92 RESEARCHES ON FUNGI 



scorodonius (+), M. oreades (+), Agaricus ostreatus 

 (+), A. campestris, Hypholoma fasciculare (+), 

 Coprinus atramentarius (connexions everywhere 

 splendidly visible). In all these fungi all the 

 tissues of the fruit-bodies, chiefly young ones, were 

 investigated and the connexions were found every- 

 where. 

 V. Polyporaceae : Boletus versipellis (connexions every- 

 where can be easily seen), Polyporus fuscidulus ( +), 

 Polyporus perennis (+), and Daedalea Poetschii 

 (+), (hymenial layer not investigated, in other 

 parts the connexions were rather difficult to 

 observe), Merulius lacrymans (mycelium only 

 investigated). 



VI. Hydnaceae : Hydnum compactum (+). 

 VII. Clavariaceae : Corallium pratense ( -f). 

 VIII. Tremellineae : Calocera viscosa (+), Tremella undulata 

 (connexions everywhere can easily be seen). 



IX. Hymenogastreae : Hydnangium carneum (connexions 

 everywhere present). 

 X. Lycoperdaceae : Bovista nuciformis ( + ), Scleroderma 

 vulgare (+). 



XI. Nidularieae : Crucibulum vulgare ( + ). 



XII. Saccharomycetes : Saccharomyces cerevisiae (the young 

 cells remain for some time connected with the 

 mother-cells by a thread of protoplasm). 

 XIII. Perisporiaceae : Eurotium herbariorum, Aspergillus 

 niger, Penicillium glaucum. In all these three 

 fungi there are connexions between all the cells 

 of the mycelium from the finest branches right 

 up to the conidia. 

 XIV. Hypocreaceae : Claviceps purpurea. Only sclerotia 

 investigated. Connexions somewhat difficult to 

 find, best seen in preparations kept in an alcoholic 

 sublimate solution for 24 hours, then washed, and 

 then treated with chlor-zinc iodine.
