in Nylandia. Karelia Ladogensis: Ad saxum graniticum 

 in Kotomaki et in latere rupis micaceo-schistosae loco 

 passim irrigato ad Lahentausta in Kirjavalahti (J. P. 

 Norrlin). 



Species est dubia, sporis decoloribus et perithecio latius 

 fuligineo a f. irrigua St. fissae differens. In speciminibus ad 

 Lahentausta lectis in apotheciis morbose evolutis etiam sporas 

 demum dilute fuscescentes observavi, at in specimine bene evo- 

 luto ad Tali lecto sporae sunt persistenter decolores. Nucleus 

 parce resinoso-guttulosus, jodo caerulescens, dein dilute subru- 

 bescens, metaplasmate ascorum rubescente. Paraphyses in gela- 

 tinam diffluxae. Periphyses long. circ. O.020, crass. O.002 — O.003 

 mm, increbre septatae, extus saepe leviter gelatinosae. Sporae 

 oblongae, apicibus rotundatis, murales, cellulis demum numero- 

 sissimis, seriebus transversis cellularum saepe 7 — 10, irregulari- 

 bus, membrana sat tenui. Gonidia thalli pleurococcoidea, globosa 

 ( — subglobosa), simplicia diam. O.010 — O.005 mm, parce 1-septata 

 ellipsoideaque. Gonidia hymenialia parce etiam 4- et 3-cellulosa, 

 transversim et longitudinaliter divisa.

 est species propria Sphaeromphale umbrina nominanda" sec. Arn. Lich. 

 Tirol XXV (1883) p. 361 et forsan ad St. inconversam (Nyl.) pertinet. 

 Specimen in herb. Nyl. sec. determ. ejus ad St. elegcntem pertinet. — 

 V. inconversa Nyl. sec. Zschacke Hedwigia 1919 p. 2 pertinet ad Sphae- 

 romphalem Hazslinszkyi Koerb. (Par. Lich. 4 Lief., 1863, p. 331), quae 

 autem sporis „vulgo dilute fuscidulis" descripta est.
