Silva & Guzmán Deconica neorhombispora is a species of agaric fungus in the family Strophariaceae.

[2][3] It was originally described from specimens found near San Bartolomé Ayautla, Oaxaca, Mexico as Naematoloma rhombisporum, then transferred to Hypholoma rhombispora.

After this, it was transferred to Psilocybe neorhombispora because the name "Psilocybe rhombispora" was already occupied, but this species is now a synonym of Deconica phyllogena.

Psilocybe subbrunneocystidiata was originally named as a new species of Psilocybe from Itapuã State Park in Rio Grande do Sul, Brazil.

[2] Psilocybe subbrunneocystidiata was found to be a synonym of Deconica neorhombispora.
