If there are experts who study leucopaxillus / Clitocybe I have found this interesting species Under Cistus monspeliensis, here in Malta. I have tentatively identified it as Leucopaxillus paradoxus for its gross physical characters (robust habit, browning areas in pileus, thick stem, dry chamois-like texture, taste above-average bitter, lamella cream-caramel) and somewhat the micro too: Cheilocystidia not observed, spores large about 7-8 µm 15.5 x 7.5 um. Unfortunately, I had not much time to work on it as I collected other fungi which I gave more priority. I read that this species was recorded under pine and oak ... so maybe it is host-variable. The appearance is very matching.

Hi Steve
Your first idea ist probably right.
I have found L.paradoxus a lot of times in coniferous needle litter. This fungus is not host specific, its a saprobiont which likes a lot of different types of organic material
To aprove the determination
you have to check the spores in Melzer/Lugol , they should have an amyloid ornamentation (spines)

Here I am back after finding the ex-siccatum and examined again the spores more carefully under Melzer and Baral Iodine (a stronger version of Lugol's)
1. I think they are inamyloid
2. The spore size is larger than in the first examination, and they average 15.5 x 7.5um.
This large size of the spore might be helpful. Are we still in Clitocybe with these large spores? What about Lyophyllum (Ossicaulis or other genera?) Which like to form fused stipes!

Good morning, Steve!
I hope, Uwe could help. I am curious, which fungus it will turn out.
Sincerely,

thats strange, your sure you measured the spores with 400x and not with 1000x ???
I have no idea which white fungus has such large spores.

Uwe and others who are interested in this fungus, I had time to carry out the examination of the pileipellis. Many parts did not preserve well, but I could see a trichoderm of wavy or almost straight cylindrical hyphae, hyaline, with terminal cells having a very obtuse or truncate ending, and I could not see any clamp junctions.

UweYes, I was also puzzled. I had in mind this strange thought of some sort of Asterophora and we are seeing Chlamydospores ?!?! However this is a parasitic genus right?. I can redo the spores but I am absolutely sure I was under x400. Spores from a contaminant fungus during dehydration is also possible, but again... low possibility.
