Do a thorough testing of your tank including checking salinity and temperature. If you're using a hydrometer be sure to calibrate it, to double check as hydrometers are often out by 0.002 or more, which doesn't sound like much, but it sure can be!

do you dose lots of calcium?
I find they dislike that and high alk also a low nutrient tank could make them unhappy and lastly too much light on certain mushrooms are fatal even ricordea. I have melted a few in my day however if you had it for a year and it was fine maybe you dosed something?

i started dosing calcium and alk because im switching to sps and slowly starting to phase out the softies. i heard its much easier to raise sps specifically rather than a mix. so it could be the dosing doing it.

I've had the same thing happen recently with some of my Rics which were under 250W MH. One colony I had for 4 years and then suddenly they all turned white and disappeared. Around the time it started happening I dont recall doing anything different to my tank. If anything things were improving because I was bringing my nitrate down from ~10ppm to <1ppm with a few improvements to my filtration (larger skimmer and filter socks).
Salinity 1.025 (refractometer) Temp 27ºC pH 7.8-8.1 Ca 400 Alk 10 Mg 1300 Nitrate <1 Phosphate .1 (was higher back then and has always been higher until now)
