Hymenoscyphus subcarneus, mało znany miseczniak występujący na mszakach, zebrany w Białowieskim Parku Narodowym

The discomycete Hymenoscyphus subcarneuswas found to grow parasitic on the liverwort Cephalozia catenulatain the Białowieża National Park (Poland), and is described and illustrated from the fresh collection. Two characters, the ascus apical ring structure of the Calycinatype and the contents of the living paraphyses (multiguttulate by low-refractive vacuolar bodies), have not been reported previously. In addition, a dried collection on Pohlia gracilis from Switzerland, Grimsel area, was studied. The relationship, taxonomy and infraspecific variation of the fungus are discussed. A new genus, Roseodiscus, is established to accomodate this bryicolous fungus together with two very similar equiseticolous species, Hymenoscyphus rhodoleucusand H. equisetinus. The three species are macroscopically characterized in the fresh state by a pale rosaceous-lilaceous hymenium and a mostly slender, concolorous or whitish stipe. Roseodiscusresembles Hymenoscyphusin various respects, but sharply deviates in the apical ring type which appears to indicate a more close relationship with genera like Calycinaor Stamnaria. Rhizoscyphus ericaewhich forms a mycorrhiza with roots of Ericaceae, is compared with Roseodiscus. Based on vital observations of R. ericaethis species is believed to be congeneric with the type of Pezoloma, P. griseum.Hymenoscyphus subcarneuszostał zebrany jako pasożytujący na wątrobowcu Cephalozia catenulataw Białowieskim Parku Narodowym; został opisany i zilustrowany na podstawie świeżych okazów. Dwie, nieznane dotychczas cechy zostały opisane: worki z pierścieniem apikalnym typu Calycinaoraz charakterystyczna zawartość żywych parafiz. Ponadto studiowano również zielnikowe okazy Pohlia gracilisz Grimsel w Szwajcarii, na których odkryto nowy rodzaj Roseodiscus. Autorzy dyskutują wzajemne relacje i taksonomię tego grzyba z podobnymi gatunkami występującymi na pędach skrzypów Hymenoscyphus rhodoleucusi H. equisetinus. Rozpatrywane są też podobieństwa i różnice między Roseodiscusa bliskimi rodzajami jak Calycina, Stamnaria, Rhizoscyphus i Pezoloma

Liverworts to the rescue: an investigation of their efficacy as mycorrhizal inoculum for vascular plants.

Pezoloma ericae (D.J. Read) Baral, a widespread mycorrhizal fungus of plants in the Ericales, is known to form intracellular associations with several families of leafy liverworts (Schistochilaceae, Lepidoziaceae, Cephaloziaceae, Cephaloziellaceae) in vitro. The ecological significance of this link between vascular and non-vascular plants is unknown. Fungal symbionts were isolated from rhizoids of the leafy liverworts Cephalozia connivens (Dicks.) Lindb. and C. bicuspidata (L.) Dum. (Cephaloziaceae), as well as from the hair roots of two dominant ericoid mycorrhiza-forming species of European heathlands, Erica tetralix (L.) and Calluna vulgaris (L.). Using pure cultures of P. ericae, we resynthesized liverwort–fungus associations to use colonized liverworts as inoculum which was applied to substrates supporting the growth of heather seedlings and cuttings. Effects were quantified using germination, rooting, plant colonization, plant survival under waterlogging stress and growth in height in experimental systems with and without liverworts and/or fungi. Fungal symbionts growing from liverwort rhizoids readily colonized the hair roots of ericaceous plants to form typical ericoid mycorrhizas. The presence of inoculum-bearing liverworts led to significant increases in plant growth. Erica tetralix was more responsive to inoculation than C. vulgaris. Ericaceous cuttings rooted and survived more successfully when they were coplanted with previously colonized liverwort stems. We demonstrate, under realistic ecological circumstances, that liverworts can deliver mycorrhizal inoculum and improve the establishment of vascular plants. We propose that by providing sources of mycorrhizal inoculum, symbiotic non-vascular plants can contribute to the restoration of plant communities dominated by Ericales plants. This research leads to broader knowledge about the function of ericoid mycorrhizas in ecosystems
