Helvella compressa, also known as the compressed elfin saddle, is a species of ascomycete "sac fungus" related to the Peziza cups.
Description
[edit]The distinctive fruiting body looks roughly like a fortune cookie on a stick. The brownish cap is up to 5 centimetres (2 in) in diameter. The pale stalk is up to 10 cm long and 1.2 cm thick.[2]
Similar species
[edit]The species can only be confused with Helvella albella, which is rarer, and has a darker brown cap and a smooth underside (rather than H. compressa's "faintly" fuzzy underside) and H. elastica, which is smaller, with "rounder lobes".[3] H. compressa can be distinguished from H. atra by its coloration.[2]
Helvella compressa is genetically closely related to H. stevensii, H. corbierei,[4]: 114 and H. levis (synonym of Helvella latispora).[4]: 149 H. levis is more common in Europe and the Danish call it Bredsporet foldhat ("wide-brimmed hat").[5][6] Helvella stevensii is smaller and paler than H. compressa.[2]
Distribution
[edit]Helvella compressa is endemic to North America west of the Rocky Mountains.[5]: 49 According to David Arora, H. compressa "seems to be the most common" of the non-fluted Helvellas found in California.[2] Helvella compressa is possibly also present in China and Tibet.[4]: 148
