Hi All, 

Recently I found this orange Disco growing with Marchantia and mosses in a damp, shady corner close to farm buildings. Details are as follows:


Ascomata 4-7mm. Shallow bowl shaped when young, becoming discoid, sometimes with a lobed margin. Excipulum downy with hyaline/whitish hairs. Hymenium orange.
Ascospores ellipsoid, smooth, with granular contents, without guttules, 31-37.5x16.5-18.5.
Asci 245-305x27.5-35.
Hairs hyaline, thick-walled, septate, sometimes with mucilaginous deposit, 190-500x7.5-12.5, 
some with a swollen basal cell. Marginal hairs wider, ones further down more slender and grading into rhizoids. 
Paraphyses very pale under microscope, swollen to 6-10, septate. 
Excipulum more or less a Textura Globosa with ellipsoid, thick-walled cells with walls up to c3 thick.
Asci and ascospores dextrinoid in Melzer's.

This taxon appears to be bryophilous/parasitic with rhizoids attaced to living mosses and Marchantia. I have considered Neottiella, Cheilymenia and Octospora but none seems to quite fit. 

Seasons Greetings, 

Charles.
