This is the first in a series of articles specifically looking at the microscopic features of fungi found in the field. This blog features The Deceiver Laccaria laccata, commonly found in the woodlands near where I live, and it's relatively easy to find and identify using microscopy techniques.
It was originally described as Agaricus laccatus by Giovanni Antonio Scopoli in 1772 before being placed in its current genus by Mordecai Cubitt Cooke in 1884.
The common name derives from the fact it is extremely variable, and easily mistaken for other waxcaps of similar colour and stages - its is commonly found between June and November in the UK.
In the field, the Deceiver has a textured cap measuring 2-6cm. The cap is convex at first then flattens out as the mushroom ages. The colour can vary between shades of pinks, browns and oranges. The stipe is 2-10cm, and has a fibrous appearance in keeping with other waxcap species and widens at the base.

Microscopy can reveal identification details otherwise unavailable during field observations. In this case, spores were transferred from the gill to water-based slide preparations and viewed under a compound microscope at 400x magnification.
