My wife Ean Ean was just about to throw away some moldy bagels this morning when I shouted – “No!” – perfect for my microscope – pictures below. At low power (4x objective) the scrapings of mold from the bagel look like what you would expect – green bits of scraped off fluffy stuff. But when the magnification is increased a sea of spores is revealed – in fact there is hardly anything else except spores!! (Occasional strands of fungal stems but these are rare to find in the sample). I did not realise that fungi produced just so many spores. Yipes!

Green-fungus-from-bagel-phase-contrast-Ph1-40x-objective-140517.bmp (below) – the next two images both show that my illuminator does not produce enough light for high magnification phase contrast/dark field microscopy. I tried a new bulb together (60W tungsten filament) and it made little difference. The manual for the microscope talks about using an attachment which allows two illuminators to be used at once – however when I looked on ebay these are horrendously priced second hand ($300). Not viable! An alternative solution is required…….
