T. Hallingback has made the macrophotos and some ofthe SEM-photos, sterile cultures and contributed to the collecting in the field for which we are very grateful. As before, R. Winther, Oslo, has suggested im provements in the English text while professor A. Fridh, University of Goteborg, has corrected the Latin diagnoses.

Fruitbody resupinate, adnate, smooth or under a lens more orless odontioid,offragileconsistency in the dry state; hyphae wide, short celled, branched at right angles, without clamps, basal hyphae with thickened (double) walls; cystidia (pseudocystidia) more or less pro jecting, at first thin-walled, not septate, when fully-developed septate with thickened walls; basidia sub-cylindrical - constricted - sub urniform, often with linear repetition, even several times renewed;spores oblong - ellipsoid, thin-walled, smooth,non-amyloid, non-cyanophilous. Type species: Candelabrochaete africana Boid. Remarks. The genus reminds ofPhanerochaete by the lack of clamps, nature of spores, and in the presence of cystidia, but well distinguished by the short-celled hyphae and the shape and linear repetition ofthe basidia. Together with Repetobasidium and Repetobasidiellumthey are the only genera known with renewed repetition. Phanerochaete septo cystidia (Burt) Erikss. & Ryv. reminds very much of Candelabrochaete in the septation of the cystidia and to some degree also in the nature of the basal hyphae but in this species the basidia are narrowly clavate and packed together in a palisade as they normallyareinPhanerochaete, nor does linear repetition occur. Hitherto two species are referred to Candelabrochaete, the type species and C. langloisii (Pat.) Boid. Candelabrochaete africana Boid., loc. cit. Fig. 535-38 Fruitbody resupinate,adnate,effuse,of moderatesize and almost smooth but becominggranularor finely odontioid (lens), when dried fragile, margin not especially differentiated. Hyphal systemmonomitic; all hyphae without clamps, short-celled, branched at more or less right angles, non-cyanophilous, subbasidial hyphae thin-walled, 3 -4 /.lIDwide; basal hyphae 8 - 15 /.lm wide, with thickened to very thick walls. In young, empty hyphae the dolipore apparatus is as a rule easily visible. In old tissues there is a resinous, yellow-brown encrustation, which may beabundant, giving the whole fruitbody a brown colour. 1054 Cystidia 70 - 140 x 8 - 12J.l.m, as a rule arising fromthe basal hYI?h~e (pseudocystidia), septate, finally thick-walled, smooth,young ~ystl~ba thin-walled, not septate, with homogenous contents, thus lookmglIke gloeocystidia of e.g. Hyphoderma.

Candelabrochaete~fricana. a) partoffruitbody b) basidia, two repeating ones c) spores. - Type specimen. 1055 CandeIabrochaete Basidia 12 - 18 x 3 - 4.5 pm, sub-cylindrical, as a rule apically widened, more or lessconstricted in the middle(suburniform), with 4 sterigmata and without basal clamps.Linear repetition frequent (esp. in the Nor wegian materialbut seen also in the type) and results in structureswhich could be interpreted as apical growth of basidia with several sets of sterigmata, but the repetition is evidently the same as in Repetobasi dium, only more difficult to observe as there are no clamps present. Spores 4.2 - 6 (- 7) x 2 - 3 (-4) pm, sub-cylindrical to ellipsoid, thin walled,smooth, non-amyloid, non-cyanophilous. Habitat and distribution. On decayed wood of coniferous trees. In N. Europe found only once, viz. in Norway. Hedmark, Folldal, Holen near Grimsa, on wood ofPinus sylvestris. 1979-08-25. Ryvarden No. 17652/B. Remarks. The Norwegian material agrees with the type of C. africana and is definitely a Candelabrochaete. There are, however, some differ ences, making it questionable if they really are conspecific. The basidia of the type are shorter, the spores narrower, and the basal hyphaewider. Besides there is a difference in the shape of the cystidia, which in the Norwegian material are composed of barrel-shaped cells, while in the type the walls of the cystidia are more parallel and also more clearly two-layered. We have further studied one specimen of Odontia modesta Rick (illegitimate name, the nomenclatural type was not indicated in the protologue) from Brazil (Rick 17630) which also clearly belongs to C. africana s.l. It agrees more with the Norwegian material, esp. in the shape ofthe spores, but the fruitbody is young and the majorityof the numerous cystidia are still in the thin-walled, non-septate state. There are finally two specimens collected by Ryvarden in Africa, one from Malawi (Ryv. 11300/F) and one from Kenya (Ryv. 9056). These two collections differ fromthe others in several respects. The Malawi speci men is in the prime of its development while the Kenya spec. is older, a large specimen, but they are no doubt conspecific. They differ from C. africana in the shape of the hymenium, which is more distinctly odont oid, the hyphae are narrower and - as are also the cystidia - more thin-walled. The subicular tissue becomes filled with some resinous, yellow-brown matter, which gives the fruitbody a buff to ferruginous colour. The cystidia are fewer, less projecting. The shape and size ofthe spores are about the same as in the Norwegian material. Thus,it seems possible, from the material studied, to separate C. africana s.l. in three taxa: the type, the Norwegian-S. American material, and those from Kenya and Malawi. 1056
