HOLUBOVÁ-JECHOVÁ V. (1990): Zygosporium mycophilum (Vuill.) Sacc. in Czechoslovakia. Česká Mykologie 44(2): 106-108 (published: 22nd June, 1990)
abstract
Zygosporium mycophilum (Vuill.) Sacc. is described and illustrated from a decayed apple, rotten by Botrytis cinerea and various species of Penicillium, in Czechoslovakia. It seems that the species is not an obligate mycoparasite, but is obviously mycophilous, growing always among other microscopic fungi. Conidia were oval to ellipsoidal, hyaline, 5–8.5 × 4–6 µm, minutely verruculose. This collection is a first record from Czechoslovakia.

abstract
A new species Scytalidium multiseptatum isolated from cysts of Globodera rostochiensis Woll. (potato cyst nematode) collected in South Bohemia is described and illustrated. A morphological comparison with other species of this genus is added. The fungus appears to be a potential pathogenic invader in agricultural soils, potentially contributing to nematode suppression.

abstract
Sixty-eight species or varieties of lignicolous and other saprophytic Hyphomycetes belonging to 47 genera are recorded from the Isla de la Juventud (formerly Isla de Pinos). The majority of them are probably common species in subtropic or tropic regions, however, previously unreported from Cuba or adjacent islands in Caribbean area. Some infrequent or rare Hyphomycetes were also collected and 11 new species are described here.
HOLUBOVÁ-JECHOVÁ V. (1983): Studies on Hyphomycetes from Cuba I. Česká Mykologie 37(1): 12-18 (published: 1983)
abstract
Six hyphomycetes collected in Cuba are described and illustrated. New varieties — Acrodictys elaeidis var. cubensis, Catenularia cuneiformis var. minor and Chloridium reniforme var. minor — differ distinctly in the size of conidia and in some other characters from their type varieties of original species. Megalodochium inflatum and Spadicoides cubensis are described as new species. The known subtropical species Sporidesmium arengae is newly taxonomically classified as Brachysporiella arengae (Matsushima) Hol.-Jech.

HOLUBOVÁ-JECHOVÁ V. (1972): Craspedodidymum, new genus of pheilosporous Hyphomycetes. Česká Mykologie 26(2): 70-73 (published: 1972)
abstract
The new genus Craspedodidymum Hol.-Jech. and new species C. elatum Hol.-Jech. are described from rotten basal parts of the petioles of Phoenix canariensis hort. ex Chabaud. The fungus has dichotomously branched conidiophores and dark, non-septate, ellipsoid phialospores borne singly in an open collarette at the branch tips. The fungus differs from all previously described genera of phialosporous Hyphomycetes by its conidial morphology and branching pattern.
HOLUBOVÁ-JECHOVÁ V. (1971): Polyphenoloxidase enzymes from wood-inhabiting Hyphomycetes. Česká Mykologie 25(1): 23-32 (published: 28th January, 1971)
abstract
Oxidase tests were applied to 35 wood-inhabiting saprophytic Hyphomycetes to determine their ability to produce polyphenoloxidase enzymes. Most produced laccase, some tyrosinase, and a few peroxidase. The presence of these enzymes, especially tyrosinase, has taxonomic significance. This is the first report of such enzymes in Hyphomycetes.

abstract
Six variants of Cercospora beticola were isolated from the territory of Slovakia. According to the cultural properties on potato glucose agar medium they could be characterized as: dark grey, dark grayish-green, ash-grey, deep grayish-green, light grayish-green and white grayish-green. Inoculation of susceptible and resistant sugar beet cultivars showed a correlation between pigmentation intensity and aggressiveness, with darker variants being more virulent and sporulating more heavily.

abstract
Seventy taxa of dematiaceous Hyphomycetes belonging to 44 genera were collected in the Province Pinar del Rio, in the western part of Cuba. An attention was mainly given to the saprophytic microfungi colonizing dead wood and bark of different broad-leaved trees, palms and decaying herbaceous material. Twenty-three hyphomycetes are recorded here for the first time from the Cuban territory, seven taxa of them are described and illustrated as new for science: Corynesporopsis rionensis Hol.-Jech., Monodictys sessilis Hol.-Jech., Pithomyces sumiderensis Hol.-Jech., Pseudospiropes cubensis Hol.-Jech., Sporidesmium dissolvens Hol.-Jech., Mercado et Mena, Virgariella caribensis Hol.-Jech., as new species and Sporidesmium tropicale M. B. Ellis var. cubensis Hol.-Jech. as a new variety. Codinaea lunulospora Hewings et Crane is transferred to Dictyochaeta and Sporidesmium pseudolmediae Castañeda to Corynespora. One typical lignicolous ascomycete Nitschkia acanthostroma (Mont.) Nannfeldt is also added.

Belltrania rhombica O. Penzig and Circinotrichum papatpurae Hughes et Pirozynski are reported here from Cuba for the first time.

abstract
A new species of lignicolous Hyphomycetes, Hyphodiscosia europaea Hol.-Jech. et Borowska, collected on decaying wood and bark in Czechoslovakia and Poland is described and illustrated. Taxonomical investigations of the microfungi inhabiting bark and wood of decaying trunks and stumps in Czechoslovakia and Poland have revealed the presence of one undescribed species of dematiaceous Hyphomycetes which is classified here in Hyphodiscosia Lodha et Chandra Reddy. This genus was recently described (Lodha and Chandra Reddy 1974) as monotypic with H. jaipurensis Lodha et Chandra Reddy, growing on bark of dead wood collected near Jaipur in Rajasthan (India). The characteristic features of Hyphodiscosia are polyblastic conidiogenous cells producing subcylindrical, dorsiventral and 1-septate conidia with two lateral appendages (setulae), arising on the ventral side of the conidium. The species found differs from H. jaipurensis in having 1–3 septate conidia, with a seta on the apical end and a second one in the middle of the ventral side of the basal cell of the conidium. A further difference is in the conidiophores; their conidiogenous parts proliferate successively and sympodially and do not terminate in a swollen conidiogenous apex as in H. jaipurensis. These differences are sufficient to separate this fungus as a new species for which the name Hyphodiscosia europaea is proposed.
