Hi all:
=20
A thank you to Jim Wolford for obtaining an answer to my fungi. For those =
interested in such, it cannot be identified exactly other than under a micr=
oscope, but there are two possibilities as below. This is the reponse back=
to both Jim and I.

It is both a fungus and a mold, as all molds are fungi. The odd colonial sh=
apes are probably determined by what it is growing on, ie the points at whi=
ch individual pickles touch or nearly touch the surface. On an appropriate =
homogeneous medium the colonies would be circular. The blue-green color is =
caused by carotenoid and related pigments in the mature spores (there to pr=
otect spore DNA from visible and UV light-mediated damage). This blue-green=
color is very common in ascomycete fungal spores. The most likely genera a=
re Aspergillus and Penicillium. A quick look through a microscope at 50-100=
x will tell you, as Aspergillus and Penicillium have distinct and distinctl=
y different spore arrangements on the mature sporophore.
