Description: Fruiting body a stalked sporangium, gregarious, 1.5–3.5 mm tall. Sporotheca globose, usually nodding but sometimes erect, commonly ochraceous to dusky brown to blackish brown, 0.5 to 0.7 mm in diameter. Stalk slender, furrowed, tapering upward, dark brown, 1.5–3.0 mm long. Hypothallus inconspicuous. Peridial net regular, present both above and below, the meshes often somewhat triangular, the nodes dark, prominent, thickened, polygonal or branched, with each node giving rise to five to eight connecting threads and one or more free ends, lowermost nodes elongated and rib-like, connected to the apex of the stalk. Calyculus small, reduced to a membranous disk at the base of the sporotheca; dictydine granules brown, 0.5–2.0 µm in diameter. Spores ochraceous in mass, pale yellow by transmitted light, minutely spiny, 5–6 µm in diameter. Plasmodium lead-coloured, brown, or brownish black.
Habitat: Decaying wood.
Distribution: Reported from Europe (Ing 1999), Asia (Yamamoto 1998) and Australia (Mitchell 1995) but not always distinguished from Cribraria intricata. First reported (as C. intricata var. dictydioides) from New Zealand by Rawson (1937), based on a specimen collected in South Canterbury.
Notes: This species is considered as a variety of Cribraria intricata by many authors and differs morphologically from the latter only in the lack of a distinct calyculus. However, the two forms appear to display differences in their ecological requirements and thus global distributions (Ing 1999), which suggests that they are distinct. As such, C. intricata and C. dictydioides are treated herein as separate species.
