Aspergillus

Post by Waxcap » Thu Apr 07, 2016 9:45 pm

I had a look at some mouldy bread under the microscope for the first time today. I think I have Aspergillus niger and some Penicillium.

The Aspergillus condiophore had long hyaline stems of over 1mm long and around 12 microns wide terminating in an inflated vesicle of 40 - 60 microns. The phialides were borne on brown metulae and the conidia were 3 -5 microns with a wrinkled, slightly warty, surface (when observed under 100X oil). A lot of references I could find had Aspergillus niger conidia as echinulate but this paper - http://www.scielo.br/pdf/bjm/v42n2/44.pdf shows wrinkled spores and echinulate for Aspergillus niger agg.

I did find out that Aspergillus is an anamorph belonging to the Ascomycota although there is no known teleomorph for Aspergillus niger.
