Clitocybe agrestis
Clitocybe agrestis is a species of agaric fungus. Widely distributed in Europe, it was described as new to science in 1969 by the Finnish mycologist Harri Harmaja. Fruitbodies are poisonous as they contain the toxin muscarine.
Taxonomy
Clitocybe agrestis was formally described by the Finnish mycologist Harri Harmaja in 1969. The holotype was collected on 11 October 1968 along a roadside near Läby in Uppland, Sweden; an isotype is preserved at the herbarium of the University of Michigan. The species epithet agrestis means "of fields".Description
The cap near the stipe and narrowing towards the edge. When fresh they are whitish to faintly brownish; in dried specimens they acquire dirty brown tones similar to the cap and stipe. The smell is faintly fruity—often likened to strawberries—and becomes more pronounced as the fruit bodies dry. The taste is mild and fungoid.Microscopically, the spores measure 4.5–5.8 by 2.9–3.3 μm, are broadly ellipsoid to oblong with an obtuse base, and often occur in tetrads; the apiculus is about 0.6–0.7 by 0.3–0.4 μm. The spore print is pinkish‑buff. The cap cuticle is 60–100 μm thick, comprising subparallel to interwoven hyphae 1.5–4.5 μm wide with faint intracellular pigment; the underlying subcutis is not clearly differentiated.
