Descriptions
Helotium allantosporum Dennis 1961
Apothecia subsparsa, superficialia, brevissime stipitata, umbrina, leviter pubcrula, 2.5 mm. lata, margine integra. Asci cylindracco-clavati, apice jodo non tincti, octospori, 60-70 x 5 µ; ascosporae oblongato-ellipsoideae vel allantoideae, distichae, continuae, 8-9 x 1.5 µ; paraphyses filiformes, 1-1.5 µ crassae, apicem versus baud incrassatae.
Flesh dark brown throughout, composed of loosely woven purplish-brown hyphae 3-4 µ wide; excipulum composed of parallel, brown, thin-walled hyphae lying at a low angle to the surface, their tips running out into 1-2celled cylindrical hairs, with the tip cell inflated to 8-10 µ diameter. These hairs recall those of Chlorosplenium versiforme but the fungus completely lacks green or olive tints and can scarcely be referred to that genus.
Ad cortices arborum frondosarum, Huia, Auckland, 4.5.1957, J. D. Atkinson 19034 (typus).
