Gubbage Cone

Gubbage Cones were a race of intelligent, carnivorous fungi native to Pluvikerr. On the planet Mechanus, however, the Doctor, Ian and Barbara called them fungoids.

Circa 59,000 BC, they were the dominant empire in the galaxy. Their empire encompassed the silicon Excalbians, the feathered people of Velopssi, androids from Exo III, the Lamp People of Badafex, Ice Warriors and Ogrons, as well as Mire Beast fighting pits. (MA: The Crystal Bucephalus)

By the 23rd century, Steven Taylor's native time, the Gubbage Cones were living on the planet Mechanus, where they attacked the Doctor, his companions and the Daleks, who had just arrived in their DARDIS. They could be repelled by bright light. (DW: The Chase)

Behind the scenes
Gubbage Cones were not named in on-screen dialogue, by the credits, in the novelisation of The Chase, nor in the original script. The name can, however, be traced to the shooting script, perhaps indicating that the name originated with the special effects or design department. They are only called "fungoids" on-screen, which is why many non-fictional reference works also use that term.

Indeed, the name of "fungoid" is backed up by official documentation sent to BBC One, in which the actors who played the fungoids are instructed to be only semi-credited under the word "with", but "with" is given the parenthetical "(fungoids)", which did not appear on-screen.

Nevertheless, author Craig Hinton somehow got a copy of the shooting script, leading to his use of the term "Gubbage Cone" in his book, The Quantum Archangel, which began a short-lived renaissance for the species.

The comic story The World That Waits features fungoids on Mechanus but these creatures look entirely dissimilar. This is likely attributable to John Woods not having any references to work from to draw Gubbage Cones.
