Item #: SCP-XXXX

Object Class: Euclid

Special Containment Procedures: Mobile Task Force Iota-16 ("Spin Doctors") is to monitor hospital admissions records for patients with symptoms resembling those of SCP-XXXX. After confirmation of infection can be established, members of MTF Iota-6 should extract the host(s) of SCP-XXXX and relocate them to the nearest Foundation facility equipped to contain Euclid-class anomalies of a biologically infectious nature. All individuals that came into contact with hosts of SCP-XXXX must be monitored for a minimum of 30 days after the extraction of the initial host, in order to establish that SCP-XXXX has not been transmitted to additional hosts.

Hosts of SCP-XXXX are to be contained in standard humanoid containment chambers. If collection of a host's instance of SCP-XXXX-1 can be achieved and no further symptoms of SCP-XXXX are observed within 30 days, the former host may be permitted to leave containment after receiving appropriate amnestic treatment (see Document XXXX-AT).

Collected instances of SCP-XXXX-1 are to be stored in small humanoid containment chambers. Twice daily, each collected instance of SCP-XXXX is to be fed 1 gram of animal-based protein powder. Personnel assigned to this task are to report any changes in SCP-XXXX-1 appearance or behavior to SCP-XXXX's onsite containment deputy director.

Description: SCP-XXXX is a species of dermatophytic fungus bearing genetic similarities to members of genus Trichophyton1, though distinct from any known fungus species. Due to its presumed relation to these fungi, SCP-XXXX is believed to spread in much the same way, transmitting to human hosts in moist communal areas where shoes are worn infrequently; however, research in this area is still ongoing. Direct transmission through contact with instances of SCP-XXXX-1 is also possible, though this is presumed to be uncommon.

Initial symptoms of SCP-XXXX bear a close resemblance to onychomycosis2, with the thickening and discoloration of the toenails on the infected foot. These symptoms progress more rapidly on the host's big toe than on the other affected toes, with the toenail becoming abnormally hard and brittle within 72 hours of infection. Simultaneously, the cuticle of the big toe becomes abnormally soft and flexible, and the nail plate begins to detach from the nail bed, usually detaching completely after 90 to 120 hours post-infection.

Once complete detachment of the nail from the nail bed has taken place, an opening will appear on the host's nail bed. The dimensions of this opening are the same as those of the nail bed of the host. The opening leads to an extradimensional space approximately 265 cm3 in volume, inhabited by an instance of SCP-XXXX-1.

SCP-XXXX-1 are masses of SCP-XXXX fungus approximately 20 cm in diameter, though dimensions are highly variable among multiple instances. Each instance is capable of extruding limbs from its mass to form a roughly humanoid stance, though the body remains a shapeless and featureless mass. Instances of SCP-XXXX-1 are sentient and capable of speech, though their mechanism for doing so is unknown. All known instances of SCP-XXXX-1 thus far speak only English in a strong Upper Midwestern dialect, regardless of their hosts' spoken languages or regions of origin.
