Fungi of North Caledonia and the Loyalty Islands. — E. M, Wake- 

 field (F. Sarasin and J. Roux, Berlin and Wiesbaden, Nova Galedonia, 

 H)2<», 89, 108). The author comments on the character of the fungus 

 flora ; it is on the whole of tropical type with an intermingling of 

 temperate forms, and " the affinities are with Malaya, Australia and 

 other Pacific islands." There are also relations with Central and South 

 America, as well as with tropical Africa. There is a numerous list of 

 genera and species. The fleshy Agarics were named by the late W. 

 Massee. A nun^ber of new species in ttie various groups are diagnosed. 

 Habitats are not given. A. L. S. 



Botrytis cinerea as Parasite of .^sculus parviflora Walt. — 

 Alfred Markowski {Beltr. Biol. Pff. {Cohn), 1U17, 13, ;)47-74, 5 

 figs., 2 pis.). The fungus attacked and destroyed the twigs and 

 branchlets of the trees. The author has proved that the trouble was 

 due to Botrytis cinerea. He made careful inoculations on ^scuhis 

 parvitiora, where the results were immediate, and also on JE. Hippo- 

 castaaum, where they were less visible, as the fungus in that tree seemed 

 to go deeper. The action of the fungus on the host tissues is described. 

 Markowski discusses the question of sclerotia formation by Botrytis 

 cinerea. He does not look on the fungal balls formed by the fungus as 

 true sclerotia, but as pseudo-sclerotia, and concludes that there is no 

 connexion between this funs^us and Sclerotinia. A. L. S.

Diagnoses of Fungi from " Spotted " Apples. — x^rthur S. Horne 

 {Joiirn. Bot., ll)2(i, 58, 23S-J:2). The author isolated from "spotted" 

 apples a considerable number of familiar fungi, Pyrenomycetes or 

 Basidiomycetes. In addition he determined a new species, F]eof:pora 

 pomorum, and a new genus of Spha3ropsidea3 near to Fhoma, but 

 distinguished by the number of ostioles formed in one pycnidium. He 

 has named it Polyopeus, and has described four species of the genus 

 with a number of varieties. A. L. S. 



Lichens. 



Lichen Systematic Studies: 1. The Lichen-Genus Rhabdopsora 

 Miill.-Arg.— A. Zahlbruckner {tiedwiyia, 1917, 59, 801-4 ; 1918,. 

 305-G, 1 fig.). The genus Rhabdopsora was doubtfully placed by 

 Zahlltruckner among Gyalectaceffi. He has now examined the lichen on 

 which it was based, and he concludes that it is a member of the 

 Pyrenidiaceas. A. Lorrain Smith. 



Verrucariacese of Central Europe. — H. Zschaoke {Hedwiyia, 1918^ 

 60, 1-9). The study of this family w^as made while the author was 

 interned in Switzerland. He collected round Davos, and w^as granted 

 permission to work at the Zixrich Technical School. He gives lists,, 

 with notes, etc., of the genera Staurothele and FoJyblastia, both well 

 represented in Switzerland. A. L. S.
