Summary: {See also Dacrymyces Table.} Dacrymyces aquaticus is differentiated from other Dacrymyces species by the habitat on wood floating in fresh water or on wood in very wet areas, and by characteristics of the spores and arthroconidia.
Microscopic: spores 8.5-11(12) x 3.5-4.5 microns, "curved-cylindric, aseptate when shed and remaining so at germination or, more often, becoming 1-septate, rarely 2-septate", "germinating only by germ tube, i.e. no conidia are formed on spores or germ tubes. Arthoconidia 4-6(6.5) x 2.5-3.5 microns, ellipsoid, 1-celled, binucleate, produced by fragmentation of hymenial hyphae"; probasidia (26)33-42(48) x 3-3.5 microns at apex, tapering to 2-2.5 microns wide basally, epibasidia 12-33 x 2.5-3 microns, those of a single basidium often differing in length; hymenium amphigenous, of both arthroconidia and basidia arising side by side and from the same hyphae, the basidia sparse and scattered; hyphae (2.5)3-4.5(5) microns wide, without clamp connections, infrequently branched, often with thick gelatinous walls, smooth
Notes: It is found in BC (Bandoni(6)).
Habitat and Range
Habitat
gregarious but usually not crowded, on sodden coniferous wood, wood floating in pond, often on sawn timber, common on the undersurface of floating wood, but more often at or near the waterline on partially exposed wood, (Bandoni)
