Article: Dennis, R.W.G. (1961). Some inoperculate Discomycetes from New Zealand. Kew Bulletin 15(2): 293-320.
Description: Apothecia gregarious, erumpent, sometimes proliferating from the margin, disc pale cream, up
to i mm. across; receptacle white, short-stalked, hairs cylindrical or slightly tapered at the tip,
rather thick-walled and stiff, hyaline, granulate, multiseptate, up to 110 x 2.5-3 µ; asci clavate,
stipitate, apex rounded, not stained by Melzer's reagent, 40 x 4 µ, 8-spored; ascospores
uniseriate, globose, hyaline, 1.5-2 µ; paraphyses cylindrical, 1 µ thick.
Notes: I have retained the traditional division of hairy, corticolous, subsessile Helotiales with
cylindrical obtuse paraphyses and asci with negative iodine reaction into Lachnellula Karst.
(1885) with spherical ascospores, Trichoscyphella Nannf. (1932) with ascospores of any other
shape on conifers and Perrotia Bond. (1901) on other woody plants, usually with cylindrical
septate ascospores and coloured hairs. There seems little to justify this division at the generic
level, however, especially in view of Perrotia alba described above, with hyaline hairs but not
on a conifer. If they are reunited but still kept distinct from Dasyscyphus S. F. Gray (1821),
Trichopeziza Fuckel (1870) and Belonidium Mont. & Dur. (1846) the oldest generic name will
apparently be Lachnellula. In 1907 Boudier already united Trichoscyphella and Lachnellula
but under his own invalid generic name Trichoscypha (1885), a later homonym of
Trichoscypha Hook. f (1862) in the Anacardiaceae.
