I reduced my vote for D. childiae, accordingly.

at least a cross section would be good to have, possibly KOH as well (for extractable pigments), though I can’t remember if that’s as important for Daldinia as it is for Hypoxylon and Annulohypoxylon. Werdnus is really the person to ask, but sample size of North American Daldinia in that paper notwithstanding, I think it’s fair to say that macroscopic species level identifications of this and other xylariaceous fungi have the strong potential to be dodgy, save for the most iconic of species, of course.

I would like to see stronger phylogenetic data with more specimens from North America. The short stipe and color led me to D. childiae, based on the info in paper you shared. Although the holotype is from France, it is said to be common in eastern North America, yet they only include two collections of D. childiae from north America in their phylogenetic study. It would not surprise me to find even greater diversity.
As I understand it, speciation can often happen before there is any definable morphological changes (so much for Bas’ three distinct traits rule). I also like the idea of the term ‘subspecies’ for some of these cryptic species, things like ‘variation’ and ‘form’ do not highlight the unique ecological and geographical niches that the term ‘subspecies’ affords, and full delination may not be appropriate for species that are very closely related and are able to breed at least partly, in culture. I know the older ITS sequences do not capture divergence in species as well as some of the newer methods. In the future I will try to include more info from the field, such as cross section, KOH reaction, etc.

Best wishes,

Herbert

with 47 recognized species, it is probably a matter of microscopy to differentiate between and among the Daldinia of the Northeastern US. See: http://www.ncbi.nlm.nih.gov/...

“The D. concentrica group comprises the type species and several related taxa that are typically distributed in mild temperate and subtropical climates of western and southern Europe; some related taxa occur in tropical Africa and in the Southern Hemisphere. They have so far not been found in the Americas and the temperate regions of Asia, despite diligent search. All previous records of “D. concentrica“ from Asia and America obviously need to be revised.” http://www.studiesinmycology.org/...

more infor for better identification. When photographing most fungi, slice them in half through the stem, including as much of the base as possible. Photograph the interior as close as possible. In Daldinia, many of the species characteristics are located in the peridium (the outer shell) and the gleba (the spore-bearing mass that looks like a puffball). In addition, identifying what species of tree the fungus was growing from can be quite helpful.
