cloud flying regulations

There has been a few articles in SOARING on this lately, and perhaps a
thread or two. Some have quoted the USA FAR's about flying gliders in
clouds, or to be exact: in conditions less than VMC, but I haven't been
able to locate the actual regs. Do any of you have the specific reg
numbers for the following quotes from Tom Reesor's letter in the August
SOARING magazine?

1. Current FARs require the pilot to be instrument rated in
single-engine airplanes and also have a glider rating ... to fly a
glider in clouds.

2. Gliders flying on instruments are required to have a full gyro
panel.

Thanks in advance, and safe soaring!
