Dear friends,I have recently found a Sordariomycete with very long ostioles and non-septated, hyaline spores with a striate surface. I thought this to be Lentomitella cirrhosa, but I am not sure because of the absence of septa. It spores meassure 14-17x4,3-5,8µm. Asci are 90-125x5-7µm, IKI -, Congo + (deliquescent), with distinct apical structure, spores uniseriate. Lots of periphyses seen in the ostiolus.
Perithecia are partly embedded into the wood surface and are 0,5-0,9 mm. Found on very wet wood (probably aquatic).
There is also a photo which shows an abnormal unispored ascus with a spore about 65x7µm.
What else is possible except Lentomitella?
thanks for help and regards,
björn

Re : Lentomitella?
Perhaps you should look towards Natantiella genus ?

Re : Lentomitella?
But Natantiella ligneola has smaller ascospores.
Sorry, I also think it could be Lentomitella tomentosa, but the width fits not well and you haven't said if your one is tomentous.
Conclusion : I don't know.

Re : Lentomitella?
Oh I am so sorry I have forgot the photo of the tomentose outer surface :(((
sorry Alain, here it is. After reading the article about Ceratostomella I have also thought it could be C. tomentosa, but I was very unsure because I did not ever heard something about this species before.

björn

Re : Lentomitella?
I read your first post again and I note you have said that ascospores are striate, aren't they ?
It's a problem because L. tomentosa has smooth ascospores. Thus the size of ascospores of Lentomitella tomentosa is : 13–16(–17) x (5–)6–7 µm.
Have you tried colouring agents or Melzer ? Sometimes, it shows septation difficult to locate.

Re : Lentomitella?
Of course, I have tried with Melzer, but there is no septation. I also thought the spores are immature and because of this without any septation. Striate ornaments were detected on several spores in H2O and especially in cotton blue, but very hard to photograph.
it seems to be a L. cirrhosa variation just without septation (?).

björn
