Microbotryum violaceum

Microbotryum violaceum, also known as the anther smut fungus, was formerly known as Ustilago violacea. It is a Basidiomycete obligate parasite of many Caryophyllaceae. But it has now separated into many species due to its host specificity.

Meiosis in M. violaceum produces a tetrad of four haploid meiotic products. Pairwise intra-tetrad mating can occur between these meiotic products.[1]

Examples

M. violaceum can infect and sterilize the plant species Silene latifolia by acting like a sexually transmitted infection.

gollark: It heavdrones utterly.
gollark: The heavdrone protocol is surprisingly rich and inner-platform-effecty.
gollark: I also wrote a Python heavdrone for real computers.
gollark: Also, since PotatOS appears to have entered disuse the only SPUDNET users are a large group of inevitable heavdrones.
gollark: SPUDNET supports encoding packets as JSON or msgpack. No implementation except my test JS client uses msgpack mode.
