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

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.

Scattered. Cups 1-2 mm. broad, sessile, or substipitate, concave, reddish flesh colour, margin fringed with hair-like scales; asci cylindrically-clavate, 8-spored. Sporidia oblong-fusiform or clavate, sometimes bent, .02-.025 x .005-.006 mm., paraphyses filiform, slender.

On rotten wood. New Zealand (Colenso, 100, 380).

On rotten wood, Colenso B100; B380.

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.

Colenso B380 is labelled 'Margin red and ciliate' but that of the dried material is now perfectly even.

[Notes from Kew Type specimen, PRJ 2010] Kew images. Two Colenso collectionms, b100 and b380. Robusts discs with broad and short stipe, discs orange-brown, with small, hair-like elements around margin. Some discs with dense, whitish, crystal-like layer, especially near margin of dsics. These very distinct on collection b100, but not really evident on B380. Beaton No. 39 collection with broad cupulate, short-stipitate to more or less sesiile disc, dries orange brown (note that white when fresh), clustered in small groups, prominent hair-like elements around edge of cup. Section with the packet - dried up but excipulum looks like has broad-cylindric, nongelatin ous cells.,
