Observation 279138: Ascomycota Caval.-Sm.

Parasite on Ochrolechia. Having spent much more time than should have on this I’m hoping someone (Jason?) might recognize it.

I agree that you are getting to a quite sophisticated level with your microscopy. These photos are beautiful. It is just beginning to dawn on me how much patience this takes. I would love to know more about your techniques. I understand you simply ‘work’ with what you have. But you are developing distinct talents.

Hi Richard and J-Dar,

I think that you are exaggerating a bit about the quality and clearness of my photos from microscopy at bigger magnification. In fact, my equipment is very modest and I have no background in microscopy other than pratice. In my past observations of these kind of fungi, my aim was to see and document the conidiophores, which together with the spores are of taxionomic value. I don’t feel that I was very successful in that respect. Anyway, I appreciatted your kind words.

I agree, Zaca gets great results at 1000x

I have a nice quality scope and still don’t get that clarity, so there must be more to technique! I’ve been toying with trying to get the spores and asci all within one plane of focus by drawing out as much fluid as possible. A work in progress.

thanks for information; question on microscope

Thanks for suggesting Lichenodipilis and Minutoexcipula. On this one I don’t feel confident yet to go with any genus.

Your high magnification photos of spores etc. are superb. Do you have any suggestions on technique or equipment?

Resembles …

Lichenodiplis or Minutoexcipula, which are difficult (for me) to differentiate from each other.
