tum can infect the same again but not the Myriophyllum alterni- 

 florum. 



The hyphae of the hymenium of Sebacina caesia (Pers.) Tui. 

 are hy sympodial growth perpetually forming new basidia and 

 thereby working out a gradual thickening of the crust. By Sebacina 

 incrustans (Pers.) Tul. the same was found, but here orvXy 3 basidia 

 were united to a sympodium. Galactinia saniosa (Schrad.) Sacc. was 

 found near Aarhus; the specimens had a diameter of 3 cm and 

 contained a bright prussian-blue milk. Stictis Arctostaphyli Ferd. & 

 Wg. (Dec. 1907) is indentic with Coccomyces quadratus (Schm. & Kze.) 

 Karst, var. Arctostaphyli Rheni nom. nud. and with Naemacyclus 

 Senegalensis Rehm (1908). Gnomonia conformis (Berk. & Br.) Ferd. 

 & Wg. is identic with Sphaeria conformis Berk. & Br. and with 

 Massarina alnicola (Cooke & Massee) Berl. Diplodina Junci Ouds. is 

 identic with Diplodina juncicola (Rostrup; Lind. There is given a 

 list of 33 species of fungi, new to the Danish flora, and 5 new spec. 

 are described in Latin and deliniated viz: 



Barya lichenophila ad thallum Cladoniae. Jutland. 



Fenestella subvestita ad ramos siccos corticatos Alni glutinosae 

 prope Hafniam. 



Ophiobolus Rostrupii ad folia viva Brunellae. Unalaska. 



Parmularia Stimatopteridis ad folia viva Dryopteridis patentis, 

 Stimatopteridis alloeopterae, Carrii, caudatae, ichtyosmae, longicaii 

 datae and rotundatae from several South American localities. 



Pleospora tessellata ad ramulos siccos corticatos Zygophyllace-

Sur les thalles de Mucor sphaerosporus Hagem., feutres en 

 croüte ä la surface des vieilles cultures, particulierement sur pomme 

 de terre, on distingue des boules jaunätres de 300 ä 450 ,u, les 

 unes immergees, les autres saillantes. Le centre est occupe par une 

 volumineuse concretion d'oxalate de calcium; le reste est forme d'un 

 peloton de filaments ramifies dont tout le protoplasme est enferme 

 dans des chlamydospores. Gueguen compare ces nodules aux scle- 

 rotes des Champignons superieurs et des Myxomycetes.

Juel, O., On Taphrina Species on Betida. (Svensk Bot. Tidss. 

 p. 183—191. The text is in Swedish with a German summary, 

 and with 3 pl. containing 9 fig. 1909.) 



Ten species of Taphrina (including Exoascus) on Betida are 

 known: Taphrina nana Johans. is found on Betula nana only where 

 it forms small brushes and produces mycelium in the parenchyms 

 of leaves. T. alpina Johans. is without this mycelium and forms asci 

 on the underside of the leaves only ; it is to be found on B. nana and 

 verrucosa (hosp. nov.). T. betulae (Fuck.) Johans. and var. auctumnalis 

 Sadeb. both form stains on the leaves of B. pubescens and verrucosa ; 

 the stains of the principal spec. are yellowish green, and the stains 

 of the variety are reddish. T. Willeana Svendsen has larger asci, 

 and is to be found on B. nana X odorata only. T. turgida Sadeb. 

 on the contrary produces brushes on B. verrucosa, and T. betulina 

 Rostrup on B. pubescens. All the above six species have there asci 

 on a stalk-shaped cell, the following 4 have no such cell. T. carnea
