Trying to identify a white mould growing on the surface of glass. Colonies slow-growing, white (magnolia) forming small humps with clefts on PDA, possibly xerophilic (growth temp at 22C = 8mm colonies).
Under the microcope I saw realtively thick curved mycelia but loose and not interwoven, irregular/flexuose, septate, losely branching, 7-9 um thick, rather stout and robust. Conidiphore not numerous, thick, solitary or few branched (x3) very long, swollen at the top, penicillate conidiogenesis apparatus with few(-several) clustered phiaides (?), irregular in length like many fingers. The condiospores seems to be rectangular and of various sizes up to 12um.
I think it is an Aspergillus, but not one I am familiar with.
Aspergillus vitricola and A. tonophilus has been previously isolated from glass, but I don't think they are my specimen. However are there Aspergillus with rectangular spores, shortly catanate? ?
