Craterellus boyacensis Sing. spec. nov. in SINGER R. & J. H. MORELLO (1960). Ectotrophic forest tree mycorrhizae and forest communities. Ecology 41 (3): 549—551.
This is a rare species that has so far been collected only in three New World countries and that forms
associations with oak trees. Oaks are currently classified as a VU species according to the colombian national red list. 60% of this specie’s habitat is being lost at an important rate (Rangel, 2005), making it a good candidate for a global Red List Assessement.
Because of loss of its habitat and the personal observed declining population of this species in Colombia, it may be VU A2c but because its geographical range is quite wide we considered is as NT
Species described in Colombia initially by Singer. Distribution extends to Costa Rica and Guatemala. In Guatemala only one specimen has been found in Cerro Miramundo, Jalapa, at 2800 m, in mixed forest with conifers and broad leaves trees (Flores et al 2008). In Colombia and Costa Rica reports from diferent Quercus forest exist
Since Craterellus boyacensis forms ectomycorrhizal associations with oak trees, its population is most likely declining due that oaks, with VU status according to the national red list, is being lost at an important rate. Q. humboldtii is endemic to Andean highlands, and grows from 1000 to 3200 m elevation. Montane forests in Colombia are also very threatened due to deforestation and mining, so it would be reasonable to
believe that C. boyacensis populations are declining in this country as well. We have observed, through samplings during 28 years, that the populations of Craterellus boyacensis have been declining in Colombian forests.
Population Trend: Uncertain
On the ground in oak woods (Quercus humboldtii) in groups, fluffing during a period of little precipitation (Singer, 1963). Craterellus boyacensis forms ectomycorrhizal associations with oak trees in Colombia and Costa Rica. Other specimens have been found in Guatemala in mixed forests, at around 2800 m elevation.
Rapid loss and fragmentation of habitat due to mining and farming activities.
No conservation actions are currently in place for this species in Colombia. Protection of its habitat is needed.
Sampling is neccesary to know the biology and ecology of Craterellus boyacensis.
