Assessment Notes
I have selected DD since its records are old and I couldn’t find or access original articles with the descriptions of the species. Records from India and Japan may be more recent, but I can’t be sure because they seem to have been listed based on herbarium vouchers. Even so, based on distribution, inconspicuousness and the fact that it grows on dead wood, likely of different hosts, we may argue that population size is large enough and go for LC.
Note: MyCoPortal also includes one more record from New Zealand, in Auckland, Three Kings, growing under Pinus radiata that I didn’t consider in this assessment (https://www.mycoportal.org/portal/collections/individual/index.php?occid=1173390&clid=0). Ginns(1972) mentions one specimen from this same location and host that was incorrectly identified and was changed to Coniophora puteana. I have checked in MyCoPortal and collector and date of collection between these two specimens is also the same (https://www.mycoportal.org/portal/collections/individual/index.php?occid=11747156&clid=0). I assume that they were collected simultaneously but deposited in different herbariums.
Justification
Scotoderma viride is a resupinate species described for New Zealand and since reported for Himachal Pradesh in India and for Japan. This species appears to have a large distribution and is likely under sampled because of its inconspicuous fruitbodies. However, the few documented occurrences are either more than 50 years old or have no date information. Without more recent records or search attempts it is difficult to estimate current population size and determine whether this species is Least Concern or applies for a Threatened category. For this reason, the species is assessed as Data Deficient (DD).
Taxonomic notes
Only species in the Scotoderma genus, established in 1974. It was initially described as Corticium viride and later transferred to Coniophora viridis, with Thelephora viridis as its synonym. However, this was later disputed (Ginns, 1972) and T. viridis is not currently accepted as a synonym in Species Fungorum (2023). No sequence data is available for this species, and Larsson (2007) included it in a list of incertae sedis genera (familial position was not determined).
Why suggested for a Global Red List Assessment?
Geographic range
Originally described for New Zealand but has since been recorded in the North of India (Himachal Pradesh) and included in a list of corticioid fungi in Japan.
Population and Trends
S. viride is known from at least 8 sites: 4 in New Zealand, 3 in Himachal Pradesh in the north of India, and at least 1 site in Japan. (MyCoPortal, 2023; Prasher and Ashok, 2013; Maekawa, 2021) However, most New Zealand records are now more than 50 years old and it is not clear when the other collections were made. The number of observations is likely limited by the inconspicuous fruitbodies, and its large distribution could be suggestive of a larger population, but a review of herbarium specimens and new collections are needed to accurately estimate current population size.
Population Trend: Uncertain
Habitat and Ecology
Grows on dead wood, namely of Cedrus deodara (Prasher and Ashok, 2013) and under Abies forest (MyCoPortal, 2023, record BPI 348338) in Himachal Pradesh.
Threats
Unknown.
Conservation Actions
Research needed
A review of herbarium specimens available along with new search attempts are needed to help define current distribution limits, population size and habitat preferences. Sequence data and a review of the taxonomic placement of this species is also recommended.
