Mutated zygomite

Zygomites, called Mutated Zygomites before the Zanaris graphics update, are monsters that require level 57 Slayer to kill. They resemble giant mushrooms, and are only found in Zanaris, near the Cosmic altar (level 86), or near the furnace (level 74). To kill one, players will first need to Pick Fungi, whereupon it will turn into a Zygomite, and then reduce it to 10 or 20 life points, when players then can then use fungicide spray on it, which is available from any slayer master. The fungicide spray must be reloaded every ten kills, and the reloads can be bought from the slayer master at the same time. Players cannot sell the spray or reloads back to the slayer master afterward, so only buy what is needed. Zygomites are usually only killed as slayer assignments, but some players may kill them for their fairly common drops of Strawberry seeds.

Zygomites can be occasionally assigned as an optional Slayer Challenge by Chaelder. If you accept the challenge, she will tell you to use an experimental spray on them for tests, and you must bring back the results to her when you're finished. She will reward you with 10,000 Slayer experience and 25 Slayer Points.

Strengths and weaknesses
Zygomites mostly use magical melee attacks which consist of a headbutt that does up to 88 life points, but they occasionally use more powerful magical ranged attacks by shooting spores, with a max hit of around 140. Wearing dragonhide armour while fighting them seems to negate the damage somewhat. If praying against their attacks, Protect from Missiles or Deflect Missiles is recommended, as their ranged attacks are stronger and more accurate than their melee attacks.

When its remaining life points are around 10 to 20, use the fungicide spray on it in order to destroy it. If life points are not low enough and a player uses the fungicide spray, the zygomite will not be killed but one use of the fungicide spray will be expended.

Trivia

 * The name Zygomite is probably based on the class of fungus Zygomycota, though these fungi do not produce mushrooms.
 * If players try and attack something else while you are still in combat, it will read "There's a rather large mushroom monster trying to attack you at the moment. Maybe you should deal with it first."
 * If a frog or other Zanaris event happens during battle, the Zygomite will keep attacking you with a "thump" sound (melee attack) without any hitsplats, but will still be doing damage while you can't attack it until the event leaves.
 * Strangely, Zanaris events do not occur when fighting the level 86 Zygomites near the Cosmic Altar.
 * Once a Zygomite's life points reach zero (before fungicide is used to kill it), its melee attack will no longer inflict damage. However, the stronger ranged attack can still cause damage.
 * With the release of Fairy Tale III - Battle at Orks Rift a glitch occurred where the health bar and hit splats for a Zygomite appeared much higher in the air than they should do, and a player couldn't see how much damage they dealt or how much health a Zygomite had left unless they changed to a high view.
