SUMMARY OF CURRENT RESEARCHES RELATING TO 
Lichens in the Herb. Gunnerus. — Bernt Lynge ( Kgle . Norske 
Vidensk. Selsk. Skr ., 1920, N. 3, 12 pp.). Gunnerus was bishop in 
Trondhjem from 1758 to 1773. His diocese was large, and as he 
travelled from one place to another he collected natural history and 
other specimens ; lichens form a small part of his’ herbarium and are 
listed in the order of their collection. Lynge has gone over the plants 
and publishes the bishop’s names and numbers with his own notes and 
modern determinations. A. L. S. 
Lichens of Pas-du-Calais. — Bouly de Lesdain {Bull. Soc. Bot. 
Fr ., 1920, 67 , 217-28). The author collected during several months 
on the dunes and in various inland districts. The species listed are 
often accompanied by biological notes. Lesdain gives, for instance, an 
account of Ramalina farinacea, which grew out from R. calicaris, probably 
due to very close association from an early stage of development ; he has 
noted similar cases in Gladonia. A list is given of species found on 
unusual substrata, such as bones, iron, leather, etc. A. L. S. 
Lichens from the Neighbourhood of Versailles. — Bouly de 
Lesdain {Bull. Soc. Bot. Fr ., 1921, 68, 16-24). The list forms the 
final supplement to lichens already published from Versailles : some are 
new to the district ; others had already been recorded. The author 
adds a list of microfungi which he found during his search for lichens. 
A.L. S. 
New Lichens. IX.— A. Zahlbruckner {Ann. Mycol ., 1921, 19, 
224-42). The author describes twenty-five new species of lichens 
belonging to many different genera and from widely different localities 
— from Mexico, West Indies, East and West Africa, etc. One of the 
most notable is Galoplaca teloschistoides , with an upright branching 
thallus in tufts up to 40 mm. high. As the thallus has no cortex 
Zahlbruckner classifies it under Caloplaca rather than Teloschistes.

Lichenological Notes. XVIII. — Bouly de Lesdain {Bull. Soc. 
Bot. Fr., 1921, 68, 203-7). The paper consists mostly of diagnoses of 
new species from various countries — Switzerland, Portugal, Italy, 
N. America. One new genus has been determined, Henrica, distin- 
guished by the rosulate thallus which in age forms podetia about 
2' 5 mm. high. The apothecia bear large brown muriform spores.

Lichens from the Gj0a Expedition.— Bernt Lynge ( Vid.-Selek . 
Skr., 1921, 1 , Mat. Nature. Kl., N. 15, 7 pp.). A small collection was 
made during the above expedition to the North-West Passage, by 
Henrik Adolf Lindstrom. The lichens were found mostly at Gj0a 
Harbour and at Herschel Island. One new Lecidea was determined. 
A.L.S. 
Swedish Xarithorise. — G. Einar du Rietz {Svensk. Bot. Tidsk., 
1921, 15 , 181-91). The author notes that Th. Fries included three 
species in his “ Lichenographia Scandinavica ” ; he himself adds several 
species to the flora. Various localities are given for Xanthoria fallax.
