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.
It is found in BC (Bandoni(6)).
Fruiting body:
typically less than 0.1cm in diameter, sometimes confluent and reaching 0.3-0.4cm across, about 0.05cm high, orbicular to elliptic, pulvinate [cushion-shaped], flattened slightly, gelatinous in consistency, attached weakly by a point; at first pallid yellowish becoming "apricot yellow" to "light orange yellow", "cadmium yellow" or "orange", brownish when old and "ochraceous orange" to "zinc orange" or "ochraceous tawny", (colors from Ridgway); smooth or commonly slightly roughened, (Bandoni)
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
