@mahargiani pretty sure Dacrymyces and Dacryopinax are synonymous, in which case, you're correct.

Identifying some of the gelatinous fungi from photographs can be a fun(!!) – especially if they are small or have started drying out. Christina’s half right. In the two major fungal databases - Species Fungorum (https://www.speciesfungorum.org/) and Mycobank (https://www.mycobank.org/) – you’ll still see the genera Dacrymyces and Dacryopinax kept separate. However, over the past 15 or so years a few papers have pointed out that the species in those genera need re-organising – and a paper published in 2022 moved Dacryopinax spathularia into Dacrymyces. Nevertheless, there has been no suggestion of making the genera synonyms. Indeed, a quick look at some of the molecular analyses in those papers suggests that there might be difficulties in doing so but, as the various authors point out, many of the species currently in those (and one or two other gelatinous) genera need to be studied in order to determine just what distinct genera there are. The authors of all those papers have also noted that there are no macroscopic features that correlate with the evolutionary relationships suggested by the molecular analyses. That’s not too surprising, given the very limited variation in the macroscopic form of the various gelatinous fungi.

Heino. Thank you for the explanation

@Heino1 a very interesting explanation! I've had the genera used synonymously on iNaturalist and in two papers on Google scholar, but as always in the wonderful world of fungi, the simple explanation is not always the correct one! I appreciate your information, many thanks.
