Caeruleum is a genus of lichen-forming fungi in the family Acarosporaceae. Two species are currently recognized, C. heppii and C. immersum. Caeruleum is generally similar to the related genus Acarospora . [1] [2]
The generic name, "Caeruleum", refers to the blue color stain of the tholus after treatment with Lugol's iodine. [1]
The genus Caeruleum was described in 2012 by Linda in Arcadia and Kerry Knudsen, with the type species Caeruleum heppii ("Hepp's cracked lichen"). [3] C. heppii had previously been described as a species of both Acarospora and Myriospora . An additional combination was also erected as Caeruleum immersum . C. immersum has also been assigned as a species of Acarospora and Myriospora in the past. Arcadia & Knudsen (2012) noted that future research may indicate that C. immersum represents a synonym of C. heppii. [1]
Caeruleum is one of eleven genera within the Acarosporaceae family of fungi. [4]
