Descriptions
Sori (Fig. 18) in ovaries, long cylindrical, contorted or looped, 1.5-2 x 25-50 mm, covered by an ashy-grey membrane which ruptures longitudinally to expose the granular-powdery mass of spore balls and spores intermixed with irregular groups of sterile cells, and a long, central, flagelliform columella. The distal part of the sori may be empty while the proximal part may still contain immature, agglutinated spore masses. Spore balls (Fig. 16) loose, irregular, many-spored, readily disintegrating. Spores (Figs. 16, 17) globose, subglobose to broadly ellipsoidal, 6-8.5 x 7-10 µm, reddish-brown; wall 1-2.5 µm thick, finely tuberculate to coarsely echinulate (0.5-1.5 µm) under SEM, more pronounced on the free surface of the peripheral spores. Sterile cells (Fig. 16) subglobose, ovoid to slightly irregular, 5.5-11 µm long, thin-walled (ca. 0.5 µm), hyaline, smooth, with 1-2 oil droplets. Spore germination (on WA, at room temp., in one day; Fig. 19) results in septate basidia which disintegrate readily producing lateral and terminal, ellipsoidal basidiospores measuring 1-1.5 x 3-6.5 µm.
Sori (Fig. 18) in ovariis, longe cylindrici, contorti vel spiralisati, 1.5- 2 x 25-50 mm, membrana cinerea cooperti; membrana longitudinaliter rupta massam granulosam-pulveream glomerulorum sporarum et sporas cum gregibus irregularibus cellularum sterilium immixtis, deinde columellam longam, centralem flagelliformem ostendens. Pars distalis sori forte jam evacuata, sed pars proximalis adhuc massas sporarum immaturarum agglutinatas continens. Glomeruli sporarum (Fig. 16) laxi, irregulares, polyspori, leviter disintegratae. Sporae (Fig.16, 17) globosae, subglobosae usque late ellipsoideae, 6-8.5 x 7-10 µm, rufobrunneae; pariete 1-2.5 µm crasso, leniter tuberculato usque dense echinulato (0.5-1.5 µm) sub SEM, magis conspicue in parte libera sporarum peripheralium. Cellulae steriles (Fig. 16) subglobosae, ovoideae usque parum irregulares, 5.5-11 µm longae, tenuiter tunicatae (caa. 0.5 µm), hyalinae, leves, cum 1-2 guttulis oleosis. Germinatio sporarum (agaro aquoso, temp. conclavis solita, 1 dies; Fig. 19) basidia septata leviter disintegrata, basidiosporas 1-1.5 x 3-6.5 µm, laterales et terminales, ellipsoideas producentes efficiens.
