Cryptococcomyces juniperi (P. Karst.) Lan Zhuo & C. L. Hou comb. nov. Coccomyces juniperi P. Karst., Bidr. Känn. Finl. Nat. Folk 19: 254. 1871. Basionym. = Colpoma juniperi (P. Karst.) Dennis, Kew Bull. [12] (3): 401. 1958. Type. Finland, on bark of Juniperus communis L. (Cupressaceae), Fennia et Lapponia, collected throughout the year (exact date unknown), P. Karsten (A holotype needs to be designated). Notes. Phylogenetically, a non-type sequence of Cry. juniperi clusters with other species of Cryptococcomyces, which also occur on Juniperus spp. Dennis (1958) transferred Coccomyces juniperi to the genus Colpoma based on its slender paraphyses with spirally coiled tips (Dennis 1958). However, species of the genus Colpoma usually have elongated and curved ascomata with a single longitudinal opening slit, whereas Cryptococcomyces juniperi has subglobose ascomata with 3 to 6 triangular flaps (Dennis 1958; Johnston 1991; Lin et al. 2012). Therefore, based on their phylogenetic position, morphological similarities, and host relationship, Cry. juniperi is proposed to belong to the genus Cryptococcomyces.
