I am surprized about these spores. In my understanding they cannot have a septum because large ol drops are seen just were the "septum" is.

Did you mount your fungus also in water?

Hi Susana,

very interesting, I guess this belongs to Amphisphaerella. I think it should be compared with A. amphisphaerioides, which has no septum, but 3 aequitorial germ pores and a spore size similar to your one. A. deceptiva comes also close, with somewhat bigger spores but a refractive, J+ apical ring.

I would like to study your specimen, is it possible that you send a sample of it?

regards,
björn

Hello

I did not know the Amphisphaerella genre, which I now see has characteristic equatorial pores.
I think it could be Amphisphaerella xylostei, because I feel that the substrate can be Lonicera since in the same grew a species apotecioide that I think is Trichopezizella barbata which is also typical of Lonicera, so I've read.

I can't see the spores for this species. But, you think that it is Trichopezizella barbata? (I send a photo).

Photos of the spores are made in water, I send more photo in water for see the apical ascas and paraphisis

Björn, there is little sample, but I will try to send enough for you to study.

Are you information to genre Amphisphaerella?

Regards,

Susana

Hello,
I'm not the expert, but I see A. xylostei too and as well Trichopezizella barbata.
The equatorial germ pores from the spores of A. x. I see not all the time (the  collage is not the best).
I'm interested on informations  about this genus too.
Greetings Peter.

OK when it is Lonicera, than its clearly A. xylostei. You did not mention T. barbata and I thought you have excluded A. xylostei already (which is the most common species of this genus).

You do not need to send the material, but if you want that I take a look on it, you always can ;)

I would be interested in the first one, because I do not have this and it seems as if the older papers from Svensk Bot. Tidskr. aren't available online.

Gracias Björn.

Is possible you send me article:
Wang, Aptroot & Hyde (2004). Revision of the Ascomycete genus Amphisphaeria. Fungal Diversity Research Series 13.

Does anyone available in pdf this other article:

Thanks, regards

Hallo Björn,
danke für die Literaturstellen.
Herzliche Grüße.
Peter Püwert.

Hi Björn,

I can send you a scan of Eriksson at some point during the next week (assuming no one's faster).

If anyone has one of the following publications I too would be grateful to receive them:

Vassiljeva (1998). Nizshie Rasteniya, Griby i Mokhoobraznye Dalnego Vostoka Rossii, Griby. Tom 4. Pirenomitsety i Lokuloaskomitsety (Sankt-Peterburg)

Hi to all,
there are variations in reaction to iodine among collections on Lonicera and ascospores are so variable in shape and dimensions that it is difficult to know whether one or two or more species are involved.
I attach the Eriksson's paper.
Wang et al is a book!
