Is it possible to get a name for this or is this some random, nameless memeber of fungi imperfecti?

Re : Black 'wool' on resin
This could be Amorphotheca resinae, a species that is able to metabolize hydrocarbons. It can sometimes be a contaminant in jet fuels. The anamorph is often reported as Cladosporium resinae.

Re : Black 'wool' on resin
Could it instead be the mononematous form of Sorocybe resinae? I think that is more likely to find on resin. The adoption of the epithet "resinae" for the kerosene fungus was based on an error (https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2104743/), though it has been reported from resin (https://doi.org/10.1002/j.1537-2197.1942.tb10247.x).

Re : Black 'wool' on resin
Thanks! In the pictures it does look quite similar. Amorphotheca, Cladosporium, Sorocybe, Hormodendrum... a confusing number of resinaes.
