson et al. lectotypified both Phanerochaete sanguinea and Ph. calotricha and this may have solved (or muddled) this issue.
In case of homotypic synonyms (e.g., Phlebia cretacea & Cabalodontia cretacea) it really does not matter what names the MO user would use, in the heterotypic synonyms (e.g., Phanerochaete sanquinea vs. Ph. calotricha), however, you cannot lump one name with another one without the study of real collections.
