The very distant isolated Spanish records are both from the interior, and Brolemann named them Schizophyllum albolineatum parvum. The two sites where it was found in Spain and which were recorded by Brolemann are Pozuelo de Calatrava, which is on an extensive plateau at an altitude of about 630 m, and La Granja, Peñalara, which is at least 1180 m above sea level. This evidence suggests that Ommatoiulus parvus might be a separate species. On the other hand, Schizophyllum olivarum, described by Verhoeff from San Remo and listed as a separate species in Fauna Europaea (Enghoff & Kime 2009), seems to be a synonym of O. albolineatus (N. Akkari, pers. comm.).
