Syo Kurokawa


Syo Kurokawa was a renowned Japanese lichenologist and 1994 recipient of the Acharius Medal. He studied under Mason Hale and Yasuhiko Asahina.

Education and career

Kurokawa graduated in 1951 from the Tokyo University of Literature & Science, which later became the University of Tsukuba. He earned his Doctor of Science degree with a thesis titled "The species of Anaptychia, with a new sub generic classification". This work was later published as "A monograph of the genus Anaptychia" in 1962, which became a seminal paper in the field.
Throughout his career, Kurokawa made significant contributions to lichenology. He collaborated with Mason Hale on "Studies on Parmelia subgenus Parmelia", which revolutionized the understanding of rhizine characteristics in Parmelia classification. His research encompassed various lichen genera in Japan, including Anzia, Cetraria, Parmelia, Peltigera, Pilophorus, and Xanthoparmelia.

Contributions to lichenology

Kurokawa played a crucial role in elevating the herbarium of the National Museum of Nature and Science to international standards. From 1966 to 1996, he published the exsiccata "Lichenes rariores et critici exsiccati", comprising 700 specimens distributed to leading world herbaria. Between 1966 and 1987, he edited this exsiccata, collaborating with Hiroyuki Kashiwadani from 1978 onwards.
His research extended to environmental studies, where he investigated the use of Parmotrema tinctorum as a bioindicator for air pollution in urban Japan. Kurokawa's work earned him recognition as one of the most prominent lichenologists in Japan and Asia.

Legacy

Kurokawa was widely respected for both his academic achievements and his personal qualities, including his warmth and kindness. His passing in 2010 was considered a significant loss to the global lichenological community.
