Assessment in GFRLI is under the name Mycolevis siccigleba: https://redlist.info/iucn/species_view/334684
Mycolevis sicciglebus is a hypogeous fungus found mostly in western North America. Its last confirmed observation was in 2004, but observations are likely limited by the inconspicuous nature of the fruitbodies. Considering its low detectability, wide area of distribution and range of hosts, population size is projected to be above 120000 mature individuals, with no evidence of population decline. The species is therefore assessed as Least Concern (LC).
M. sicciglebus is the type species of the monotypic genus Mycolevis. It was originally described as M. siccigleba and part of the Cribbeaceae family based on morphological characteristics (Smith, 1965) but has since been placed in Albatrellaceae using molecular data (Albee-Scott, 2007).
Widely distributed in western North America, mostly in the United States of America, but has also been recorded once in Canada and in Mexico (GBIF.org, 2023; MyCoPortal, 2023).
M. sicciglebus is known from at least 24 sites, recorded between 1964 and 2004 (GBIF.org, 2023; MyCoPortal, 2023). Considering this is a very inconspicuous species with various potential hosts, a large area of appropriate habitat and distribution, the total number of sites is estimated to be higher (at least 12000). Considering 10 mature individuals per site, following guidelines by Dahlberg and Mueller (2011), population size estimated at 120000 to 240000 mature individuals. More recent observations of this species were made in Oregon (USA) in 2022 in the iNaturalist platform, but are so far unconfirmed (Hilary Dawson 2022a,b; Heather Dawson, 2022).
Population Trend: Uncertain
M. sicciglebus is a terrestrial species, hypogeous under conifers and possibly ectomycorrhizal with Abies and Picea spp. (e.g. Abies lasiocarpa and Picea engelmannii). Found mostly in montane or subalpine coniferous forests, though not exclusively with at least one record from lowland costal site in California. Fructification occurs between May and November. (Fogel, 1976)
No major threats have identified for this species.
No specific conservation measures are needed.
More research into host preference is recommended.
