Entoloma henricii is an easily recognized species due to being the only European species with a celullar cap surface.
This species is characteristic Entoloma due to a celullar pileipellis and its unique pink-gilled Dermoloma appearance (Noordeloos 1994). Its primary habitat is non-fertilized grasslands on acid ground. Besides its limited distribution, the habitat loss is the main threat of this species, and the species is rare all over its distribution.
Preliminary global red-list assessment; VU (C2a(i)), continuing decline and < 1000 individuals in largest subpopulation.
Endemic to Europe. Scattered in central and south Europe. Known from not more than 20 localities in Austria, United Kingdom (Scotland, Wales), France, Germany, Italy, Spain and Switzerland. It has apparently a western oceanic distribution in Europe. Rare in all its distribution range.
Although this species is easily recognizable, it has scattered reports and has been cited considerably few times considering that grassland fungi have been subjected to intensive surveys in several European countries. It might be more widespread and overlooked due to its dull colours. Nevertheless, its habitat has strongly decreased in Europe and the populations of this fungus have declined similarly. It has so far been found in 20 localities, but it is conservatively estimated that it might be present in 200 localities. The localities so far known appear to harbour populations with very few individuals.
Its primary habitat are non-fertilized grasslands on acid ground, but Italian collections were made on calcareous ground (Battistin et al. 2008). In the Iberian Peninsula restricted to periodically cut Pteridium communities (Olariaga & Pasaban 2003).
The fertilization of grasslands or the cessation of a traditional management are a primary threat of this species. Due to its reduced distribution and small populations, habitat fragmentation and any change of management of the sites can make its populations disappear.
Maintenaince of traditional use of semi-natural grasslands and protection of sites where it occurs.
