Notes     (Last Modified On 3/16/2009)
general taxon notes:
Grimmia tergestina is distinguished from other species of Grimmia by the following features: 1) leaves hair-pointed, obviously concave, oblong-ovate, and not keeled; 2) basal leaf margins pale and hyaline, consisting of thin-walled, elongate-rectangular cells; 3) capsules immersed, surrounded by large, differentiated perichaetial leaves, which have membranous and pallid margins (especially the innermost ones); and 4) peristome teeth strongly perforate. The leaf shape of G. tergestina is similar to that of G. laevigata; however, it differs from the latter in having more robust, stiff plants and pale, hyaline basal marginal leaf cells that are elongate-rectangular and rather thin-walled, while G. laevigata has smaller plants, not hyaline basal marginal leaf cells that are quadrate to subquadrate with transverse walls distinctly thicker than longitudinal ones. Sporophytically, the two species are also distinctive. Grimmia tergestina has setae shorter than the urns and capsules immersed in large, specialized perichaetial leaves, while G. laevigata has setae much longer than the urns and capsules exserted.
The specialized perichaetial leaves of G. tergestina are similar to those of Jaffuefiobryum; however, the latter has specialized vegetative leaves as well. In addition, the peristome teeth of G. tergestina are more extensively perforate than other species in Grimmia. Grimmia tergestina is perhaps a species that links Grimmia with Jaffueliobryum.
The definite type material of Grimmia subtergestina was not available for study. There are no specimens of this species from JE, and there were no responses from FI and from G.N. Potanin’s herbarium in LE. According to the original description, “A G. tergestina differt: foliis senioribus depilibus obtusissimis, juvelilibus ad basin late albilo- marginatis,” this species may be conspecific with G. tergestina.

Plants rather stiff, up to 2.5 cm high, yellowish green above, dark brown below, in dense, rigid tufts. Stems sparsely branched, with well developed central strand in cross section. Leaves erect, imbricate when dry, spreading when moist, 2.4–2.8 mm long, oblong-ovate, obviously concave, ending in a more or less long (0.6–0.9 mm), nearly smooth, hyaline hair-point, upper leaves enlarged, with pale hyaline margins along leaf bases; margins plane or somewhat incurved, entire; costa slender, percurrent, in cross section flattened, with small median cells and abaxial small cells; upper cells bistratose, obscure, small, 5–7 µm wide, rounded-quadrate, with thick walls; basal cells elongate-rectangular, 23–40 µm × 7–9 µm, with straight, thin walls, 3–5 rows of cells near margins colorless, hyaline with rather thin walls. Dioicous. Perichaetial leaves much larger and differentiated from vegetative leaves, oblong to oblong-ovate, ending in long awns, strongly concave, margins membranous and pallid, cells rectangular to elongate-rhomboidal, thin-walled. Setae yellowish, straight, shorter than capsules, ca. 0.3–0.4 mm long; capsules immersed, reddish brown, ca. 1.6 mm long, ovoid, smooth or nearly so; exothecial cells rectangular to quadrate, thin-walled; stomata present near base of urns; annuli consisting of 2–3 rows of thick-walled cells; opercula with straight beaks; peristome teeth erect, lanceolate, ca. 0.25 mm long, yellowish brown, split above, strongly perforate to the middle part; outer surface densely papillose in upper 2/3, papillose, with slight vertical strips below; inner surface papillose throughout. Calyptrae mitrate, lobed at base. Spores 9–11 µm in diameter, yellowish, granulose in regular rows.
