ACS ABV440: the numbered Albino Bluey Vuitton selection
ABV440 reads like a part number, and that is roughly what it is: a numbered selection out of the albino form of Bluey Vuitton, worked by A.C.S and carried by Mushrealm. Here is what each part of the name means.
01What ACS ABV440 is
ABV is the library's established shorthand for Albino Bluey Vuitton, the unpigmented form of the Bluey Vuitton line. 440 is the selection number, the convention breeders use to tell one worked phenotype from another when several come out of the same population. ACS is the group that did the isolation. Put together: the A.C.S selection numbered 440, taken from Albino Bluey Vuitton.
02Lineage and history
Bluey Vuitton is the pigmented parent, and its history is documented further back than most. The library's own record puts its start around 2014 and credits the original work to the breeder Silly Cybin, describing it as a hybrid of Panama x Melmac Penis Envy. That parentage puts a Penis Envy line on one side, which is why so much of the family behaves the way it does.
Albino Bluey Vuitton is the albino isolate taken from it. From there, A.C.S worked the line further and numbered their selections, of which 440 is the one the library carries. Alongside it the library also lists the broader Albino Bluey Vuitton (ACS iso), so you can compare the numbered selection against the line it came out of.

A 440 is not better than a 156; it is a different phenotype chosen out of the same pool.
03Under the microscope
ABV440 is an albino line, so expect the same subellipsoid, thick-walled cubensis spore with a germ pore, carrying almost no pigment. A print from it runs pale grey rather than purple-brown, which is the fastest test of whether a line described as albino really is albino rather than leucistic. Our guide to albino, leucistic and true albino covers that distinction.
Because the Penis Envy side of the family prints thinly, expect a sparse drop. Lower the light, close the diaphragm partway, and the walls resolve cleanly. Next to the pigmented Bluey Vuitton on an adjacent slide, ABV440 is the clearest demonstration in this chapter of what removing pigment does to a spore.

Questions people ask
What does ABV440 mean?
ABV is Albino Bluey Vuitton; 440 is the A.C.S selection number for one worked phenotype out of that line.
Is ABV440 the same as Albino Bluey Vuitton?
Same lineage, narrower selection. ABV440 is one numbered isolate; the Albino Bluey Vuitton card is the broader A.C.S line.
Can I buy this strain legally in the UK?
Spores contain no controlled substance and are sold for microscopy, taxonomy and research. Germinating them is an offence in the UK, which is why every specimen here is supplied strictly for microscopy. See our Legal Use Policy. This is not legal advice.
