106 Prof. Santo Garovaglio on thé Species of 
cially as A. Kochianus, Dunker (loc. cit. figs. 7, 8) appears to be 
the analogous variation of A, hians. If this view should prove 
to be right, we shall have a fourth form (forma agglutinans), 
the rarest of all, being as yet exemplified only in two of the 
three species. 
XIV.—Notule Lichenologice. No. XVI. 
By the Rev. W. A. Leicuron, B.A., F.L.S. 
Pror. Santo Garovaciio has favoured us with a copy of a 
further portion of his ‘Tentamen Dispositionis Methodice 
Lichenum,’ comprising the Verrucarie quadriloculares, and 
illustrated with three plates. 
Secrio III. 
Verrucarie quadriloculares. 
Saxicole vel corticole ; hermaphrodite, monoice vel dioicee ; 
epithecium breve, dimidiatum, subintegrum, carbonaceum (in 
una alterave specie coloratum ; paraphyses nullz, obsoletz vel 
distinctze, simplices aut ramose, continue vel in frustula solute, 
capillares vel articulate ; asci lineares vel clavato-elongati ob- 
ovative, interdum circa medium ventricosi, interdum supra basim 
saccato-gibbi, octospori; spore in duplicem triplamve seriem, 
rarius (Cohors IV.) uno ordine altera super alteram disposite, 
figura et magnitudine varie, s. ovoidez, obovate, in formam 
cocci, bombycis, vel fusi, in cohorte III. gracillime, aciculares, 
in reliquis sat crassee, recta vel curvate, normaliter quadri- 
loculares, loculis amplis vel angustis, quorum duo interpositi 
vix non semper rectangulari-tetragoni, extimi duo subconici. 
In quibusdam speciebus loculi omnes ocellulati apparent, ocellis 
rhombeis, subrotundis yel ellipticis, in singulis loculis ut pluri- 
mum singulis. Thallus varius, in corticolis hypophleodes, 
Hypothallus modo obsoletus, modo distinctus, ater. 
Cohors I. 
Epithecio brevi vel dimidiato ; paraphysibus nullis vel obsoletis; 
ascis elongato-clavatis, ventricosis, inflatis, octosporis; sporis 
in duplicem triplamve seriem intra ascos distributis, tumi- 
dulis, ellipsoideis obovatisve, eximie bombyciformibus, gran- 
diusculis, quadrilocularibus, loculis binis intermediis rect- 
angulari-tetragonis, extimis duobus ad formam coni, quorum 
infimus vix non semper minor. (Species omnes saxicole, 
hermaphrodite.)
