468 SUMMARY OF CURRENT RESEARCHES RELATING TO 



rocks as the country becomes more settled, and fires are less frequent. 

 Another note he makes is that in areas that are poor as regards the 

 number of lichens to be found in them, the rarer plants are altogether 

 wanting, these being found in neighbourhoods with a richer flora. He 

 found a large number of species of Calicium, a genus that was once 

 thought to be peculiar to the Atlantic region ; his opinion is that the 

 Calicium follows the conifers regardless of slight climatic changes. He 

 concludes with a systematic list of the genera and species of the region. 

 There are a few species new to science or new to North America. 



M. H. Olivier * gives a further account of rocks bearing lichens col- 

 lected by the late T)r. Goulard in the Pyrenees-Orientales. He gives 

 detailed notes of some of the species of Dirina, Bacidia, Biatorella, and 

 Lecidea. 



E. Monguillon f continues his list of lichens collected in the depart- 

 ments of the Sarthe. The lists are arranged in the form of a key to the 

 different species. He deals with the genera from Cladonia to Leptogium 

 — altogether 50 genera. He gives no authorities and no extended de- 

 scription of genera or species. 



A. Zahlbruckner J publishes his sixth list of the lichens of the 

 Netherlands. The new species are Lecidea Baumgartneri found on 

 gneiss and Thelocarpon Strasseri on pine wood. The author has appended 

 critical notes to many of the species described. 



Servian Fungus Flora.§ — A first contribution to the fungus flora 

 of Servia is published by N. Eanojevie. Most of the specimens he col- 

 lected himself, and many of the parasitic forms he records from new 

 hosts. With the exception of the Peronosporeaa the list includes as yet 

 only members of the Basidiomycetes. 



Spanish Fungi. || — D. B. Lazaro has published a short list of fungi 

 new to Spain. The writer has described two new species of Dictyolus, a 

 genus formerly included under Cantlierellus, and one new species of 

 Scleroderma very near to vulgare, S. hemisphsericum, so called from the 

 shape of the sporiferous part of the fungus. 



Fungi from Java.1T — 0. Penzig and P. A. Saccardo publish a third 

 series of Javanese fungi. They nearly all belong to two groups, the 

 Ascomycetes and the Deuteromycetes. More than 100 of the species are 

 new. There are 4 new genera of Discomycetes, Arensea with 2 species 

 is near to Pirottsea, Davincia also has 2 species, the ascospores aie 2— 

 many septate, otherwise the genus resembles Cyathicula. Delpontia is 

 a new genus of Stictidiacea?; the spores are hyaline, multi-septate, and 

 muriform. Moutoniella belongs to the Phacidiaceae ; it is near to Stegia 

 but with filiform spores. In the Pyrenomycetes the authors describe 

 two new genera. Binia, a member of the Sphseriaceas, has elliptical one- 

 celled colourless spores, the ostiole of the perithicium is large and 

 stellate. Fleischeria forms a stroma on living branches, the spores are 

 filiform and colourless; it is one of the Hypocreaceaa. The authors
