MUKERJI K.G., KAPOOR S. (1969): Fungi of Delhi. V. Some interesting Loculoascomycetes. Česká Mykologie 23(4): 256-261 (published: 15th October, 1969)
abstract
Four Loculoascomycetes from families Didymosphaeriaceae and Patellariaceae are described. Didymosphaeria mulleri sp. nov. and Valsaria mundkurina sp. nov. are new. Patellaria atrata and Rhytidhysterium rufulum are also treated, with detailed morphological descriptions.
JAMALI S. (2020): First report of Paraconiothyrium fuckelii (Didymosphaeriaceae, Pleosporales), causing stem canker of Rosa hybrida, from Iran. [Dothideomycetes, fungal disease, internal transcribed spacers, Iran mycobiota, pathogenicity.] Czech Mycology 72(1): 71-82 (published: 29th May, 2020)
abstract
In spring 2016, stem canker symptoms were observed on most Rosa hybrida plants in greenhouses of Kermanshah Province in Western Iran. Initial symptoms of the disease were brown necrotic lesions, mostly 8–10 mm long, on stems. The lesions eventually depressed and expanded to a long ellipse, resulting in yellowing and wilting of the foliage. Fungal colonies resembling those of Paraconiothyrium species were obtained from diseased tissues. Based on morphological and DNA sequence analysis of the internal transcribed spacers ITS1 and ITS2 and the 5.8S gene the fungal isolates were identified as Paraconiothyrium fuckelii. This is the first report of stem canker disease caused by this species in Iran. Pathogenicity tests were carried out on potted Rosa hybrida plants and detached branches under controlled conditions. Pathogenicity tests demonstrated that the fungus is able to infect and cause canker symptoms on inoculated branches of healthy plants after four weeks. The pathogen was re-isolated from all inoculated plants after observation of the symptoms, thus meeting Koch’s postulates.
RAVIKUMAR M., SRIDHAR K.R., SIVAKUMAR T., KARAMCHAND K.S., SIVAKUMAR N., VELLAIYAN R. (2009): Diversity of filamentous fungi on coastal woody debris after tsunami on the southeast coast of India. [tsunami, Bay of Bengal, southeast coast of India, woody litter, fungal diversity] Czech Mycology 61(1): 107-115 (published: 29th September, 2009)
abstract
Five coastal locations on the southeast coast of India severely disturbed after the tsunami on December 26, 2004 were surveyed for the occurrence of filamentous fungi on woody debris by means of short-term (1 month) and long-term (12 months) damp incubation. Short-term incubation revealed 26 mitosporic fungi (8 genera) ranging from 14 to 17 taxa per location with a total frequency of occurrence between 0.4 and 5.6 %. Aspergillus taxa were dominant and six of them were common to all locations.Long-term incubation yielded 35 fungi (25 genera) (22 ascomycetes, 1 basidiomycete and 12 mitosporic fungi). The total fungal taxa per location ranged from 25 to 28 with a total frequency of occurrence of 0.8 to 46.8 %. Corollospora gracilis was the most dominant ascomycete (46.8 %), while Cirrenalia tropicalis and Dictyosporium pelagicum dominated among mitosporic fungi (18 %). The total frequency of occurrence of 11 ascomycetes and four mitosporic fungi was above 10 %. Twelve ascomycetes and two mitosporic fungi were common to all locations. The richness of fungi was higher after long-term than short-term incubation. The occurrence of 61 fungal taxa in this study suggests that the tsunami-dumped woody litter on the southeast coast of India might have at least partially originated from the ocean, thus representing a mosaic of fungi existing in seawater and sediments.

SVRČEK M. (1971): Phoma muscorum E. Rostrup (New records. 9.). Česká Mykologie 25(4): 244 (published: 1971)
abstract
A new record for Phoma muscorum E. Rostr. is reported from southern Bohemia on capsules and setae of the moss Plagiothecium latebricola. Microscopic features are described and discussed in comparison with similar species and literature sources.
VĚZDA A. (1969): Beiträge zur Kenntnis der flechtenbewohnenden Pilze in der Tschechoslowakei. II.- Zwei neue Arten: Opegrapha rinodiae sp. nov. und Polycoccum galligenum sp. nov. Česká Mykologie 23(2): 104-109 (published: 1969)
abstract
Two new species of lichen-inhabiting fungi from Czechoslovakia are described. Opegrapha rinodinae sp. nov. grows parasymbiontically in the thallus of Rinodina nimbosa; first discovered in the Belauer Tatra, later found also in Norway. Polycoccum galligenum sp. nov. forms wart-like galls on the thallus of Physcia dubia in which its fruiting bodies are embedded; known so far only from SW Moravia.
