This colony grew along a fallen Alder trunk in a very damp area.

I found it with Phlebia radiata, Crepidotus, Daedalopsis tricolor and Exidia nucleata.

I found a veiny plasmodium covering the wood or moss on all sides.

Other, spherical or ovoid, sporangia were hanging off the bottom on thin yellow stems.

These sporangia were speckled, but ‘matte’ where they joined to the stems.

Somemore mature of the group, were various shades of blueish grey.

In the photo below you can see where the plasmodium is consuming the corticioid fungus Phlebia radiata.

This is a common occurance in B. utricularis [1].

On Day 21, they had all turned into the mature, light bluish-grey sporangia with none of the yellow forms left.

Plasmodium was still around in some areas, forming clusters.

On Day 23, you can see the darker, more orange coloured sporocysts combined with the mature, light grey forms.

The stringy stems were still yellow.

On Day 23, I mainly saw the plasmodium and colony of mature grey forms.

On Day 26 (28th 01 2024), some more yellow sporangia were growing:
