Specimen notes
Public Note:
17th Fungal Foray of New Zealand; On the base of a dead nikau palm frond. Apothecia numerous (crowded), small, whitish to pale yellow, non-stipitate with beautiful \rquotecrenulate\lquote or raised \rquotecrystalline\lquote deposits (Spooner calls this \rquoteresinous matter\lquote) over the excipulum surface. Asci clavate-cylindrical, 8-spored with a small refractive apical ring staining blue in Melzer\lquotes. Young ascospores forming in a common bundle in the apical half to 2/3\lquotes of the ascus; enlarging spores slipping away from their common bundle and filling the ascus as they mature. Paraphyses numerous, not observed in detail. Ascospores long, narrow, hyaline, smooth, usually somewhat curved, with apices narrowly rounded and usually aseptate although some had a faint median septum. Other septum-like bands were occasionally seen (the latter being interpreted as the junctions between vacuoles). Ascus-free mature ascospores 70-80 X 2-3 µm (n=10).
This species matches its descriptions in Spooner, B.M. 1987. Helotiales of Australasia: Geoglossaceae, Orbiliaceae, Sclerotiniaceae, Hyaloscyphaceae. Bibliotheca Mycologica 116: 711 p. (pages 484-487) and more recently in Zuang, W.Y. & Hyde, K.D. 2001. New species of Lachnum and Perottia from Hong Kong, China. Mycologia 93(3): 606-611. This species is also represented on the Landcare website by 11 collections (including this collection) from the northern portion of the N. Island \endash of which ten are from nikau and one from Dracophyllum latifolium (neinei; spider wood).
