this filament of tissue on excerted berries has always been quite sticky in the Anthurium i've dealt with. maybe it's that way so the berry sticks to a bird's beak....or my fingers.
I believe what you are seeing is pretty universal. The inner surface of the tepals have a strip of tissue that is capable of being ripped off and this is firmly attached to the base of the berries, allowing the berries to be nicely displayed after they emerge. I suspect that this has evolved to allow for easy dispersal by birds, surely the principal dispersal agent for Anthurium according to my observations and those of Betty Loiselle who works works with bird pollination (UMSL). I have seen species where the fruits emerge and don't hang down but I suspect that if you tugged on them slowly they might also become loosened in the same way.

One of my large birdsnest anthuriums that has not fruited before is now
giving me a beautiful mass of bright scarlet fruit. I am curious about a
phenomenon which I have seen before on other big birdsnest species, that is
that as the fruits ripen they sooner or later pop out of the matrix of the
spadix and hang on a short thread. How widespread is this through the genus?
The shape of the fruit (like a candycorn) makes it very poppable, and the
almost random ripening of the fruits dotted all over the spadix also makes
the popping more likely as the remaining fruit around any given one swell.
I don't really have questions about this, apart from wondering how
widespread it is, and also why the fruits reach maturity with no apparent
pattern and over such an extended period, but would welcome anyone's
observations or comments.
Idle thoughts for an idle day. Best wishes to everyone.
