I did. did you receive my reply or hear back from Roo?

And perhaps more important for this group( if I understand correctly), germ slit length. I did not yet attempt to section the darker, misshapen portions of this collection; maybe I can still find some sexual structures.

There are a lot of records of longiana in our database, as well as specimens labeled as such in the herbarium. Did you relieve the email I sent you on the topic of Xylaria?

Some quality time with a xylariologist has informed me that species level identifications are largely dependent on ascoscpore and ascus tip size and morphology. therefore an ID is likely out of reach with this material until or unless more mature FBs are collected.

are 8.3 X 3.5. No ascospores observed.

Never heard the term, thanks! There are beech, gum and sycamore in that park. I honestly don’t know what the substrate was here and I think that will prohibit this observation from ever getting to species. I’ll scope it someday.

though I think it’s actually ‘beechmast’ for both singular and plural (see: http://en.wikipedia.org/wiki/Beech)

Microscopy may help. The conidial phase, if I’m not mistaken, always precedes the sexual phase. If these were collected at the same stage of development as is shown in the photo, they may be too immature to observe ascospores, but it never hurts to check.

Danny means beech nuts, I think.

Litter may have been present. I’m not sure what you mean by a mast? Xylaria is definitely the appropriate name for this obs. I dried these… I wonder if microscopy on this specimen alone will get me to species. If I understand correctly, most Xylaria have different microscopic features across their different sexual states?

is restricted to beech masts.
