Tóth, S.: Some new microscopic fungi from Hungary
ANNALES HISTORICO-NATURALES MUSEI NATIONALIS HUNGARICI Tomus 52. PARS BOTANICA 1960. Some New Microscopic Fungi from Hungary By S. TÓTH, Budapest As set out below, I wish to discuss some microscopic fungi, considered as new for science. I have collected all of them myself, and they are all deposited in the Collection of the Botanical Department of the Hungarian Natural History Museum (Herbarium Mus. Nat. Hung., Budapest, Hungária). I am deeply obliged to Professor A. Chaves B a t i s t a, Director of the Mycological Institute of the University of Recife, for his kind transmittance to incorporate in this paper of a new genus and its generotype, based on material collected by me, and dedicated to my name. 1. Gnomonia fumanae Tóth n. sp. The perithecia are solitary, or occurring in twos or threes, globulous, when desiccated their bases cave in, of about 200—300 p diameter, more or less immersed into or below the bark ; their walls 20—30 fi thick, composed of 4—5 layers of 6—10 Li deep cells, of about identical sizes and diameters, not thickened, and of brown walls. Each perithecium has 1—1 cylindrical or rostelliform ostiolum, arising by its tapering end above the surface of the substratum, they are rigid, straight, or somewhat curved, about 45—55 [i thick basally ; their length vary, depending on the thickness of the substratum above the perithecium, from about the halfth to the threefold length of the diameter of the perithecium. The asci are clavate or fusiform-clavate, of rounded tips, wath a rather long 2>edicel (not always observable), their walls are not or hardly thickened on their apices, containing 8, or rarely 4, spores situated obliquely in tw r o layers, the parts containing the spores are (35—) 45—55x8—12 p. The spores are hyaline or cylindrical with somewhat acute tips, divided medially by a septum, not or but slightly constricted at this point, with 4 large drops within each, 15—20x2,8—3,2 p, with one short, blunt, triangular, hyaline appendage at each end. On the dry twigs of Fumana procumbens (Dun.) Gr. et Godr. Peritheciis solitariis, vel 2—3 simul gregariis, globulosis, basi siccitate excavis, cca. 200—300 p diam., in corticem vel sub corlicem plus-minus profunde immersis, pariete 20—30 [t. crasso, e 4—5 stratis cellularum cca. aeqalium, isodiametricarum, non incrassatarum, brunnearum, 6—10 p diam. composito ; ostiolo cylindraceorostellato, exserto, rigido, plus-minus inclinato, longitudine pro ratione altitudinis immersionis 0,5—3-plici diametri perithecii, subtus cca. 45—55 p crasso ; ascis clavatis, vel fusoideo-clavatis, pedicellatis, apice non, vel modice incrassatis, 8-, vel raro 4-sporis, p. sp. (35—) 45—55x6—12 p (fig. 1-a) sporis oblique biseriatis,
