I have an interesting and colourful mould, possibly an air contaminant or from debris of plants which I was studying.
It forms a mustard-yellow colony with a broad white border and a darker brownish centre. There are also light greyish-green flocks at the centre. I don't know if I have two fungal organisms intermixed, but two other colonies on other plates formed this pattern.
The reproductive structures are very interesting and there are two types. There are typical aspergillus heads, with a small, slightly swollen vessicle and one series (I think) short phialides. These produce medium-long chains of spinulose, almond to ovate-shaped spores, ca. 5-6 um long. These seem to form the green component of the mould.
Then there are yellow to mustard-brown masses 50-150 um, spherical capsules. The wall (or entirely?) of these capsules seems to be made of 5-6(-8) cellular clumps of cells (sometimes forming a flower pattern or a lobed cloud). I am not sure if this globular body is a 'capsule' or a tight aggregate of these clumps.
What do this story and morphology indicate here please?
Are there Aspergillus species which have two forms of reproduction? Or I have a cultured colony of mixed species. The uniformity of the colonies tells me its one species.
And aahh - there are also coiled structures !!!
