Remarks (internal):This is macroscopically similar to some variants of Dacrymyces palmatus (Schw.) Burt which I have frequently collected in Louisiana both on coniferous and frondose wood (Lowy, 1955) . I have also examined collections from Mexico and Argentina that coincide quite closely with the Louisiana material. Reid (1974) believes it is "somewhat dubious" that D. palmatus occurs in those two countries, since I reported the presence of clamp connections in the specimens examined (Lowy, 1971) . However, Kennedy (1956) also noted that the hyphae of this species are found to be "ocassionally with bulbous septa or clamp connections," although the latter were "rarely seen." She concluded that "clamp connections may be present at an early stage, since bulbous septa and collapsed clamp connections would suggest this condition" and Martin's (1952) description of the species includes the observation that there are "occasional or frequent clamp connections, these apparently lacking in some collections."
Of the seven species of Dacrymyces that I have seen from the American tropics, only D. palmatus has 7(-9)-septate basidiospores and is easily distinguishable from D. falcatus Brasfield which has strongly falcate basidiospores, some of them up to 16-septate. Dacrymyces ancoratus also differs from D. palmatus in basidiospore size, tlie latter measuring 18.5-22.5 x 6-8 µm. Another but more variable difference appears to be the number of conspicuous, radicating bases found in the new species. If the wet basidiocarp is carefully separated from the substrate, these may be observed. In D. palmatus, Kennedy (1958) and others have noted that "a white, radicating base," is present. I liave found tliis characteristic to be rather variable and some Louisiana collections have more tlian a single holdfast. The type collection of D. ancoratus has several such bases which tend to be somewhat smaller than those of D. palmatus. It commonly occurs in D. palmatus that the basidiocarp is pustulate in origin, then becomes convolute to flabelliform or even cerebriform. Fusion of parts of the gelatinous sporophore is common and results in the formation of a compound structure each section of which may form a radicating base underlying the fused basidiocarp, a phenomenon that is well exemplified in D. ancoratus.
