Thallus in exsicc. Wright partim hypophleodes, partim et saepius epiphleodes, glauco 

 albidus \el cinerescens, tenuissimus, continuas, peripheriam versus lœvigatus et in centro 

 rugulosus, hinc Inde hypothallo nigro limitatus et hydrate kalico immutatus. Cortex 10-15 a 

 latus et corpusculis atratis obnubilatus ; in eo hyphae intricatae, articulatœ, ramosae et stricte 

 coahtae , in partibus hypophleodibus, cortex deficiens et hyphae gonidiales longis corticis 

 arboris zonis obtectœ. Gonidia viridia, protococcoidea, 5-10 [x lata, membrana tenui, stratum 

 continuum vel glomerulos sub cortice formantia. Hyphœ medullares paucœ in thallo, 

 numerosiores sub apothecio et inter has posteriores aliquot oxalatis calcici magni cristalli. 

 Apothecîa 0,2-0,5 mill. lata, supra thallum paulum elevata, dispersa et hinc inde contigua, 

 rotunda, in basi parum constricta, perithecio atrato, margine integro et discum parum 

 superante atque disco violaceo fusco, piano vel raro convexo atque nudo ornata. Peri- 

 thecium atratum, hydrate kalico violaceum, lateraliter 70 et subtus 50-60 u. crassum, ex 

 hyphis fastigiatis, ramosis ramis anastomosantibus reteque efficientibus constans. Gonidia 

 interdum inter perithecii hyphas, vulgo sub hypothecio, perithecio basali sœpe déficiente, 

 vigentia. Hypothecium incoloratum, lateraliter 10-20 et subtus 30-40 jj. crassum; ejus 

 hyphae horizontales et oblongo articulatae, in centro intricatae ac sphœroideo articulatœ, 

 lumine 2-4 y- lato, ac parum stricte coalitœ. Paraphyses hyalinae, sursum ati-atœ et hydrate 

 kalico violaceae, 60-100 p. altœ, 3-4, et in apice 5-6 [x crassae, rectœ et flexuosae, arcte 

 cohaerentes, articulatae articulis parum longis, dissepimentis brevibus lumineque 1, et in 

 apice 3 \j. lato, non raro ante apicem furcatae et interdum sub cellula ultima, aliam 

 cellulam 3 [x latam praebentes atque iodo caeruleœ. Thecœ 40-90 \j. longœ et 10-25 ix latae, 

 in apice incrassatœ et in basi caudatœ ; sporœ octonae, hyalinae, distichae, simplices et 

 polocœlœ, cavernulis 3 [x metientibus et tubulo angustissimo junctis, 12-15 [x longae et 

 6-8 [x lalae. 



Species corticola, Americœ propria et vigens in septentrionali (Florida, Texas ac Louisiana) 

 atque in meridionali (ins. Cuba et Brasilia).
