  • Fallen and living pine needles bearing ascocarps were collected throughout the country from February, 1987 to October, 1988 to identify and describe Lophodermium species associated with Lophodermium needle cast disease of pines in Korea. All of the observed characteristics of given species were compared with published descriptions of the Lophodermium species. As a result of this study, six Lophodermium species were identified and described. L. pinastri was previously recorded while the other five species, i.e., L. australe, L. durzlabrum, L. nitens, L. pini-excelsae and L. pini-pumilae, were unrecorded in Korea. One Lophodermium species has not been fully identified in this study, and tentatively named as L. sp-1. L. australe was observed on the needles of Pinus rigida, P. rigida ${\times}$ taeda and P. taeda, L. pini-excelsae on P. parviflora and P. strobus, L. nitens, L. durilabrum and L. pini-pumilae on P. koraiensis, L. sp-1 on P. thunbergii and L. pinastri on P. densiflora and P. taeda. L. sp-1 was collected from the diseased regions of 2-year-old needles of P. thunbergii and L. durilabrum from P. koraiensis, suggesting pathogenic nature of these fungi.

  • Fleshy fungi were collected during field trips to mountain areas throughout the country from October in 1994 to June in 1995. Through the observation and identification of specimens belonging to the wood-rotting fungi of the Aphyllophorales, one genus, Phlebiopsis, and six species, Athelia bombacina, Ceraceomyces sublaevis, Hyphoderma sibiricum, Hyphodontia arguta, Phlebiopsis gigantea, and Radulomyces confluens were confirmed as new corticioid fungi to Korea and are registered here with descriptions.

  • Two unrecorded naturalized species, Stachys agraria Schltdl. & Cham. and Dracocephalum moldavica L (Lamiaceae), are newly reported in Korea. Stachys agraria and D. moldavica were found at Seogwipo-si on Jeju-do and at ChunChen-si in Gangwondo in Korea, respectively. Stachys agraria is distinguished from other related Korean taxa by corolla of 2.4-5.2 mm long with six to twelve flowers in the node. Its local name is "Ae-gi-seok-jam-pul" based on shorter than longer corollar. Dracocephalum moldavica was distinguishable from other Dracocephalum in Korea by the following combination of characters, oblong to ovate-triangular ($1.7-2.4cm{\times}0.8-1.2cm$) leaves and rough crenate at the margin. This taxon is referred to as 'Hyang-yong-meo-ri' in Korean based on its fragrance. We provide a description, illustrations, photographs, and a key of related taxa in Korea.
