Rank ReasonsMuscinupta laevis is circumboreal in the northern hemisphere, but appears to be rare in many of the countries in which it is found. The estimated number of occurrences is 70. Logging is the primary threat to the species.
Range Extent CommentsMuscinupta laevis is found in Italy, Germany, Austria, Czech Republic, France, Norway, Mexico, Puerto Rico, Alaska, British Columbia, Washington, Oregon, Idaho, New York, Connecticut, New Hampshire, Vermont, and Quebec.
Occurrences CommentsEstimated number of occurrences is 35-40. The ISMS database contains 3 records, all three of which are located in Washington. The University of British Columbia Herbarium (Fungal) database contains 8 records. The University of Michigan Fungal Bioinformatics Project database contains 3 records, all located in Washington state. It is uncertain whether all three of these records is identical to the ISMS records, but because of their protection status, it is assumed that at least two of these sites are the same. Other areas where this species has been noted include Ontario, Canada (2 records); northern Europe [Belgium (3 records), Great Britain (more than 25 records), Norway, Sweden, Switzerland and possibly Denmark]; and Shikoku, Japan.
Threat Impact CommentsThis species is threatened by widespread logging, road and trail construction, or other activities that destroy the mossy substrate on which this species occurs. There are about 4 occurrences in the United States in protected areas. Scope ranked as a range high-low because the species is listed elsewhere and potentially at risk. Based on a 40 year logging rotation assessment we have used as a guide the rating would come out as a medium threat, however, the threat may be higher based on the last assessment.
