of the usual cavity partially filled by asci and paraphyses. This condition suggests the situa- 

 tion in Penicillium or in the Plectascineae, except that here the asci arise at the base of the 

 ascocarp. The fungus therefore is placed in a new genus, Desmotascus, and the species is 

 named D. portoricensis. — H. C. Cowles. 



1313. TisDALE, W. B. Iris leaf spot caused by Didymellina iridis. Phytopath. 10: 148- 

 163. 6 fig. 1920. — The causal fungus, usuall}^ known in its conidial state as Heterosporium 

 gracile, is traced through its life cycle, and its taxonomy, morphology, and host relationships 

 are considered in detail. The removal of dead infected leaves in spring before new foliage 

 appeared controlled the disease. — F. R. Jones.

 zilian polypores.] Broteria: Ser. Bot. 18: 121-143. PI. 5-8. 1920. — The article contains a 

 key to the Brazilian genera of stipitate polypores, a discussion of 34 species of the genus 

 Amauroderma, and a key for separation of the species. Each species is given a brief techni- 

 cal description in addition to less formal observations. A. Gusmanianum, A. picipes, and 

 A. Mosselmanii are proposed as new. Photogravure plates illustrate the gross characters 

 of 11 species, or varieties. — E. B. Chamberlain.

 Hedwigia 61: 308-342. 1919.— Collections made in vicinity of Lake Narotsch, 55''N., 27°E. 

 First 12 pages devoted to physiographic, climatological, and plant geographic features of 

 the region with observations on the lichen vegetations of different substrata — soils, stones, 

 trees, etc. — The 204 species found are arranged in systematic order and aside from localities 

 there are brief notes on many species. Acarospora globosa (Koerb.) is described fully. — 

 Many species which usually are sterile were found fruiting abundantly. Six lichen parasites 

 are mentioned. A comparison with other lichen floras is included. — D. Reddick.
