Growing on fallen twig of Picea sitchensis

Apothecia dry and incurled when found; hydrated as images – possibly erumpent. Inamyloid in Melzer’s.
Spores 5.6-8.6 x 2.1-2.6 µm, smooth with two guttules.
Asci 35-41 x 5-5 µm
Paraphyses filiform with some branching.
I’ve failed to key this out and would welcome any suggestions.

Re: Hyphomycete

Sistotrema sp.

Growing internally on rotting Sitka spruce (Picea sitchensis).
Spores inamyloid: 5.6-7.0 x 3.7-4.6 µm.
Basidia predominantly 6-spored: 20-23 x 7.3-7.7 µm.
Hyphae with clamps: 3.3-4.3 diameter.

It's the spore size and shape that I can't fit to species.
Any help welcome.

Regards, Chris

Hyphomycete

Growing on the dead stems and leaves of Triteleia laxa.
Conidia smooth, 0-3–septate, 8.8-14.7 x 4.6-5.9 µm.
Possibly one of the numerous Cladospora species, but I am unable to key it out so any help welcome.

Re: Fungi on dung

I have only found this once, on pony dung, but it's probably not scarce. I endorse Chris's comments especially regarding willing helpers.

Re: Taeniolella arthoniae in the New Forest, New to Britain

Another interesting post, Neil - lichenicolous fungi are fascinating.

Your link hasn't worked for me but the monograph can be downloaded from here: https://www.ingentaconnect.com/content/ ... ic-live-02#
