New lichenicolous fungi found on the NLF meeting in Norway 1993 VAGN ALSTRUP Alstrup, V. L997: New lichenicolous fungi found on the NLF meeting in Norway 1993. Graphis Scripta 8:25-29. Stockholm. ISSN 0901-7593. Cephalosporiopsis epiparasitaster sp. nov. , Cercidospora cladoniicola sp. nov., Merismatium cladoniicola sp. nov. , Phoma lobariicola sp. nov. and Scutula Iobariicola sp. nov. are described, and Erdococcus verrucosporus is reported from Norway. Vagn Alstrup, Department of Plant Ecology, University of Copenhagen, O. Farimngsgade 2D, DK-1353 Copenhagen K, Denmark. During the NlF-excursion in Nord-Trsndelag, Norway in July t993, I especially looked for lichenicolous fungi. The majority of these collections were reported by Holien & Tonsberg (1994), but some undescribed species were omitted and are now reported. Cephalosporiopsis epiparasitaster Alstrup sp. nov. Hyphomyces in Chaenothecopsi parasitastro parasiticus, tomento niveo eam induens. Mycelium immersum vel superficiale, e hyphis hyalinis circiter 2.5-3 pm crassis constitufum. Conidiophora phialidica, alba, ramificata vel simplicia, plerumque recta, fragilia, circiter 15- 55 pm alta, ?d bases circiter 3 Fffi, ad apices 0.7 -I Frm crassa, collarellis parvis terminata, si longa septis parum distinctis, inter se circiter 10-15 pm distantibus divisa. Conidia singula, ex apicibus apertis phialidum formata, subcylindrica, ad apices rotundata, basibus non truncatis, nullis septis visis, hyalina, 8-9 x 2 pm magna. - Figure 1. Type: Norway, Nord-Trondelag, Grong, c. 1 km E of Grong centre, small brook ravine NE of hill 185, UTM: 33W UM 7252, map t823 IV, alt. 100-160 m, old spruce forest, on Chaenothecopsis parasitaster, 26 July 1993, V. Alstrup (C, holotype). Hyphomycete, parasitic on Chaenothecopsis parasitaster, giving it a snow-white, woolly appearance. Mycelium immersed to superficial, of hyaline hyphae c.2.5-3 pm thick. Conidiophores phialidic, white, branched or unbranched, mostly straight, brittle, c. 15-55 pm high, c. 3 pm broad at base, 0.7-t pm at top, ending in a small collarette, if long indistinctly septate with c. 10-15 pm distance between septa. Conidia single, formed from the open ends of the phialides, almost cylindrical with rounded ends, not truncate at base, septa not seen, hyaline, 8-9 x 2 pm. Cephalosporiopsis epiparasitaster is especially frequent on the head of Chaenothecopsis parasitaster, giving the infected heads a white, woolly look, but it is also found dispersed on the stalks. Chaenothecopsis parasitaster itself is parasitic on squamules of Cladonia digitata. Cephalosporiopsis is being revised by D. Bradford and G. J. Samuel, who include three fungicolous species placed in C)tlindrocarpon by Deighton & Pirozynski (1972) in Cephalosporiopsis. Two species of CJtlindrocarpon is
