Nugget moss (Microbryum vlassovii) COSEWIC assessment and status report: chapter 4
Distribution
Global range
Microbryum vlassovii has a disjunct distribution between western North America and western Eurasia, where it is rare. Eurasian locations include Spain (Jiménez et al. 1990), the Ukraine, Armenia, and central Asia (McIntosh 1997; Zander 1999). In North America it is extremely rare, having been reported only from southern British Columbia (McIntosh 1997), and California (Zander 1999; Figure 2).
Canadian range
Microbryum vlassovii was first collected In Canada in 1980 and has been reported from two locations in south-central British Columbia (east of Kamloops and on the east side of Penticton: see Figure 4 and also McIntosh 1986). Although the Penticton population was re-located during the recent survey for the species, the Kamloops population was not.
