We are indebted to S. Sun hede for his skill with many photographs, and both he, N. Hallenberg and K. Hjortstam have contributed with numerous collections. K. Hauer slev, Denmark, has very generously sent us many interesting specimens from his rich Danish collections, while Dr. E. Parmasto,Tartu, USSR, has sent types ofhis many Siberian species. Dr. L. Weresub, Ottawa, Canada, has in many ways contributed to the flora especially what concerns ques tions on nomenclature for which we thank her most sincerely. Above all we are deeply indebted to Dr. A. Strid, Umea, who has been coauthor withJohnErikssonon the manuscript on Hyphoderma. Mrs. M. Espeland, Oslo, has suggested improvements in the English text. TheResearchCoun cil of Norway has borrowed us money enablingus to publish this volume while the Research Council of Sweden has contributed to the cost ofthe illustrations. Further)we are much obliged to the scientific staff of the herbariaof Uppsala, Stockholm, Helsinki, Leiden and Kew, who have sent us type material for comparison.

ColI. and photo S. Sunhede 3600 (onPopulus, Czechoslovakia). 289 Auriculariopsis Auriculariopsis Maire Bull. Soc. mycol. France 18 (suppl.) p. 102, 1902. Fruitbody pileate, cupulate (discomycete-like), upperside felted, the lower hymenial side radially folded, when wet soft and gelatinous, when dried more or less folded together; hyphal texture duplex, consisting of an upper layerof thickwalled, unbranched hair hyphae and a hymenial layer ofgelatinous, densely united hyphae with clamps; no cystidia; ba sidia subclavate, in a dense palisade (Phlebia-like); spores allantoid, smooth, thinwalled, non-amyloid. Genotypus:Auriculariopsis ampla (Lev.) Maire. Remarks. The genus issegregatedfrom Cytidia, in which it was as a rule placed earlier. It is, however, very well distinguishedfrom Cytidia, which has a catahymenium ofdendrohyphidia and large basidia, while inAuri.. culariopsis the hymenium is a normal phlebioid one. Its closest relatives seem to be Cytidiella and Merulius and its place should therefore be in Corticiaceae in the wide circumscription given the family here, not in CypheUaceae, to which it is often referred. The relations to Cytidiella are very close, but as this genus lacks the duplex structure, it may be cor rect to keep them apart. 290 r---------< (mm Fig. 112.

Fruitbody pileate, cupulate or bellshaped, ab. 1 cm in diam., directed downwards, with white felted upperside, when fresh and wet with pale ochraceous to light brown (cinnamon) hymenium, folded in radial ridges, margin even, slightly revolved, finely fibrillose; when dried the fruitbody is shrunk and more or less folded together. Hyphal texture duplex, forming two distinct layers: I} upper layer form ing the pubescence or surface felt, consisting ofthickwalled, twisted, non gelatinous hair hyphae with practically no septa and clamps 2} lower, tramallayerofgelatinous, richly branched but mainly parallel hyphae with numerous clamps and anastomoses. The hair hyphae of the upper layer are formed as a transformation ofgelatinous hyphae from the tramallayer or from much branched, irregularly twisted intermediate hyphae. From onetransitional hyphae several hair hyphae may branch off. The diameter ofthe hair hyphae is mostly 2-3 pm; the gelatinous hyphae are wider and may swell to 7 or even lapm. Cystidia none. Basidia subclavate, 25 - 30 x 4 - 4,5 pm, with 4 sterigmata and basal clamp. la (- Spores allantoid, smooth, thinwalled, non-amyloid, 7,5 - 12) x 2,5 (- 3) pm. Habitat. On dry branches, mainly ofSalix and Populus. Distribution. It is widely distributed in S. and C. Europe and is locally common, e.g. in the sand dune areas ofHolland. In N. Europe it is hi therto found only in Denmark, where it is collected inJylland, Fyn, Lolland, and Bornholm (FriesiaIII p. 67, where it is well described and figured by F.H. Moller) and in Sjelland (by Hauerslev). The Danish col lections were made onPopulus, both onP. tremula and on introduced foreign species. 292 u Fig. 113.

It is, however, not cogeneric with the type ofCytidia. In the Uppsala herbarium there is an authentic specimen of Thelephora floccu lenta Fr. from Femsj6 in Sweden. The label is written with Fries's own hand. Lundell has put alabel into the envelope and states that therewas nothing left ofthe fungus already in 1944. There are, however, two pieces ofwood and on one ofthem there is a small piece ofa corticioid fungus. It is determinable and is Corticium evolvens (Fr.) The epithet flocculenta cannot therefore be used for the fungus described here. Auriculariopsisampla has often been referred to Cyphellaceae but its closest relatives are certainly to be found among the phlebioid corti cioid fungi.
