Article: Dennis, R.W.G. (1961). Some inoperculate Discomycetes from New Zealand. Kew Bulletin 15(2): 293-320. Notes: 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'.

Persoonia 3(1): 29-80. Description: Spores 5 x 2 ยต. Notes: SERIES 6. Cupreum. Stipitate tropical or South temperate species on woody substrata, with
excipulum of parallel hyphae, asci mostly I+ and small rod-like spores
