Item #: SCP-PL-166

Object Class: Safe

Threat Level: Blue

Special Contaiment Procedures: The subject should be cultivated on standard mushroom growing medium. The lower layers of the substrate must be enriched with the constantly supplied amount of human muscle tissue or internal organs, appropriate to the current needs. In justified cases and there is a significant risk of breeding, it is allowed to use the whole human body.



Description: SCP-PL-166 is a species of fungus resembling members of the genus Xylaria, specifically Xylaria longipes (Long-leaved humus). The main feature that distinguishes it from ordinary animals Xylari is saprotrophic feeding on dead human tissue.1 All the specimens obtained so far have been discovered in cemeteries, which is a logical consequence of the most favorable conditions for growth in the necropolises.

Like the normal representatives of Xylaria, SCP-PL-166 is not of significant size and has a similar biological structure. The elongated mycelium allows the absorption of nutrients from the carcass under the soil.

The organism is capable of bioluminescence taking place in fruiting bodies due to appropriately modified tissue. The glow produced is imperceptible during the day and noticeable after dark. The light emitted by fruiting bodies has a different color, usually not exceeding the basic colors. The intensity of the glow emitted is strictly dependent on the amount of nutrients in the carcass used and it decreases along with their depletion.

SCP-PL-166 can often be equated with light sources traditionally left at the burial site, as the glow, due to its low brightness, can be mistaken for an extinguishing, incandescent candle. The fruiting bodies with rootstocks, which are imperceptible during the day, do not differ much from the local biocenosis. The above-mentioned features are responsible for such a late recognition of the facility by the Foundation.

Addendum # 166-1: Object Properties Can Be Helpful in Forensic Broadcasting. Since the subject is able to live actively only on human tissues, its existence clearly indicates the presence of a corpse, which can be noticed and can be an invaluable help in finding them. Due to the lack of knowledge regarding the natural reproduction of SCP-PL-166 by seeding spores, using the helpful property without artificial cultivation is a matter of the future.

Addendum # 166-2: SCP-PL-166 was obtained from the parish cemetery of St. Wojciech in Mikołów. A significant amount of the mushroom was artificially planted on the newly created grave of Małgorzata ███████. The amount of light emitted aroused the interest of the cemetery caretakers. The Foundation reacted after information was leaked to the public.

The investigation led to the husband of the deceased, Zbigniew ███████. Agents in the man's home found materials indicating membership of Polish Anomalous Mushroom Association. From the obtained items, a pamphlet issued by the Association containing information about SCP-PL-166 was found and an empty chest in which, as Mr. Zbigniew testified, was a mycelium with developing rootstocks. The package was to be received at a special request, supported by the situation and the recent discovery of a rare mushroom.2

The following is a PZGA-printed brochure containing a description of SCP-PL-166:

Graveyard skylight
Lux caemeterium

Inedible mushroom [❌]

Appearance: Small club-shaped bases rise above the soil surface. The fruiting bodies that do not differ from the base are on their tips. The mycelium is very extensive and extensive.
Anomalous properties: Creates a colored glow depending on the decomposition state of the human carcass on which it feeds.
Occurrence: Cemeteries or other places of mass storage of corpses.
History of use: Discovered in 1891 by Miłosz Przybyłowski. Appreciating its aesthetic qualities, he began to cultivate it, which was condemned by the Board due to the method of collecting the remains for breeding purposes. Currently left in the wild, the few maintained and controlled cultures operate in concert with the medical facilities supplying tissue.
Recommendations: Ideal conditions for mushroom hunting are at night. The mycelium can be safely removed at the top of the soil, but it is advisable to keep the piece adjacent to the rotting tissue to leave the fungus alive.

Due to the fact that the man was a regular member of the Association, he was given a class D11 amnestics and released under the supervision of agents. Before being released, the man testified that he "wanted the light for Małgosia to shine as long as possible".
