Sphaeropsis sapinea? on cones of Pinus sylvestris
Ethan Crenson, 06-02-2017 02:41
Found this on cones of Pinus sylvestris in Brooklyn, New York.  Tiny (less than 1mm) erumpant black perithecia.  Conidia brown, ellipsoid to irregularly cylindric, occasionally 1-septate, but mostly non-septate.  30 - 40um by 12 - 14 um. Is this Sphaeropsis sapinea?

Hello Ethan

I would say, that yes this is what you have found. Occasionally you may even come across 2-septate conidia.

Re : Sphaeropsis sapinea? on cones of Pinus sylvestris
I agree with Chris, but you should know that there is a proposition for reverting this name to the older one (viz. Diplodia pinea). Additionally a new species (D. scrobiculata) was segregated from "Sphaeropsis sapinea s.l." See the attached paper to try to verify if your fungus is really "S. sapinea".

All the best!

Re : Sphaeropsis sapinea? on cones of Pinus sylvestris
Interesting, I see that D. scrobiculata was also collected from Pinus resinosum; I collected Diplodia pinea on red pine needles and cones early last summer and cultured it on a whim, I should look into what species it really is.

I also saw the odd 2-septate conidium as Chris mentioned.
