Young ascospores are unicellular and rather clensely filled with protoplasm. The septum<br />
,lc.yclops late and the spore becomes iilcreasingly hpaline.<br />

Type: iIiicroglae~1a Wallrothiam Koerb. The type of Thelenella is T. ntodestn Nyl. Chromatoch!amys<br />
was based on l7er?-ucaria gelatinosa Ach.; V. ntzlscicola Ach. and 17. spltinctrinOides<br />
Nyl. Lrrykenia was based on V. thelostontoidas Nyl., V. luridella Nyl. and 1'. modesta Nyl.<br />
Weitenzvebera Koerber non Opitz was based on 7'. ntzcscorzcnt Fr. and V. sphinctrinoides Nyl.<br />
The type of Limboria Stein is L, corrosa Koerb. Stein attributes the genus to (Ach.) Mas. and<br />
s~parates it from Microglaena on the asteroid splitting of the ostiole. Lintbovin Ach. was composed<br />
of wholly discordant elements, none of which belongs in .Hicroglaena as at present understood.<br />
Phaeoglaena Clements was based on no type and was omitted from his second edition<br />
(Clements & Shear).<br />
Thallus crustose, uniform, often slimy, algae palmelloid. Perithecia immersed in thalline<br />
warts or more or less free, spherical to conical ; wall thin and hyaline, darlcened above with<br />
umbilicate or asteroid ostiole; paraphyses slender, branched, persistent; asci long, cylindrical,<br />
2-8-spored; ascospores hyaline, yellowish or brownish, ellipsoidal, muriform.<br />

Thallus 220p thick, buffy brown, very smooth, almost shining, continuous, outer 2OP decomposed<br />
aud gelified, algae occupying a layer 150p thick, protococcoid, cells spherical, 7-8p in<br />
cliameter, irregularly arranged, hyphae very slender, more or less vertical between the algal cells;<br />
mednlla with hyphae more irregularly arranged and containing an occasional algal cell.<br />
Spermogonia immersed in the thallua, irregularly flask-shaped, wall hyaline about 20~ thick<br />
in the venter, thinning toward the ostiole; spermatiophores forming a dense palisade lining the<br />
venter, about lop long, cutting off slender bacilliform spermatia about 3 X lp.<br />
Perithecia semi-emersed, 390p in diameter, p rojecting about 225p above the level of the thallus,<br />
ostiole rather wide and not clearly diflerentiated; perithecial wall about 100p thick on the<br />
sides, filamentous of more or less periclinal hyp hae, blackened above the thallus, hyaline below,
