Specimen notes
Public Note:
On foray table as 'Psathyrella asperospora'. Spores verrucose - this a Lacrymaria and Watling in NRBG combined aspersopora into Lacrymaria. However, there is clearly a lot of confusion here. Some pictures of Australian taxa under this name show a stout and distinctly squamulose lower stem. See http://www.elfram.com/Fungi/Fungi2/foray_sun_Lacrymaria_asperospora_6-6-e.jpg and http://fungimap.rbg.vic.gov.au/fmn/fmn20.pdf. These do not agree with velutina, do agree with Cleland's original circumscription, but not really Watling's re-description (I don't think 'shaggy fibrils' quite does it justice). Horak 1971 has Cooke's NZ Stropharia lepiotaeformis as a Lacrymaria sp. but didn't recombine it, and questions whether veulina is present as an introduction in NZ. Massey mentions Hypholoma stuppeum which is clearly a Lacrymaria with a type in Kew? Given that there are obviously non-velutina indigenous taxa present in Australia it seems reasonable to expect there might also be in NZ. So the question is whether NZ collections are velutina, asperospora, stuppeum, lepiotaeformis (whatever that is) or something else, or all. Microscopically Watling differentiates the velutina/asperospora on the basis that asperospora has spores with a more obvious supra-hilar depression, more 'mulberry-like' flat-topped tuberculae, black rather than red-brown pigmentation, and accentuated germ-tube. However his spore drawings don't emphasize much of this other than pigmentation. For UK velutina ranges Q1.6-1.8, Oz velutina Q ranges 1.5-1.8 (1.68) and for asperospora 1.4-1.6(1.52). Horak's 'Lacrymaria' lepiotaeformis has Q=1.4-1.7(1.58) and verrucae not confluent, and stuppeum Q=1.7. I would say that microscopically at least lepiotaeformis = velutina. In this collection spores 12x7(1.7), 10 x 6 (1.7), 11x6.5 (1.7), 11x7(1.6), 11.5x7(1.6) um, spore pigment reddish-brown and confluent, cheilocystidia capitate. This collection has the Q of velutina and the spore pigment/confluence of asperospora and the macroscopic features of velutina auct Europe and asperospora sensu Watling but not asperospora sensu auct Oz pics p.p. and Cleland. Later collections indicate NZ has both L. velutina and asperospora and that stuppeum and lepiotaeformis are both asperospora.
