Coniochaeta (Lecythophora), Collophora gen. nov. And Phaeomoniella species associated with wood necroses of Prunus trees
Provedor de dados: Naturalis Digital Academic Repository
Autores: Damm, U.; Fourie, P.H.; Crous, P.W.
Species of the genus Coniochaeta (anamorph: Lecythophora) are known as pathogens of woody hosts, but can also cause opportunistic human infections. Several fungi with conidial stages resembling Lecythophora were isolated from necrotic wood samples of Prunus trees in South Africa. In order to reveal their phylogenetic relationships, these fungi were studied on a morphological and molecular (5.8S nrDNA, ITS-1, ITS-2, GAPDH, EF-1α, 28S nrDNA, 18S nrDNA) basis. Some of the isolates were identified as Coniochaeta (Sordariomycetes), including C. velutina and two new species, C. africana and C. prunicola. The majority of the isolates, however, formed pycnidial or pseudopycnidial synanamorphs and were not closely related to Coniochaeta. According to their 28S...

Fungal trunk pathogens associated with wood decay of almond trees on Mallorca (Spain)
Provedor de dados: Naturalis Digital Academic Repository
Autores: Gramaje, D.; Agustí-Brisach, C.; Pérez-Sierra, A.; Moralejo, E.; Olmo, D.; Mostert, L.; Damm, U.; Armengol, J.
Severe decline of almond trees has recently been observed in several orchards on the island of Mallorca (Balearic Islands, western Mediterranean Sea). However, the identity of the causal agents has not yet been investigated. Between August 2008 and June 2010, wood samples from branches of almond trees showing internal necroses and brown to black vascular streaking were collected in the Llevant region on the island of Mallorca. Several fungal species were subsequently isolated from the margin between healthy and symptomatic tissue. Five species of Botryosphaeriaceae (namely Botryosphaeria dothidea, Diplodia olivarum, D. seriata, Neofusicoccum australe and N. parvum), Eutypa lata, Phaeoacremonium iranianum and Phomopsis amygdali were identified based on...
