Existing in the plasmodial and cellular varieties, for ten points, identify these protists also known as myxomecetes that resemble true fungi and which famously provide food in the game Nethack.
One group of these organisms exists as individual strands called "slugs" which aggregate by reading a chemical signal. During the life cycle of that group, one variant of which is dictyostelium, these organisms pass through a sexual phase in which a pair of haploid amoebas fuse into a zygote. Another group undergoes both mitosis and meiosis; most of those organisms spend their life cycle as diploids and contain a feeding stage called a plasmodium.
