Species Information
Summary: Nectriopsis violacea forms a layer on Fuligo septica of purplish subiculum and purple pear-shaped bodies each with an opening at the top. The anamorph is Acremonium fungicola (Sacc.) Samuels.
The accompanying photograph by John Davis from WA on Fuligo septica. There is a collection at University of British Columbia from BC on Fuligo, and it is also reported from Haida Gwaii in BC. N. violacea is presumably found elsewhere in North America (Seaver(6) was examining a collection from Maine which referred here except that although the spores were sometimes pseudoseptate they were not septate). It occurs in Europe including Denmark, Finland Norway, and Sweden, (Hansen, L.(1)), and United Kingdom (Dennis(1)).
Fruiting body: perithecia and subiculum forming a layer in shades of violet, (Hansen, L.), stroma consisting of "a thin, white mycelial growth overspreading the substratum"; "perithecia thickly scattered, globose or subglobose, smooth or only minutely roughened, vertically collapsing, violaceous", (Seaver)
Microscopic: spores 6-8 x 2.5-3 microns, ornamentation spinulose, 2-celled, hardly constricted at septum, (Hansen, L.), spores 6-7 x 2-3 microns, elliptic, granular within, sometimes pseudoseptate but not septate, 1-seriate or with the ends slightly overlapping; asci 8-spored, cylindric, (Seaver)
