On the bark of a live "Viñatigo" (Persea indica), in a laurisilva forest. No more than 2 mm diameter, inside yellow-grenish and white hairs. Asci 8 spores, biseriated, amiloid, with croziers. Paraphysis filiform, not enlarged at the apex and longer than asci. Cilindrical and not septated spores. Hairs filiform, not enlarged at the apex, septated and with granular surface.
Sporal measure (1000x, in water, fresh material)
5.6 [7.6 ; 8.9] 11 x 1.8 [2.1 ; 2.3] 2.7
Q = 2.4 [3.4 ; 4.1] 5.2 ; N = 17 ; C = 95%
Me = 8.28 x 2.22 ; Qe = 3.77
Thank you

Re:Lachnum aff patulum ?
Its Proliferodiscus pulveraceus. Wonderful how you photographed the croziers! This species may sometimes also be without croziers. A good character is the reaction in KOH of the ectal excipulum (also base of hairs): turning violet!
The variable arrangement of the spores inside the asci is only seen in dead asci. In living asci they are always biseriate.
Are your finds all from Macaronesia? Which island?
Zotto

Re:Lachnum aff patulum ?
Yes, all of them are from Macaronesia, from Tenerife: Stictis and Proliferodiscus pulveraceus from "laurisilva" forest, and Propolis aff viridis from eucaliptus forest.
Thank you for "Proliferodiscus pulveraceus", I had never thought in this species.
