SELECT tipo, STUFF((SELECT ', ' + CONVERT(VARCHAR, tipo) + ' - ' + descri
                    FROM table_t iT
                    WHERE iT.tipo = T.tipo
                    ORDER BY tipo
                    FOR XML PATH, TYPE).value('.[1]', 'NVARCHAR(max)'), 1, 2, '') AS id_descri
FROM table_t T
GROUP BY tipo

or more concise 

SELECT tipo, STUFF((SELECT ', ' + CONVERT(VARCHAR, tipo) + ' - ' + descri
                    FROM table_t iT
                    WHERE iT.tipo = T.tipo
                    ORDER BY tipo
                    FOR XML PATH('')), 1, 2, '') AS id_descri
FROM table_t T
GROUP BY tipo
