Helotium quintiniae Dennis 1961

Apothecia gregaria, stipitata, cyathiformia, disco vix 1 mm. lato, castaneo, excipulo ex hyphis elongatis, parallelis, 5-6 µ crassis contexto. Asci clavati, octospori, 55-60 x 4-5 µ, apice subacutati, jodo coerulescentes; ascosporae monostichae vel subdistichae, hyalinae, continuae, ellipticae, 5 x 2 µ; paraphyses filiformes, 2 µ crassae, apicem versus baud incrassatae.
The densely clustered apothecia suggest the presence of some kind of stroma within the bark but I can detect neither sclerotium nor black line in sections cut through the bark beneath the clusters. I am, therefore, constrained to refer the species to Helotiun instead of to some genus of the Sclerotiniaceae as its appearance would at first sight suggest. Pseudohelotiurn microcenangium Penz. & Sacc. looks rather similar but with shorter stipe and apparently a different structure, 'contextu excipuli parenchymatico flavicante'.

Spores 5 x 2 µ.

Helotium quintiniae Dennis 1961

[Notes from Kew Type specimen, PRJ 2010] On bark amongst sooty moulds. There are other collections in PDD given this name, need to check them. Type with translucent brown apothecia with long, thin stipes, looks a bit like a Crocicreas. – but no mention of gelatinous tissue in description. Small apothecia barely visible in the photos
