Pseudocypliellaria. 183 



Thallus foliaceus, adscendens aut raro fere adpressus, su- 



perne et inferne strato corticali parenchymatico obductus, inferne 



rhizinis et pseudocyphellis instructus. Stratum corticale suxoeriiis 



ex hyphis verticaHbus vel subverticahbus formatum, series cellu- 



larum plures irregulariter horizontales continens, loculis majusculis 



aut in seriebus summis minoribus, parietibus (membranis) com- 



parate sat tenuibus aut leviter modiceve incrassatis. Stratum 



medullare stuppeum, hyphis implexis, crassitudine mediocribus 



(circ. 0,0 4 0,0 3 milhm. crassis), membranis tenuibus, kimine 



comparate sat lato. Stratum corticale inferius e seriebus celki- 



larum paucis formatum. Bhizinae ex hyphis constantes par- 



tim subsohtariis, partim fasciculatis et laxe cohaerentibus, pro 



parte etiam connatis, apice hberis penicillatisque. Pseudocypliellae 



maculae- vel verrucaeformes aut leviter urceolatae, fundo decor- 



ticato (formato e strato medullari crebrius contexto), soredia 



parce formantes. Gonidia palmellacea (protococcoidea aut forsan 



etiam pleurococcoidea) et flavovirescentia, aut nostocacea (Bornet, 



Rech. Gon. Lich. p. 36) et ceJluHs caeruleovirescentibus vel glau- 



cescentibus monihformi-concatenatis, filamentis ad instar Poly- 



cocci glomeruloso-intricatis, in zona infra stratum corticale su- 



perius thaUi disposita. Apothecia marginaha aut supra thaUum 



sparsa, peltata. Excipulum strato corticali pseudo-parenchy- 



matico, crasso (ceUuhs fere sicut in strato corticaU thaUi), strato 



medullari ex hyphis leptodermaticis contexto, zonam gonidialem 



sokmi infra stratum corticale continente (in sect. Parmosticta 



Nyl. et Parmostictina Nyl.) aut gonidiis omnino destituto (in 



sect. Lecidosticta Wainio et Lecidostictina Wainio). Hy- 



pothecium paUidum aut albidum. Paraphyses sat arcte cohae- 



rentes, gelatinam haud abundantem (in KHO sat laxam) percur- 



rentes. Sporae 8:nae aut abortu pauciores, fusiformes aut fusi- 



formi-oblongae, 1 5-septatae, fuscescentes aut decolores. Con- 



ceptacula pycnoconidiorum thaUo immersa, paUida (aut kitea al- 



bidave), minute parenchymatica. Sterigmata ramosa aut subsim- 



phcia, constricte articulata, articuhs numerosis, brevibus. Pyc- 



noconidia oblongo-cyhndrica [aut apicibus levissime incrassatis?], 



brevia, recta, tenuia.
