What is an individual filament of a fungus, with an elongated mass of cytoplasm called?

Answer 1

Hyphae grow together to form a network of fibers called a mycelium mat. Also, individual hypha entwine and thicken to produce what is called 'primordia'. These 'primordia' are what some people refer to as "pinheads" because of the resemblance to a pin with a large pinhead. Primordia is the interim name in between the mycelium and fruiting body stage.

You could always ask the people over at http://www.mycowiki.org/ they have a forum and have been good with any question i've asked them through emails.

Answer 2

Hyphaea are the individual filaments and together hyphaea form a mycelium.
