Remarks (internal):By virtue of the giant spores with their peculiar heterogeneous type of ornamentation both as to the amyloid reaction and the shape and size of the elements of the ornamentation themselves, the species is readily distinguished. The lack of sphaerocysts is significant. Zeller's illustration (fig. 19, 1.c.) does not show the filamentous structure of the mediostratum as distinctly as Smith observed it on the type, but his indications of its existence are clear. Consequently we have no hesitation in transferring the species to Martellia.

Description:Martellia ellipsospora (Zeller) Singer & Smith comb. nov.
Hydnangium ellipsosporum Zeller, Mycologia 31:13. 1939.
Gastrocarp 1-2 cm tall, 1-1.3 cm broad, subglobose, usually taller than broad, smooth but outer layer flaking off in age at times, white to pale ochraceous-buff, occasionally with large white rhizomorphs adhering to surface; gleba cream-color, becoming ochraceous-buff, cavities medium size, "empty"; columella none and no stipe or sterile base present.
Spores 15-20(23) x 12-15(16) µm, broadly ellipsoid, ochraceous in dilute KOH, thin-walled and wall nearly hyaline in Melzer's reagent ; sterigmal appendage prominent in some of the smaller spores, usually inconspicuous in larger ones; ornamentation of irregular warts, short ridges and spines and 1.3-2.5(3) 0.4-1 µm strongly amyloid or amylaceous material denser over the elements of the ornamentation in some places than in others and usually darkest at or near the apex, sometimes strongly amyloid on one side of a wart and not on the other, the long narrow elements often bent or crooked, many fine lines and granules of amylaceous material present and connecting the major elements of the ornamentation; plage area covered with amyloid ornamentation in the form of lines and granules.
Hymenium. Basidia 30-42 x 11-15 µm, mostly 1-spored rarely 2-spored, broadly clavate. thin-walled, hyaline in KOH; those with a sterigmata resembling mucronate cystidia. Cystidia none. Basidioles present, clavate to ellipsoid. Pseudoparaphyses resembling inflated basidioles.
hyphal layers. Subhymenium cellular, cells sphaerocyst-like and in age quite inflated (10-20 µm) ; mediostratum a narrow band of interwoven hyaline, branched filaments 4-7 µm in diam., hyphal cells of equal (or nearly so) diameter throughout. Epicutis of peridium as described by Zeller - an outer compactly interwoven layer of narrow hyphal filaments 3-6 µm in diam., the walls thin to slightly thickened but not at all gelatinous. Context of more loosely interwoven hyaline hyphae 5-8 µm in diam., no sphaerocysts found; clamp connections none.
Under conifers, Benton and Clackamas Counties, Oregon, June to August. The type was from under Douglas fir, Alsea Mt. Oregon. June. 1937. Coll. 1). P. Rogers. (NY).
