86 SUM .MARY OF GUERENT RESEARCHES RELATING TO 



Swiss Lichens. — I. (1. Lettau {Hedwigia, 1918, 60, x4-lo<s ; II., 



1919, 267-312). The lichens listed in this work were mainly collected 

 in 1912. They are arranged according to locality : from Via Mala, 

 Martigiiy, Sion, etc. Any new species found are to be published later. 

 Most of the lichens collected are sasicoloiis. A. L. 8. 



Contributions to the Lichen-flora of Lower Austria. — A. Zahl- 

 BRUCKNER {Verk.K. K. Zonl.-Bot. ties. Wien, 1917, 68, l-;55). The 

 list is fairly extensive and includes a number of new species. Diagnoses 

 are also given of species not previously described with sufficient care.

Llanberis Lichens and District. — J. A. Wheldon {Journ. Bot, 



1920, 58, ]1-15). The lichens recorded are mostly saxicolous, as the 

 author of the paper spent most of his time collecting on the mountains 

 above the tree zone. The species found are listed, and biological notes 

 with the localities of eacli species are appended. Wheldon discovered a 

 new species, Bilimhia canihrica, the diagnosis of which is given. The 

 author states that the list is by no means exhaustive. 



W. Watson {Journ. Bof., 1920, 58, 108-10) evidently collected 

 over a wider area. He has recorded a considerable number of lichens 

 additional to Wheldon's list. These comprise many corticolous species, 

 and a proportion of rare and unusual plants. A. L. S. 



New Bueliise.— J. Steiner {Oesterr. Bof. Zeitschr., 1919, Xo. 57, 

 141-8). The Lichens here described are from many different countries 

 — from Central Africa, South America, North Europe, etc. — showing the 

 wide distribution of the genus, A. L. S. 



'Lichenographic Notes.— J. Steiner (Oesterr. Bot. Zeitschr., 191S, 

 Nos. 8--9, 27<)-81)= The author here deals with a fascicle of lichens 

 collected in Portugal by L. Menyhart in 1890. They are almost exclu- 

 sively corticolous species on Arbutus l7nedo,Pistacia Lentiscus, Fhillyrea, 

 Quercus Ilex, Ptjrus Mains, Viburnum Tinus, etc. With the exception 

 of a few new species or forms, and a few that are peculiarly ]\Iediter- 

 rauean species, the collection belongs to the widespread European flora.

Contribution to the Knowledge of the Greek Flora : C. Lichenes. — 

 J. Steiner ( rv/r. K.K. Zool.-Bot. Ges. Wien. 1919, 70, 52-101). The 

 lichens were collected by members of the Vienna University Expedition 

 in 1911. There are a large number from various regions and on various 

 substrata. A number of new species are described, and as the most 

 ontstiinding of these Steiner indicates Stereocaulon Santorinense, which, 

 though allied to S. denuilatum, differs in the persistence and form of 

 the primary thallus on which are borne the apothecia; the podetia are 

 constantly sterile. A. L. S. 



Preparation for a Lichen-flora of Balmatia. — A. Zahlbruckner 

 {Oesterr. Bot. Zeitschr., 1919, 70, 1-18, 148-65, 287-53, 297-326). The 

 present series of papers deals with collections by Baumg;>i-tner and 

 others made in Dalmatia and on many of the islands. The series
