A large fruiting body of Bondarzewia berkeleyi (Bondarzewiaceae, Russulales) was collected at a woodland path in Kurokura, Yamakita-cho, Kanagawa and the dried specimen was deposited at KPM. Its pileus was 64 x 50cm broad and 21cm in height. The fresh weight of the sporophore was 5.5kg and the dry weight, 0.9kg.

Hypertrophic galls on Ipomoea triloba and I. lacunosa were found at Hiratsuka and Odawara cities in Kanagawa Prefecture respectively, in October and November 2005, 2006. The galls are produced on leaves, stems, petioles, buds, fruits and roots of the host plants and containing oospores. Usually, the white blisters (zoosporangial sori) are accompanied on the same hosts. Based on the optical microscopic observations, the fungus causing these gall formations was identified as Albugo ipomoeae-penduratae. This species was once reported 2000 in Japan, on cultivated Pharbitis nil, and its symptom is known as the "white rust of morning glory". Asexual and sexual morphologies are described and illustrated with time lapse micrographs of the process of zoospore formation and release.

We found a reddish brown pigmentation at a small stream of a biotope in Aina, Atsugi. As a result of optical and scanning electron microscopic observations, and elemental analyses, we confirmed that the coloration of reddish brown is originating from the iron oxide attached to the surface of cylindrical shaped microorganisms. Based on the morphological features, this microorganism was supposed to be a kind of iron bacteria and tentatively determined as Leptothrix sp., though further investigation is needed for identification.

A specimen of the labrid fishes was collected at depths of 60-70 m off west of Joga-shima Island, Sagami Bay on 7 February 2007. The specimen was identified as Bodianus cylindriatus (Tanaka, 1930) by having a combination of the following characters: scales on dorsal midline of head reaching in advance of above anterior extent of orbit; anal-fin rays III, 11(rarely 12); scales above lateral line 3(rarely 2); pored lateral-line scales 30-33. This occurrence represents the first record from Sagami Bay.
