Mature merosporangia of Syncephalastrum.

You can now see the row of sporangiospores that have been produced inside each tubular merosporangium.  However, the wall of the merosporangium and the wall of the sporangiospores are so tightly pressed together that they cannot be distinguished in this photomicrograph and the sporangiospores look like they are in a chain like the conidia of Aspergillus.

Students

1.  How are the spores of Aspergillus produced?

2.  In about a second how could you tell that this was Syncephalastrum and not Aspergillus?   If you say anything about 'non-septate' you don't win the prize.
