Identification Notes
[edit]- Thin ring, grooved underneath
- Stipe striate with thin fibres, rhizoids at base
- Taste & smell of flour
- Flask-shaped (utriform, non-mucronate) cheilocystidia, approx. 50µ × 22µ
- Spores approx. 8.5μ × 5μ
A. praecox is part of a poorly defined complex of species. This identification follows Funga Nordica[1]. I think A. acericola is ruled out because of the grassy location and A. sphaleromorpha is ruled out because the stem was not bulbous and the cap was not very yellow.
