Psathyrella cf candolleana but maybe not ?

I found a clump of four fruiting bodies emerging from dead bark under detritus of carob tree which gave me the indication of a Psathyreall candolleana, but something did not convince me (and another expert had some thoughts too) maybe the lack of violet tinge of the spores, the long stipes, the very glabrous and polished cuticle.

I.only observed the spores for now (size-wise, they match candolleana). Your opinions are welcomed. If many think is not candolleana, I soo further microscopical features from the dried material.

1. It has just rained so the caps are not slimy

2. Spore sizes:

(6.4) 6.8 - 7.8 (8.5) × (4.5) 4.6 - 5.2 (5.4) µm

Q = (1.3) 1.4-1.6 (1.8); N = 30

Me = 7.3 x 4.9 µm; Qe = 1.5

P.S. What happened to Andreas Melzer excellent website about Psathyrella s.l.

hi and tnx Schupfnudel

To remove the doubt I checked more micro features to find the following: No pleuro, spores with evident germ pore, Cheilocystidia in tufts, narrowly utriform with rounded apices, without yellow crystals, 45-75um long. For me this puts the specimen into Psathyrella candolleana or the new (if broadly accepted) genus Candolleomyces.

I used an oldish Melzer key in english update 26/9/15 which was used to be in the great website vielepilze.de and now there are only flowers. Pity that site had gone or maybe it is hosted in another URL ?!> I thought something serious had happened to Andreas so glad to read he is still active on Psathyrellaceae

Many thinks for the link/paper, I try to trace it down

P.s. what is the last key you have in English? Any newer from 2015 ?
