Hygrophoropsis macrospora is a species of fungus in the family Hygrophoropsidaceae. It is found in Europe and North America.

Taxonomy

Formally described by Derek Reid in 1972 as a variety of Hygrophoropsis aurantiaca,[1] it was raised to distinct species status by Thomas Kuyper in 1996. Hygrophoropsis pallida (Peck) Kreisel is a synonym that was never formally published. It is based on Charles Horton Peck's taxon Cantharellus aurantiatus var. pallidus, which he published in 1896.[2]

Description

Fruit bodies of Hygrophoropsis macrospora have a cream- to tan-coloured cap with a felt-like surface texture. The gills are forked and yellowish, with a decurrent attachment to the stipe.[3]

Hygrophoropsis macrospora differs from H. aurantiaca mainly by its larger spore size, measuring 8.0–11.0 (sometimes up to 13.0) by 3.0–4.5 (5.0) μm. In comparison, the spores of H. aurantiaca have a shorter length, usually 5–8 μm, and a similar width.[4]
