Taxonomic notes

= Lepiota solidipes Peck 1898.

Limacella solidipes (Peck) H.V. Sm., Papers of the Michigan Academy of Sciences 30: 142 (1945).

Even though they are identified as Limacella solidipes, some specimens reported from western North America (California, Oregon, Washington, Alaska) are probably from a different species (Tulloss, personal communication). These specimens are ignored from this assessment.


Why suggested for a Global Red List Assessment?

Even though Limacella solidipes is relatively easy to recognize, the species has been reported from only 5 sites since its description in 1898 by Peck. Its apparent restriction to wetlands suggests declining populations.


Geographic range

Limacella solidipes has been found in the United States in New York (Albany Co.; Morgan 1907), Minnesota (Pine Hollow; mycoportal.org) and North Carolina (Orange Co.; mycoportal.org). It has also been reported from Canada in Quebec province (Rimouski-Neigette and La Mitis regions; Després 2007, GBIF 2014, mycoquebec.org).


Population and Trends

Limacella solidipes has been reported from 5 sites in northeastern North America. The species has been last seen in 2007 in Quebec province, Canada. Beside the specimens from Quebec province, no observation has been reported since 1927. More information on Limacella solidipes population size and distribution is necessary to confidently evaluate a trend or a total number of mature individuals.

Descriptions from different sources are slightly inconsistent. We think this species might have been forgotten by mycologists and/or misidentified for a number of years. Limacella solidipes would then be more common than it is suggested by the data currently available.

USA: 1 site in NY (prior to 1907), 1 site in MN (1926), 2 sites in NC (1920//1927; about 1 km from each other). See Morgan 1907, mycoportal.org, Smith 1937.
Canada: 2 sites in Quebec province (2004//2007). See Després 2007 and gbif.org.

Limacella solidipes is a large mushroom and according to Kuo’s key of Limacella in North America (mushroomexpert.com) it is easily identified. However, Limacellas are not well known by amateur mycologists and can be mistaken for white Amanitas. Also, Limacella solidipes descriptions from different sources are slightly inconsistent. Therefore, it is expected that the species has been rarely overlooked, but that it was often misidentified when found.

Population Trend: Uncertain


Habitat and Ecology

Limacella solidipes is a saprotrophic fungus species that grows in summer and fall on the ground of deciduous or mixed forests (mycoquebec.org). It grows in wet, damp or swampy areas (Morgan 1907). The species has also been reported on humus under alder (Alnus) on swampy grounds (Tulloss, amanitaceae.org).

Temperate ForestBogs, Marshes, Swamps, Fens, Peatlands [generally over 8 ha]

Threats

Limacella solidipes is restricted to swampy/wet areas, and wetlands are often negatively impacted by human population growth and urban sprawl in North America (USDA 1995). Thus, this species might be threatened by habitat loss or might have disappeared from certain known/unknown sites because of habitat loss.

Residential & commercial development

Conservation Actions

There is no indication that some Limacella solidipes populations are located in protected areas. No conservation action is currently taken to protect this species. Sites where L. solidipes is currently known to grow should be protected.

Site/area protection

Research needed

Within-range habitat should be inventoried to better define Limacella solidipes populations size, distribution and trends. The inventory of sites where the species was seen decades ago should be prioritized.

The type specimen should be studied in order to clarify its description. Specimens recently collected in Quebec province (Canada) should be compared to the type specimen.
