Morphological studies of Lophodermium piceae (Fuckel) v. Höhnel on Norway spruce needles

Abstract

Morphological structures of the teleomorphous and anamorphous stages of the ascomycete Lophodermium piceae have been studied in detail. This fungal species is widely distributed and frequent on Norway spruce needles. The examination of many samples indicates that all belong to one species, namely L. piceae.

Diversity and Ecology of Endophytic and Epiphytic Fungi of Tree Leaves in Japan: A Review

“…Considering the record of over 1,200 species of trees and over 30,000 species of insects in Japan (Biodiversity Center of Japan 2010 ), future research will possibly reveal new and interesting interactions among trees, phyllosphere fungi, and insects. Another research fi eld that remains to be investigated is the histochemical observation of latent infection by endophytic fungi Acker 1987 , 1989 ;Johnson and Whitney 1989b ;Osorio and Stephan 1991b ;Deckert et al 2001 ).…”

Genetic relationships of endophytic Lophodermium nitens isolates from needles of Pinus strobus

“…2) implies that L. nitens is heterothallic. This provides additional reinforcement for the hypothesis (Minter 1981, Osorio & Stephan 1991 that the conidia, which are not known to germinate in culture, are spermatial and function in this species as gametes.…”

“…The infection of Pinus strobus by L. nitens ascospores has been documented on detached needles (Costonis, Sinclair & Zycha 1970). This is assumed to be the sole means of host infection, and the pycnidiospores are hypothesized to be spermatial (Minter 1981, Osorio & Stephan 1991.…”
