Looks like a juvenile leaf form of pinnatifidum. The red spots are really pores on the petiole and exude sap which will grow a sooty mold. Not a sign of disease just a fungus enjoying a free meal of sugary sap. I’m not sure about the gold flecks. Sometimes Phillies get attacked by teeny tiny tumid mites while the leaves are tightly packed in the bud. The point where their microscopic mouth parts pierce the leaf in bud become tiny necrotic dead spot when leaves unfurl and harden off. These appear as brown or tan spots on upper leaf. Systemic miticide should solve the spots problem. It does appear to be a seasonal problem more pronounced during periods of declining temperatures and rising humidity.
Having grown a few of these P. pinnatifidum from tissue cultures sometimes they do sport out and produce plants which over sucker producing multiple plantlets with juvenile leaves in the pot instead of having a strong apical dominance producing a single strong mature plant which will sucker out later on.

Subject: [Aroid-l] Two more plants!!! One for Taylor
Just got back from a brief shopping endeavor and came home with supposedly a Philo. pinnatifidium (Please confirm.) (The Philo has small red blotches on the petioles and the lower leaves actually have a VERY FAINT dusting of gold speckles, not on the upper leaves.
The second is for Taylor - Is this Alworthia Black Gem? Or another "thing" ?
