Specimen notes
Public Note:
[GS] Growing on a very rotten log in broadleaf-podocarp forest. Caps fawn-brown, paler towards the margin, with some blackening in patches, up to 50 mm across. Gills white but with black sooty-like spots that increase in size with age, attached to stem. Stem whitish initially, eventually becoming black and sooty in appearance. Spore print white. [JAC] Microscopically it is stuffed with characters - amyloid spores, black lactifers, hydropid vesicles in the cap. This fits with Hydropus nigrita which is reported as cosmopolitan in tropics/subtropics. We have a few that fall into that category, although Palmy isn't exactly subtropical. First record for NZ. A related species, H. atramentosus=H. fuliginaria (type species of Hydropus) has been sequenced, but not H. nigrita (which has been synonymised in the past). Whether this is the same H. nigrita described from Cuba and reported from South America, Japan, Korea etc, remains to be seen.
