The next few decades witnessed some lingering confusion as to the correct taxonomical placement of these fungi. In , Jean Boudier moved both G. Seaver proposed that both were synonymous , representing variable forms of the same species. This group includes other species of the genus Gyromitra, such as G. Description[ edit ] G.

Description of the genus The genus Gyromitra includes ascomycete fungi of the Northern hemisphere and comprises 18 species. The general characteristics of the genus are: medium or medium-large carpophore, with the mitre of irregular shape, brain-like, saddle-like where the hymenium is placed, of reddish brown colour, or brown amber. The stem is short, squat at times, whitish, smooth, sometimes grooved, hollow. The flesh is frail. White spores, ellipsoidal, from smooth to finely warty.

Hymenium: hymenophore, placed on the outer part of the mitre, waved, smooth. Stem: x 1, cm, initially cylindraceous, then compressed and sulcate, pruinose, brown-pale then reddish or grey-lilac, even pale pink, hollow with septa and chambers grooving it inside. Flesh: thin, elastic, coriaceous, whitish, reddish, with mushroomy odour and pleasant taste.

Habitat: saprophyte fungus. It grows in the conifer or mixed woods, on the litter and on woody residuals or in burnt zones, even on sawdust or on hard packed soil, in summer-autumn. Edibility: toxic; contains gyromitrin, toxin which, when metabolized by the body, is converted into monomethylhydrazine, a volatile hydrazine, component of some fuels for rockets.

Cylindraceous paraphyses, thin, serrate, much ramified, apex with brownish granular pigment. Remarks: it could be mistaken with: Gyromitra esculenta Persoon Fries , which however has a rugose surface brain-like , not waved or irregular like Gyromitra infula; Gyromitra ambigua P. Karsten Harmaja , quite similar in the appearance, so much that usually it is not possible to separate the two species without examining their microscopic characteristics, Gyromitra ambigua has the violet tints on the stipe more pronounced and bigger spores, the saddle-like mitre which at times might lead to mistake it with some species of the genus Helvella, but these last usually do have more grey colours and thinner and more grooved lobes.
