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
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.

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.
GRISHKAN I., TEMINA M. (2023): Diversity of microfungal communities inside saxicolous lichens from Nahal Oren, Mount Carmel, Israel. [endolichenic fungi, lichen thallus, melanised fungi, microclimatic contrast, rock surface.] Czech Mycology 75(1): 15-34 (published: 28th March, 2023) Electronic supplement
abstract
In this study, we examined the endolichenic fungal communities of saxicolous lichens covering the rocks in the Nahal Oren valley, northern Israel. A total of 60 fungal species belonging to 35 genera were isolated from six lichen species collected in the summer and winter on the south-facing slope (SFS) and north-facing slope (NFS) of the valley. We verified that rocks serve as a possible source for the formation of endolichenic communities because communities colonising lichen thalli and the rock surface shared 39% of species and clustered together on the SFS. On the NFS, with a comparatively favourable microclimate, lichen thalli abundantly harboured typical soil fungi such as Clonostachys rosea and Fusarium spp. in winter and summer, respectively. At the same time, more severe environmental conditions on the SFS facilitated the prevalence of melanised fungi with thick-walled and multicellular spores irrespective of season. The lowest species richness and isolate densities of endolichenic communities were registered in the thalli of Collema cristatum. This decrease, especially expressed in the summer, was probably associated with the antifungal effect of substances produced by its cyanobiont, as well as with the heavy dehydration of thalli during the dry season.
