Family Sebacinaceae K. Wells & Oberw.

Mycologia 74: 329 (1982)

Type: Sebacina Tul. & C. Tul. 1873

These jelly fungi have transversely septate basidia similar to Auricularia. Many of these are ectomycorrhizal, others are endophytes.

Family Serendipitaceae M. Weiß, Waller, A. Zuccaro & Selosse

New Phytologist 211 (1): 22 (2016)

Type: Serendipita P. Roberts 1993

Members of Sebacinales that lack macroscopically visible fruitbodies. Signature nucleotides of internal transcribed spacer (ITS) and 28S rDNA sequences for this group are given in Oberwinkler et al. (2014).

For Sebacinaceae, there were two genera known for the Chicago Region. Both genera were polyphyletic, containing multiple groups of species that are not directly related. Some of these fungi were lumped into one broad Sebacina genus. Tremellodendron is just one of the growth forms of Sebacina, as is Tremella reticulata that was moved to Sebacina recently. Some species were split out and others shuffled between various genera. See the papers listed below. Two of these new combinations appear to have nomenclatural problems.

  1. Sebacina, S. candida, S. incrustans, S. pallida, S. sparassoidea
  2. Helvellosebacina, H. concrescens
These jelly fungi were formerly in the Auriculariales and also at one time in the Exidiaceae, Tremellales, but DNA phylogeny puts them in a basal position in the Agaricomycetes.
