Descriptions
Helotium novae-zelandiae Dennis 1961
Apothecia sparsa, superficialia, stipitata, 2 mm. alta, disco plano ant parum convexo, luteo, 2 mm. lato, margine integro non prominuio, stipite fibrillose et ad basim atro-brunneo. Asci cylindrico-clavati, octospori, 60-70 x 4.5-5.5 µ, apice jodo non tincti; ascosporae clavatae, hyalinae, monostichae vel subdistichae, 6-7 x 2-2.5 µ, paraphysibus simplicibus, ad apicem obtusis et paullulum incrassatis 2 µ crassis.
This fungus bears considerable resemblance to H. vernalis Dennis but has smaller more clavate ascospores. The excipulum is formed of rows of large, short, thin-walled cells, up to 12 µ wide, terminating in short adpressed fibrils. Rutstroemia fusco-brunnea (Pat. & Gaill.) Le Gal is similar in structure but has a very long slender stipe.
Ad ramum decorticatum, Black Gully, Tapanui, Otago, 19.4.1957, S. D. & P. J. Brook 19039 (typus).
