Thalliis foliaceus aut squamosus, monophyllus aut polyphyl- 



lus, superne et distincte etiam inferne strato corticaH obductus, 



superne glaber, inferne rhizinis caeruleo-nigricantibus albidisve 



aut hypothallo tomentoso (eodem colore) instructus. Stratum cor- 



ticale superius ex hyphis longitudinahbus ^) parenchymatice sep- 



tatis conglutinatis formatum, series paucas pluresve irregulariter 



horizontales continens, locuhs latitudine mediocribus (diametrum 



hypharum strati medullaris leviter superantibus aut fere aequan- 



tibus), parietibus tenuibus. Stratum medullare hyphis circ. 0,oo4 



0,0 3 milHm. crassis, leptodermaticis, increbre aut crebre sep- 



tatis, longitudinahbus, sat laxe aut sat crebre contextis, partim 



aut parte inferiore conglutinatis, quare hoc stratum sine Hmite in 



stratum corticale inferius transit. Stratum corticale inferius ex 



hyphis distincte longitudinaUbus, crebre aut sat crebre septatis, 



onglutinatis formatum, membranis tenuibus aut leviter incrassatis 



(in G. Gayana). Gonidia scytonemea (Bornet, 1. c), celMis 



caeruleo-virescentibus, in filamenta gyrosa brevia aut sat brevia 



concatenatis et heterocystis hyahnis intercalaribus instructa, vagina 



gelatinosa sat tenui induta, in zona infra stratum corticale supe- 



rius disposita. ApotJiecia in ipsa superficie thalK aut rarius (in 



G. Gayana) infra stratum corticale enantia, demum elevata, pel- 



tata basique bene constricta aut tota basi adnata, haud podicel- 



lata. Excipulum saltem parte exteriore grosse pseudoparenchy- 



maticum et ex hyphis radiantibus parenchymatice septatis forma- 



tum, gonidiis destitutum (strato medullari stuppeo nullo). Hypo- 



thecium pallidum aut obscuratum. Sporae 8:nae, oblongo- aut 



elHpsoideo-fusiformes aut elHpsoideae aut globosae, simpHces, de- 



colores. Conceptacula pycnoconidiorum verrucas thallo obductas 



formantia, intus albida. Sterigmata articulata, ceHuHs brevibus,
