Collections Examined

HOLOTYPE OF Helotium pseudociliatum Phillips: AUSTRALASIA. NEW ZEALAND. On rotten wood in forests, [no date], Rev. W. Colenso 380 (K).

Notes

I have examined the holotype specimen of Helotium pseudociliatum and find that this species is an Hymenoscypus S. F. Gray. The outer ectal excipulum is composed of a textura prismatica. Dennis (1964) indicated that P. pseudociliatum might be a Cyathicula, but he was not entirely satisfied with that placement. Since no combination in Hymenoscyphus has been made for P. pseudociliatum, it is provided here.

On rotten wood, Colenso B100; B380.

Description

Apothecia scattered, superficial, disc concave, flesh coloured, 3 mm. wide; receptacle soft, cupshaped, smooth, with a minutely crenate margin, seated on a short stout stalk. Excipulum composed of slender, parallel, compact hyphae, 2 µ wide, with thin, hyaline, nongelatinised walls, lying at a low angle, to the surface. Asci clavate, 145 x 11 µ, 8-spored, pore outlined blue in Melzer's reagent; ascospores biseriate, narrowly elliptical to inequilateral, 18-25 x 4-5 µ, nonseptate; paraphyses cylindrical, obtuse, 1.5 µ thick.

Notes
