Small Coprinopsis growing on woody twigs

Dear friends,

I have this Coprinopsis species about 3cm long with partial veil having intertwined filaments with long warts or tubercles projecting out. Cystidia and pleurocystidia balloon shaped.

Spore size:

7.9 [8.7; 9] 9.8 × 5.7 [6.2; 6.4] 6.9 µm

Q = 1.2 [1.4] 1.6; N = 30; C = 95%

Me = 8.9 × 6.3 µm; Qe = 1.4

Thank you Andreas and Mollisia for helping out.

Host / Habitat: Damp and old stems of dead herbaceous plants

Pleurocystidia size (um):

84.83 x 43.75

86.12 x 48.97

94.08 x 47.90

59.24 x 33.06

58.74 x 35.24

83.79 x 47.61

90.78 x 45.38

Location Gozo (Matlese Islands)

These photos are from an old collection and I don't remember much about it, or if I have a specimen, but this photo shows clearly spores in the range of 8.5-9.5um length and pleuro- (or cheilo-) cystidia that are broad and short. I hope there weren't two or more specimens of different species close to each other and have a mixture. The substrate was annual herbaceous plants (maybe grasses?) that dried out in summer and then this fungus grew after the autumn rain.

It is a very curious Coprinopsis. Many things match for goudensis too, although admittingly the velar hyphae do look thick (but how important is this?). Then the habitat for goudensis is lignicolous and in my notes, I have written dry debris of herbaceous plants, but I have not checked very carefully the debris and maybe it was mixed with some slender twigs?!?! I can see parallel ridges along the substrate indicating herbaceous stem that dried out but I don't know which and again it is a bit (very bit!) thick and lignicolous. Ajjj!

Hre it is photographed on narrow 'twigs'

I still have the specimen. Is it of further use to recheck something?

It is OK Andreas - thanks so much for trying to help (and you did too both in this post and previous ones too!)

Hello Steve,

can't judge that, I'm too less experienced in this group of ink caps. I think that is something for coprinus specialists.

all the best,

Andreas

So as expected, the old dry specimen could not offer much valuable data over what I already doucmented. The spores are confirmed, the hymenium is completely eroded, the veilar remnants are artistically elegant, with brownish contents and as rather thick-walled (?), but I could just add that I have seen clamp junctions at the filiform structural hyphae; if this is of any relevance.

I attach another image of the pleurocystidia from the fresh specimen, assuming that they are Cystidia,
