Description

  • Cap : It has approximately 2–7 cm long radius. It is round becoming convex then wide or with a broad umbo, the margin hanging with slimy veil remnants. It is white or cream in color. It feels smooth and sticky or slimy.[2][3]
  • Gills : They are free, non-waxy, close, broad and white in color.[2][3]
  • Stem / Stipe : The 5–10 cm long stem tapers a bit towards the top. It is fleshy, soft and has a ring. White in color, it is also sticky and slimy.[2][3]
  • Spores : Spores are globose to broadly ellipsoid and smooth.[2][3]
  • Microscopic features : The spores measure 4.56.5 x 46 µm.[2][3]
  • Flesh : Flesh is slimy and sticky.[2][3]
  • Fruiting : These mushrooms flower in between August or July and October or November.[2][3]

Distribution and habitat

L. illinita is widely distributed in North America and often found in Europe. These can habitat singly, scattered, or in groups in woods, swamps, fields, lawns, roadsides and sand dunes.

Bioactive compounds

The skeletal formula of muurolane.

A study in 2007 discovered four new bioactive compounds from basidiomycetes, isolated from fermentations of L. illinita: Illinitone A that exhibited weak phytotoxic and moderate nematicidal activities against Caenorhabditis elegans, Illinitone B that was moderately cytotoxic, Limacellone that exhibited weak cytotoxic and phytotoxic activities and muurolane sesquiterpene 4a that was found to be inactive in the assays performed there.[4]

gollark: The alternative would be to actually engage it in combat and use a lot of Last Stand enchantments, but no.
gollark: As such, assuming I could do all the infrastructural setup, I can just set up the ritual thing very carefully, bait the chaos guardian into going near its area of effect, and then [REDACTED] it utterly.
gollark: Astral Sorcery has something which can freeze nearby mobs. It appears to work on chaos guardians.
gollark: So I don't like it, and I don't want to do the boring thing of making draconic armor and using its "literally unable to die" capabilities.
gollark: That was a rhetorical question which you were expected to answer in some way. Regardless, I will keep expositing.
