Descriptions
Helotium subcinnabarinum Dennis 1961
Apothecia sparsa, stipitata, cinnabarina ('English Red' vel 'Dragon's Blood Red', Ridgway), cupula planiuscula, latit. 1-2 mm., stipes subaequalis, altit. 1-2 mm., deorsum leviter flocculosus. Asci cylindraceoclavati, 70-80 x 6 µ, octospori, obturaculo minimo jodo obsolete vel vix coerulescente; ascosporae eilipticae vel clavatae, 8-9 x 2-2.5 µ; paraphyses gracilescentes, crassit 1.5 µ.
The structure is somewhat intermediate between that of an Helotiun and a Phialea, with the flesh composed of slender interwoven hyphae with slightly gelatinised walls, the hyphae becoming almost parallel but still undulating at a low angle to the surface in the excipulum. The red pigment is unaffected by ammonia but completely decolorised by lacto-phenol.
Supra folia Elaeocarpi dentati, Harihari, Westland, 8.11.1954, Dingley 19052 (typus).

[Notes from Kew Type specimen, PRJ 2010] Type material at Kew with very few apothecia. Receptacle translucent ornage brown, glabrous; stipe quite long and broad, cylindric, lower part of stipe with dense weft of fine, white mycelium.
