Usually, it's very hard to identify fungi based on its morphology. It is easy if i have specimen of fungi culture to refer to, instead of referring to fungi plate photos. If there any, i would to try preserve microfungi on plate for future references.
We usually make hi-resolution photos of the colonies on Petri dish and its reverse. You may also prepare permanent preparations of mycelium on glasses (embedded to canadian balsam for example) to examine microscopic details long time after the cultivation time ended.
Discomycetous species (where some macro features in fruit bodies are valuable) are usually stored in a paper envelopes
We have collection of microfungi photos in our database. Here the examples of plate photos (surface and reverse) we have. But most of the time I still confusing with the morphology because some of the genus looks similar. Unless for the fungi strains that already have microscopic ID, so it easy to confirm the genus.
If you store them as "classical" herbarium microscopic morphological details will be lost.
Fix some mycelium from every Petri pkates and make permanent preparations on subject glasses as I suggested above. Even in glycerol you may store mycelium for microscopy quite long. In media like canadian balsam or similar mycelium may be safe for years.
Ooo...ok. Thanks a lot Maria V. Kozlova. Really appreciate for your knowledge and information.
You can only have them photographed. However, for macro fungi like Mushrooms, you may get the spore print on blotting paper and dry them.
We usually attach a transparent tape to the culture, dettach it again, and tape it on a clean deck glass. You kan put that tape under the microscope in the future whenever you want, With a drop of Cotton blue. The tape will then be the cover slide.
Maria Paz Nunez, I want to know wether the method you've mentioned suitable for non-sporulating fungi? I think i've tried the method before but the problem with non-sporulate fungi compare to sporulate fungi like aspergillus...
