Cribraria argillacea
(Pers. ex J.F. Gmel.) Pers. 1794
Description:
SPOROCARPS: dull ochraceous-olivaceous, globose, nearly 1 mm. in diameter, sessile or short-stipitate, closely gregarious or crowded, the peridial walls at maturity smooth, shining, except above, long-persistent, obscurely reticulate, with irregular thickenings which at the apex at length present the appearance of an irregular, coarsely meshed net without nodal thickenings;

PERIDIUM: silvery, evanescent;

Stalk:when present, very short, stout, erect, reddish brown;

Possessing the reticulations and plasmodic granules of Cribraria. In freshly formed sporangia the reticulations are barely visible in the crown; later on they are more manifest, until, as spore dispersal proceeds, the cribraria characters come out with sufficient distinctness, and in empty sporangia the reticulations may be seen to affect the entire peridial wall. The nodes are not expanded

SPORES: spore-mass ochraceous; spores by transmitted light pale yellow, spinulose, 5-7 µm diam.

PLASMODIUM: lead colored, scanty.
HABITAT: Decaying wood, especially that of conifers.

DISTRIBUTION:
cosmopolitan, known from Auckland, Northland, and Southland.
