Following the suspicion mentioned in the comments for the classification of these specimens, I contacted the Editor/Assessor of the species Hygrocybe monteverdae, Eef Arnolds, at Fungal Red List (http://iucn.ekoo.se/iucn/species_list/) and here are some comments that he sent me:
“As far as I can judge from your photographs, your collection belongs to Hygrocybe monteverdae indeed”
and
“I saw the last photograph on the site illustrating dried specimens. It is the most diagnostic photograph of all, since the blackish or dark brown decoloration of exsiccata is highly characteristic for H. monteverdae and does never occur in H. virginea or H. pratensis var. pallida. Congratulations with this rare record!”

Microscopy added. Hygrocybe monteverdae possible?

These two specimens were found at a border of a forest dominated by Castanea sativa, among some herbaceous plants and some burried wood from small shrubs. They are very similar to Cuphophyllus pratensis, but have some differences: the habit is slender, the stem is very light pink (see the photos where some pinkish hue can be understood) and, as a distinguish feature, the mature specimen has some brown coloration at the margins of the cap and of the hymenium. Going to the microscopy I measured the spores, for which got the following dimensions:
(6.2) 7.3 – 9.5 (12) x (4.2) 4.7 – 5.5 (6) µm
Q = (1.2) 1.4 – 1.9 (2) ; N = 50
Me = 8.4 × 5.1 µm ; Qe = 1.6.
These values are a bit to high for C. pratensis that, according to Flora Agaricina Neerlandica (Vol. 2), have dimensions:
5.5-7.5(-8.0) x 3.5-5.5 um, Q=1.2-1.6(-1.7), Qav=1.3-1.55.
Recently I consult the page of The Global Fungal Red List (http://iucn.ekoo.se/iucn/species_list/) and saw there photos of the species Hygrocybe monteverdae (that was never transfered to the genus Cuphophyllus) and a short description, separating it from C. pratensis by the black discoloration on drying and larger spores. Since my specimens, maily the mature one, become dark brown on drying I think that the species Hygrocybe monteverdae is a candidate for this observation.
