Obs. Mycoporum ptelaeodes var. majusculum Nyl., Obs. 

 Lich. Pyr. (Fl. 1873) p. 41, Lich. Pyr. Orient. (1891) p. 68, Hue 

 Addend. II (1888) p. 312, Minks Lich. Cyrtid. (1891) p. 7, his 

 verbis descripta est: „(huc Anzi Langob. n. 470 b) sporae 3 — 5- 

 septatae, longit. 0.oi6 — 23, crassit. O.oos — 10 millim.", pr. p. etiam 

 ad C. majorem spectat, sed specimen orig. e Massane in Pyrenaeis 

 ad earn non pertinet, apotheciis minoribus, saepe aggregatis con- 

 fluentibusque ab ea differens, et var. est Cyrtidulae ptelaeodis. 



4. Cyrtopsis Vain. 



Ad fungos pertinens. Mycelium gonidiis destitutum, 

 hyphis fuscescentibus. Apothecia simplicia. Perithecium 

 fuscum, tenue, collapsum sporas evacuans. Paraphyses in 

 gelatinam diffluxae. Sporae demum dilute obscuratae, 3-septa- 

 tae. Nucleus jodo saepe reagens. Corticolae. 



1. C. fumosa Vain. (n. sp.). 



Apothecia crebra, simplicia, verrucas formantia hemi- 

 sphaericas, O.ho — O.070 mm latas, nigricantes. Perithecium 

 fusco-nigrum, dimidiatum, nudum, hyphis fuscis e basi excre- 

 scentibus abundantibus. Paraphyses in gelatinam diffluxae. 

 Sporae decolores, demum dilutissime subfumosae, oblongae 

 aut subfusiformes, apicibus obtusis rotundatisve, 3-septatae, 

 long. O.013 — O.016, crass. O.005 — O.ooe mm. Thallus bene evo- 

 lutus, nigricans. 



Distr. Ad corticem Ribis rubrae et nigrae ad Rapa- 



ranta in Lapua in Ostrobotnia austr. (V. Rasanen).

 crebris, fumoso-nigricantibus aut fumoso-fuscescentibus, crebre 

 constricte articulatis, cellulis subglobosis, O.ooe — O.005 mm crassis, 

 leptodermaticis, parcius etiam hyphis cylindricis O.003 mm crassis 

 intermixtis. Passim parce in thallo etiam observantur algae 

 pleurococcaceae, simplices globosaeque, diam. O.006 — O.012 mm, 

 aut glomerulosae, membrana modice incrassata. Perithecium 

 plectenparenchymaticum, cellulis leptodermaticis, O.005 — O.006 mm
